Would it be a bad idea to hook up a U.S. AC adaptor to a foreign generic Famicom system because of the differences in voltage -- will it "blow" some fuse or something?
Hmm...can't tell you, I ALWAYS use a Japanese one, because such situations can happen...
Well, I ask because I got a generic Famicom from Europe, and of course, it's got different prongs on the adaptor. I also think the generic Famicom takes a higher voltage than the regular Famicom, so I can't use the regular Famicom AC adaptor to run it. Looks like I might have to get a prong converter for that damn European P.O.S.
You should've bought a Japanese one, those AC Adaptors are VERY easy to get.
I have a Japanese Famicom -- the original kind. But I wanted to play around with a generic Famicom, so I bought that, too. And I have the AC adaptors for both; I just need to figure out how to get them functioning. I like the generic one because it got AV output.
Hooray! my Famicom finally arrived!!!
But I check the adapter, and low and behold... Input= "AC100V 50/60HZ 18VA".
Outlets here in the USA are 120V correct? So can I plug this Official Japanese Adapter into my US wall outlet? Would the 20V difference harm the adapter or my Famicom? I am sure somebody here knows the answer to my question.
.....urge to play.... rising.....
(Update: This is a HVC-001)
......must.....play.......Famicom......... :'(
You can get it to work, I believe. I have one and it works well...
Thank you!
No, I must find what the hell channel it broadcasts on. The AV mod tutorial that Kefka wrote says that it is 96 or 97. I do not see anything...
Actually, can you take a screenshot of your adaptor?
Yes, let me see if I can get my digital camera working long enough.
Man, the adapter is nice and cool to the touch, but the Famicom feels really warm right around the rear vent area, and I only played for less than five minuets.
Well, I could not find my digital camera's USB cable, so I used my PS2's "EYE TOY" insted.

This is the official "HVC-002" FAMICOM AC Adapter.
INPUT: AC100V 50/60Hz 18VA
OUTPUT: DC10V 850mA
(+)----(0----(-)
That's the one I have!
Oh good. Then it should be fine. Though I am seriously considering the AV mod. Although my TV picks up the ch01 signal on ch95, the picture and sound are not the best. Probably because of the differences in broadcasting standards between the USA and Japan.
Tell me though... does your FAMICOM get quite warm around the vent area after only a few minuets of use?
Looks like you got this pretty much resolved. But the official Famicom adaptor should work just fine. What an adaptor does is take the voltage of the outlet and convert it into the proper voltage for the machine. So, in your case it would work just fine.
I don't know about the heating up of the Famicom. I've never played mine. I don't have a TV with channel 95 capability.
Sometimes it does. Infact it did that for the first week. It worked fine later on.

Yeah, I have it all set up and running. Thank you for your time FamicomJL, and thank you for your input JC. I may now start enjoying my wonderful FAMICOM.
Ok...a question for anyone who knows...I've got this adaptor:
RINCO AC/DC ADAPTOR
Input: AC127V/220V-240V
60 Hz 50 Hz
Adaptor for 3600
+ --- C --- -
The prongs are foreign, so I want to know if I can just use a NES or Famicom adaptor in it's place? This is for a new Famicom pirate system I got today.
Chances are, you can not use an NES adapter. It outputs AC, and I can not think of a single system that does not use DC but the NES. I fried my real HVC-001 Famicom by trying an NES adapter.
---DO NOT USE IT---
Hehe...so I tried a NES adaptor. The system powered up but I got a black screen with a thick white moving line through the middle. I don't know if that means trouble or that I just don't have the right AV connections or channel for it. I'll keep working with it.
Yeah, don't use your nes adaptor with anything other than a nes! Most adaptors transform the electricity from AC to DC. The nes adaptor takes the voltage down but still puts out AC. But, on the other hand the nes is very resiliant and will take a lot of power adaptors...
Anypower adaptor that is not specifically made to work with both US and european adaptors will not work with both. Europe uses 220 where the US and Japan uses 110. You need a step down or step up adaptor to take 220 to 110 or 110 to 220.
Your adaptor says it wants 220-240 for it's input. Therefore, it will not work right in the US. I don't see the output on what that adaptor puts out. Does the system or the manual say what the system needs in volts and amps? It does output negative on the center (that's what the +----C---- - means). That definately does mean that it does not expect AC.
If you're not worried about playing it safe, try a super nintendo adaptor. At least then you're matching the center negative.
The strange thing about the adaptor is that it has a little switch that changes it from 127V to 220V/240V. But the prongs are foreign. Would it be possible for me to set it to 127V and mod it so the prongs fit a US outlet -- or will everything just burst into flames?
I was kinda wondering why yours said 127 and I didn't pay too much attention to the 50 or 60 part. Yeah if it's got a switch, you can try that with an adaptor plug. I think it would work. Being underpowered is better than blowing it anyway. Some countries actually use 127v--like mexico for instance.

This is what I'm looking at. I talked to the dude and he's a really nice guy. Also, I am to understand there is some sort of device I need to step down the voltage or something for a NA outlet. What is this and where can I pick one up?
As far as I've understood, the Famicom adaptor, which is what's in the auction, will work with the Famicom in the US/Canada without any problems. No step-down needed.
Ah, so that's where that went. I've already tried using my FC w/ an NES adaptor with no signs of smoke/explotions/what-have-you, but getting the adaptor wouldn't hurt anyway I don't think...
It's probably best to get the Famicom adaptor. I think the going rate is somewhere around $10-15 plus shipping. At least, I haven't seen one for less than that yet, but then again, I haven't been looking too hard.
Sounds good then. Good thing there's more than one night prowler around here; I'm busy for the rest of the week and would've been racking my brain about this the whole time.
Haha. Yeah. I'm usually not up this late during the week! You got lucky. And it's usually about this time of night that a few of the other members check in.
Excellent...
...I would still buy a step-down converter. My FamiCom no longer over heats now that I have one.
Where did you get yours? How much did it cost?
Ahem...HERE (http://www.famicomworld.com/forum/index.php?topic=281.15). ;)
Eh?
Reply #23. ;)
No clue what's going on :P
You asked where a step-down converter could be purchased, and I linked to the thread where super56k tells us where he bought his step-down converter. It's Reply #23 in that thread. It's got a big ol' picture of the converter, and the link right after the picture. ;)
Ok folks, the FDS board has a 9V Voltage regulator to regulate the incoming voltage off the power tip. The voltage regulator needs at least 9V or above to operate (I think the limit is 12V) You can also figure this out by multiplying the voltage of the C battery times the number of batteries in this case, 1.5V * 6 = 9V.
The key for this regulator is the AMP rating. Your amp rating has to be at least 850 mA. So, you can use any adapter that allows:
1. The center tip to be changed to negative . Usually adapters in US are set to positive,
2. The Voltage can be set to 9V
3. The amp rating at least 850 mA.
So, when I purchased my FDS last year, I went over to Walmart, I found a High Powered Adapter with 3-12 Volts, center tip could be changed to negative and the AMP rating was 1300 mA.
Question: Isn't 1300 mA too much?
Answer: No, because the Voltage regulator will only draw the current needed to run.
Question: The original FDS adapter is 10V? Isn't 9V too little?
Answer: No, the Voltage Regulator can Handle 9v or above.
Head over to Walmart and get your adapter. You can save your money to buy more cool things like a Famicom Keyboard.
Don't go to RadioShack unless you are desperate. RS charges way too much for their adapters.

In case you are wondering, I bought the PowerLine Adapter Model 0900-33
*smacks self in head* I never even dragged my mouse over that! Wow I'm an idiot...Next time i get paid, I'll definatly go for one of those converters.
Also, CFB's post is definatly going to save people a lot of cash on C cells (damn Satellite).
I got the adaptor today. I'll have to fight the urge to try it out on my FC to prevent it from lighting on fire for a few weeks. I'll get about $60 on the weekend from work, pay off a few debts, and then it'll be mine.
Bonus: The adaptor came in a Hershey's "Chocolate Ice Bar" box and instead of packing peanuts the guys used newspaper, both of which have Japanese all over them. I'll probably just keep these because they're so obscure.
You should be able to use any 9v center negative adapter on the FC and FDS. All the systems I've gotten from Hong Kong come with new, generic 9v adapters and I haven't had any problems.
Really? Around here, they say that w/o a step down converter it like cooking your FC alive...
I ended up trying it out anyway and it STILL doesn't work >:( ! Now I need a new one I suppose...here I come eBay!
If you have a 110/220 switching power supply, you don't need a step down converter. Most modern power supplies can switch between the two.
Unfortunatly, I don't have a switching power supply. I bought the orginal FC one

I'm sure it's legit, considering the source.
I just wrote this up based on Super56k, Chimy, michaelthegreat and madman's knowledge. Please comment on it, because I want to get everything right.
One thing I'm not sure of is whether the "specs" are different for the Famicom and Disk System. Plus, I do not have a set of recommendation for buying a Famicom-compatible AC adaptor that is different from the original.
...BELOW...
It is recommended that you use the original AC adaptor that came with the Famicom, Disk System and accessories when playing in the United States or Canada.
Famicom:
The Famicom AC adaptor is equipped with the same prongs, nearly the same input voltage (AC 100V) and the proper output voltage (DC 10V) as AC adaptors used in the United States and Canada.
Never use an NES AC adaptor with your Famicom. Most adaptors transform the electricity from AC to DC. The NES adaptor takes the input voltage down but still puts out AC, which is potentially harmful to your Famicom.
To prevent from overheating and damaging your Famicom, it is highly recommended that you use a step-down converter. Japanese electrical outlets output 100V, which is what the Famicom AC adaptor is made to input. United States and Canadian electrical outlets output 120V. Step-down converters that will convert the electrical outlet output to 100V are available online and in stores.
Disk System:
The Disk System is equipped with the same prongs, nearly the same input voltage (AC 100V) and the proper output voltage (DC10V) as AC adaptors used in the United States and Canada. has a DC 9V voltage regulator. The voltage regulator needs at least DC 9V or above to operate. (The limit is likely DC 12V.) You can figure this out by multiplying the voltage of the C battery by the number of batteries required: DC 1.5V x 6 = DC 9V. The Disk System adaptor is center negative. Adaptors in US and Canada are usually set to positive. The key is the amp rating. Your amp rating has to be at least 850mA.
So, you can use any adaptor in which:
1. The center tip can be changed to negative.
2. The voltage can be set to DC 9V.
3. The amp rating at least 850mA.
The original FDS adapter is DC 10V, but the voltage regulator can handle DC 9-12V.
To prevent from overheating and damaging your Disk System, it is recommended that you use a step-down converter. Japanese electrical outlets output 100V, which is what the Famicom AC adaptor is made to input. United States and Canadian electrical outlets output 110V. Step-down converters that will convert the electrical outlet output to 100V are available online and in stores.
I have a question:
The famicom ac adaptor output are 10V and how much amperage?
(sorry about my language skills).
Tks,
Ogrito
I had an HVC adaptor and it says that it puts out 10V, 850ma, center negative. That means that you either need a US power adaptor that puts out close to that or you need a step down converter.
The US snes AC adaptor is exactly a match for this power wise, but I don't think the plug fits in the FC. For the adventurous people out there, you could splice two cables together (US SNES adaptor to FC tip). If anyone wants to send me both a FC AC adaptor and a SNES AC adaptor, I'd like to try that as a test to see how it works. I would switch the cord completely, so there would be no splice. I don't see any reason why that shouldn't work. Since FC adaptors can be found for around $10 and SNES adaptors can be found at your local Salvation Army for $1.50, that might be a viable solution. I've been slow on everything lately, so plan on me taking two weeks if you take me up on the offer. I'd like to document the process for everyone. Remember kids, update your insurance before playing with powerful electric forces! :)
According to this website, the FDS adaptor is different. I personally really don't know. I'm not trying to contradict you.
http://maru-chang.com/hard/hvc/english.htm
ps JC I think we talked about the FDS adaptor earlier, and I think yours came with a 10V 850ma center negative. Did the snes adaptor fit your FDS? Does the snes adaptor fit your FC?
From what I've read, it doesn't seem like a little heat is a problem. Most electronics emit some heat while running. The Famicom has some metal dillywho that's made for collecting and emitting that heat. But, don't forget super56k's (I think) advice about cooking your Famicom alive. US/Can outlets are 120v, while the Famicom wants only 100v. Step-down converters ensure you won't damage your console.
I bought a Famicom AC adapter on ebay and when it finally arrived, I plugged it in on my Famicom and I had a big problem. The Famicom outputted a buzzing noise and a weird distorted black screen. Also, the AC transformer feels loose when I move it (like something is moving inside the transformer)
I tried my Sega Genesis model 1 AC and it works fine. Does that mean that my Famicom AC is faulty or is it because I have to get a step-down converter?
For the record, my Famicom is AV modded and it's a HVC-001. The AC adapter that is having problems is a HVC-002 adapter.
Anyone know what AC I'd need to run a Game Doctor and Turbo GD6+?
I use my extra famicom adapter or 9v Center tip -.
Yep, almost every copier ever made uses the same power adapter.
Just found out something.
The Sega AC adapter will work on the Famicom? Because its ODC 9V (dunno the right way to say it)
Will that work?
Yes, the US Genesis 2 (the smaller, square one most commonly found) has an AC adaptor that works with the Famicom and most Famiclones. In fact, every Famiclone I own except for the Handy FamiEight uses the same AC adaptor. They're all interchangeable.
I bought an AC Adapter from store which is universal.
I have a huge problem. When I change to ODV is 9 and when I plug it in.... to test it out and then I left it on the ground. Few minutes (like 30-45 mins) I smelled something funny and tried to figure out where that awful smell coming from. I realize It's my AC universal adapter making the smell. I quickly took it out and let it rest on the ground.
So, Um why does it do that?
P.S. I plugged it on the long plug thing (you know you can have many plug in it, I don't know the name of the long thing is) instead of the wall outlet.
Thats odd. It shouldn't really matter what the imput is (unless your in Europe) since there isn't much difference between Japan 110 and US 120 volts. The only that that'll really matter is the output. You need 9volts DC 200mA + -------- - polarity. No Famicom or Famiclone I own has ever given me any problems like that. Maybe your Power Bar is no good?
However on the back of my adapter there's a swtich 200-240V AC and 100-120V AC.
Which one should I use?
Also in the front I put in 9 for volt change and what is the POLARITY thing do?
EDIT: Here's my adapter that I have http://www.shoppingwarehouse.net/prod-80552.html?src=froogle&src1=sw&src2=gbase&utm_source=Froogle&utm_medium=Product%2BSearch%2BEngine
You're in CA...you should use 100-120V since US outlets are 120V. If I remember right, polarity should be + ----C---- -.
Does anyone have any pictures of which Sega's power adapter that works well? I tried to find some but there's many different kind.
Thanks.
Edit: I have Sega Genesis MODEL: 3025 adapter. It's input 120V 6-Hz 15W and Output is 9VDC 1A
+ -()- - (the polarity thing)
does that work? or is it dangerous?
Wow, how many times do we have to cover this same exact topic in this thread? A Genesis power supply works fine.
I'm not sure; can I use a genesis adapter with the Famicom Disk System? If not, what adaptors would work with it?
It's good to see you people caring so much about the power requirements of your systems. I usually get loads of fried consoles (especially famiclones) because somebody plugged in an incorrect power adapter (especially Atari power supplies) or destroyed the entire RF board by plugging AC into their poor systems (I've seen that happen to a SNES... oh the suffering!!!)
Maybe we need some pictures of the adapters and their correct settings here to illustrate people, when I get my digital camera back I'll upload some ;)
EDIT: BTW, the toaster NES uses AC, but it can work with negative tip DC just fine.
How many times is it possible to say the same thing and still have people ask the same exact question?
People don't like to search...that's the nature of forums...you post your question and get an answer.
You can find FDS AC requirements in Workshop on the site.
I've got a question that I'm almost certain I already know the answer to, but I want to confirm. I've discovered I can power my giant toaster NES with my Famicom 100v adaptor. Will that harm my NES in the long run?
The NES expects 9V AC but it will also work with negative tip DC. It has a bridge rectifier built in, getting DC into that actually LOWERS the voltage by 0,7V (by the semiconductor nature of the rectifier diodes) so the marginal amount of overvoltage you are seeing on the secondary caused by getting ~20V extra on the primary is actually diminished. I don't see why you make such a fuss about it :P Also a +/- 10~20V is in the margin of tolerance of most equipment.
If you want to be reeeeeaaaally kind with your NES/Famicom, get a 9~12V regulated switching well-filtered power supply with at least 2A of current capability. But my systems are happily chugging along with unregulated wall warts ;D
Good to know, but I'm not sure if my question was answered or not! ::)
Will using a 100-240VAC AC 9v DC 1A AC adaptor in a 120v wallsocket on a NTSC Nintendo Entertainment System cause the console any harm?
Just respect the polarity if it's DC. (Negative tip)
I'm afraid I'm not so sure about how to read polarity. My adaptor looks like this if you can discern what it means:
((( - (ยท +
I hope this quick Mspaint drawing I made would clear any confusions left about how to power your systems ;)
hmm.....it looks like the one I have is a positive tip then. What does that mean in the long run?
It means that your Famicom/NES won't work with it, and if you leave that plugged in for too long you'll burn the voltage regulator and other things of your RF board.
Long story short: Reverse polarity damages your NES/Fami. (it has some reverse polarity protection, but if you leave it in that condition too much time they'll eventually overheat and short).
I'm looking into grabbing a Twin Famicom, but the one I'm looking at has no AC adapter. Is the unit compatible with another system's AC adapter? If not, what are the specs on it so that I can find one myself?
I don't know about compatibility, so I took a photo of my Twin Famicom AC adaptor for your reference. :)
(http://img118.imageshack.us/img118/4484/cimg0007hs8.jpg)
Thanks for that. So does this mean I need an adapter that can handle 1.25A, or could I get away with one that was rated for 1A? A quick glance over Walmart and Radioshack's websites found nothing that could handle anything more than 1A.
It'll work just fine.
Hello,
I have just bought a Twin Famicom system, looks nice and everything - problem is I live in the UK (Britain) so it won't work with the power from my wall socket.
I have a step-down adapter which works with many other Japanese systems but not the Twin Famicom. When I plug it all together (console, power supply, step-down adapter) and press the power button the power light comes on for a split second then goes away, this can't be right can it?
Does anyone have any ideas why the other Japanese systems work with the adapter but not the Twin Famicom?
Any help would be appreciated as I would like to use the system but don't won't to blow my console and house up trying.
Many Thanks
Ross
it means the twin is broken
Test the AC adapter in another system or with a multimeter to see if it is the culprit.

No need to be an ass, kite. Not everyone knows the ins and outs of this stuff.
:) the one thing I can think of is that the AC is fried but not the console
Is that even possible?
Yeah it's possible. It happened once to my Atari 2600.
I have three power supply related questions:
1. I bought a Super Famicom from a used video game shop and the power adapter it cam with was a Sega adapter, I believe from a Genesis, although it may be from a Mega Drive.
My question is, will this cause damage to my console in the long run? I have already played it a little and everything seems to be working fine, but I just want to make sure.
2. Do I need a converter for a Famicom AC adapter to convert to a north american outlet?
3. Do I need a converter for a FDS AC adapter to convert to a north american outlet?\
I tried searching around some other forums and stuff but it seems like nobody had a straight answer. Thanks in advance.
The difference in volts from Japan to America is 10v which is nothing. A stepdown converter isnt needed.
As for the adaptor, I have no idea. It would be best to use a Nintendo brand HVC-02(I believe thats the model number) adaptor to avoid any issues though.
1. No, it will work fine.
2 & 3. No, but some people here recommend using a 110->100V stepdown transformer. Personally I think that ~10V extra is no big deal, if in doubt, get good quality generic replacements (MW sells some good NES/FC/SNES compatible power supplies).
I bought the Famicom, and Famicom Disk System, from eBay. The Famicom arrived in good shape, with the official Famicom AC adapter. The Famicom Disk System arrived with many deep scratches, and did not include the official Famicom Disk System AC adapter, even the the add stated that it is mint, and complete. I could not get both systems to work, and while trying to get them both to work, I used the NES AC adapter on both systems, which may have ruined them. I need two AC adapters to play the Famicom connected to the Famicom Disk System, and since I do not have the Famicom Disk System AC adapter, I thought I would use the NES one. Later on, I also used the NES AC adapter on the Famicom, and I used the Famicom AC adapter on the Famicom Disk System, just to see what would happen. No signs of either sytem, frying occured. The Famicom Disk System lit up for 5 seconds, stopped, and never lit up again. I have filed a dispute with the seller of the Famicom Disk System, and I should recieve a refund. I may have to send the system back, but that's okay. I already bought another Famicom Disk System on eBay for cheap, so hopefully, this one will have no problems. I may know someone who has an official Famicom Disk System AC adapter, but if not, I could always use batteries. As for the Famicom, perhaps it still works, but I just need to hook it up properly. Also, when I opened up the Famicom Disk System, there was a screw missing, and at that point, confirmed that it was just a piece of junk, so it may go back to the seller, and I should get my refund, since I always pay through Paypal. I don't have any Famicom games, so I have no way of really knowing how it would work, but apparently, a gray screen comes on if no game is inserted, and I couldn't even get that, for my screen remained blue. So much hastle, just so I can play Super Mario Bros. 2 on the Famicom Disk System.
Yeah using the NES adapter with the Famicom is a big no-no. You'll have to check the voltage regulator and associated circuitry on both systems.
Let's say the NES AC adapter damaged them. Can they be fixed? If I check the circuit boards, how would I know what is damaged, and how would I be able to repair it? No smoke, or any indication of them frying, ever happened. I don't even know if they got fried. I never even got them to work before.
Should my Famicom Disk System power up, by itself, not connected to the Famicom, is plugged in with the official AC adapter, or does it have to be connected to the Famicom? Even if my Famicom Disk System does not work, being plugged in with the official AC adapter, would putting batteries in make it work? I have one official Famicom AC adapter. Do I need two official ones, to get them both to work?
First, how is your electronics knowledge? So I know where to start ;). Can you recognize simple electronic components? Do you have a multimeter? Soldering iron? Know how to solder? etc.

Yeah, also it's going to be downright impossible to do any kind of troubleshooting with at least a multimeter. You need to check if power is reaching the 7805 voltage regulator, and then check if 5V are coming out of it.
I do not have the Famicom Disk System AC adapter. I only have the Famicom AC adapter. I have been using the Famicom AC adapter, after using the NES adapter on the Famicom Disk System. Would both not work for the Famicom Disk System? Would the Famicom AC adapter work for the Famicom Disk System? Maybe that is why the Famicom Disk System is not working. Could this be so?
NES ac adaptor will ruin both of those.
Famicom ac on disk system will ruin the disk system
Umm, no. It's the opposite. The NES adaptor will ruin them... :|

Yeah, it gives me laziness to read the long thing all over again. Clear, concise data please ;).
And I'll say it again, you need AT LEAST a multimeter to do any kind of troubleshooting. Get a cheap one at your local Home Depot or something. To go further, you'll need a low wattage soldering iron and some electronics solder (60/40 with flux core is fine). Get the cheapest ones too, no need for fancy stuff. Also get two replacement adapters, 9VDC negative tip. Model 1 Genesis adapters will work fine for your Famicom and FDS :).
My super famicom AC Adaptor works on both :)
Yeah, but we don't know if he lives in a 110-120 or 220-240V country. A SFC adapter on the latter would go *boom* with lotsa smoke and possible damage to the system.

and the Famicom AC does not work with disk system.
anyway, can we get a mod to CONSOLIDATE the posts in this thread? or just make me a mod ;D

Why? FW says they're the same. Technicals please ;).
You said they will both "ruin" the system.
All I've ever heard is that the FDS works with a famicom adaptor.
I live in a 120V area, I believe, in New Westminster, British Columbia, Canada.
I always thought we were 100v haha. Oh well, but yes.
Japan is the only 100V country in the world. Others vary between 110 and 127V.
I just bought a sharp twin famicom on ebay without a power cord, and I emailed Pink Godzilla and asked if the universal(ish) one they sold would work with it, they said it wouldn't.
I'm new to this, so I don't really know what to do.
You need one with a 9V DC output, 850mA minimum and negative center. ( + )--->C<---( - )
Careful! Reverse polarity will make your Twin go BANG!
The famicom AC and disk system AC are not the same, the differences are in bold:
famicom:
AC-Adaptor
MODEL HVC-002
AC100V 50/60Hz 18VA
DC10V 850mA
+ ------ C------- -
disk system:
AC Adaptor
MODEL HVC-025
AC100V (50/60Hz)
9VA
DC9V 400mA
+ ------ C------- -
The difference is so small it's not going to hurt anybody. Maybe the current rating of the FDS adapter is a little low but in practical purposes you won't notice it at all.
thanks for clarifying but im not going to find out
Will...
* Too low a voltage rating hurt my Famicom? - No, it may work erratically or not at all, but no damage.
* Too high a voltage rating hurt my Famicom? - Only if it's something ridiculous, 12V tops.
* Too low a current rating hurt my Famicom? - No, it may work erratically or not at all, but no damage.
* Too high a current rating hurt my Famicom? - No, a higher current rating is better, the transformer will run cooler and the Famicom just takes what it needs
* Reverse polarity hurts my Famicom? - YES! I know AV Famicoms have reverse polarity protection, and thanks to 2A03 that Twin Famicoms do not! So better don't try it, you may blow capacitors and regulators, and possibly other things.
* NES adapters hurt my Famicom? - YES! They're AC and the Famicom requires DC, you may blow capacitors and regulators and possibly other things.
Disclaimer: No Famicoms were harmed in the realization of these experiments, just Famiclones ;D
wow.. good to know ;) thanks, i didnt knew that
So, i need a " 9V DC output, 850mA minimum and negative center."
If i find a "9V DC output 850mA minimum" with a positive center, can I just switch the pins on the plug to switch the polarity?
I've never done anything like this.

What do you mean by that? Also, it doesn't have to be exact 850mA, it can be more and it will be fine.
Sorry, I don't really know what I was thinking.
I found something.
The output is 12VDC 1200mA.
The other post said 12V tops, and I dont want to hurt it.

I just bought a FDS without a power adaptor (though they claim it's working) and I plan on getting some NiMH C cells. One less cord anyway.
It could work if the polarity is the correct one, but a 9V one would be best. It will still work, it will just get a little hotter. (The 7805 regulator inside takes the variable 9V from the transformer and gives a steady 5V output, the other 4V are dissipated as heat, so with 12V you still get your nice 5V output, but now you're dissipating more heat (7V)).
Okay, I'm going to make sure I find one that I know will work before I do anything.
On the back by the power hole, it says it needs a positive center.
Huh?

Rechargeables are 1.25V unlike alkaline which are 1.5V, so instead of 9V they'll give 7.5V . If your FDS struggles to work, think about the batteries before anything else.
EDIT: Wrong number of batteries, thanks nurd!
similar to PONG.
it needs six 1.5 volt AA batteries, or a 9V wall thing in a weird size.
is this the right thing?
I can't really tell from the description. :P

But will it work as one?
Can i plug one end into the sharp twin famicom and the other end into the wall and then play it?
Famicom' s HVC-002 input is AC100V 50/60Hz 18VA, output: DC10V 850mA, polarity: + ------ C------- -
I am from Europe and here is 220V voltage. Famicom needs 10V 850mpA, and I have already Sega Megadrive 2 (US - Genesis), and it's adaptor is input: 230V ~ 50Hz, output: 10V 850mA 8.5VA, polarity: - ----- C ------ +
Model MK-1636-18
As can be seen, the output is the same, but I worry, that SEGA's adaptor is connected to 220V voltage net (Famicom should get power from 100-120V net), also polarity is different. But result is completely same: 10v 850mA.
May be someone have an advice to this situation, don't want to burn the console.. :]
hello slavco,
if you have a famicom adapter use a stepdown. thats enough. 8)
Just found this articles:
http://ntsc-uk.domino.org/archive/index.php/t-65940.html
http://ntsc-uk.domino.org/showthread.php?t=50065
There is written, that FC/SFC can be used with PAL Megadrive's adaptor.
Anyway I should buy step up voltage converter from 100V to 220V, to use console gently :)
That may only be the case for PAL (HK) Faicoms though. Get a stepdown converter to be safe.
If an adapter expects the right power and outputs the right power, it will be fine.
You have to know what the adapter expects. If it expects 220 only, the output is only correct for 220. If it only expects 110, it only runs on 110. If it expects either, it should give the right output no matter what.
It's output needs to match too. The voltage can be a little higher than what you want and the ma can be higher also, but the center positive/negative does need to match. There is a lot of confusion about the center voltage in video games circles since the American NES doesn't care. But that's about the only system.
Neither of the 2 power adaptors you have are a match that will work. You will fry your system with either one (on 220).
As said get a stepdown and use the original adaptor. You could also modify the extra adapter to output the right polarity (simplest way is to cut the wire and splice it back with each wire going to the oposite--then you couldn't use it with the Megadrive). You can also find an ac adapter meant to work on 220 that does output correctly and has a tip that will fit. My local thrift store has boxes of these on one shelf. That would be a good place to start.
i bought a universal power supply(?)
and it can deliver 9V or 12V - but not 10V
12V is too much right? but 9V?
9V is exactly the kind of voltage the stock Famicom PSU uses.
Yeah 9 and 12V are ok, but respect the polarity! That's the most important thing. Remember the Fami is center negative.
Quote9V is exactly the kind of voltage the stock Famicom PSU uses.
really? on my Famicom is printed 10V... thats why i was worried, but i will use 9V then ;)
Thanks!

Close enough. Since the Famicom has a voltage regulator (which almost every video game console has) you can use any power supply from 7V to 12V, so long as it's the right polarity and amperage.

Hooray! my Famicom finally arrived!!!
But I check the adapter, and low and behold... Input= "AC100V 50/60HZ 18VA".
Outlets here in the USA are 120V correct? So can I plug this Official Japanese Adapter into my US wall outlet? Would the 20V difference harm the adapter or my Famicom? I am sure somebody here knows the answer to my question.
.....urge to play.... rising.....
(Update: This is a HVC-001)
Never plug it directly into a US outlet, you need to purchase a Step-up and Down power converter.
20V is nothing, if it outputs 10V with 100V, it will output 12V with 120V. But here seems to be mixed opinions about it.
Hi. I just bought an AV famicom system from ebay. But the one I bought doesn't come with the AV cables or the AC adapter. I already have a super famicom with the AV cables and AC adapter for the super famicom. I wanted to know if the AC adapter for my super famicom will work with my AV famicom. I looked at your website but couldn't find any information on the AV famicom. I'd really appreciate some help wtih this question. And I'd even more appreciate a section of your website for the AV famicom and the NES II. Considering they're nintendo products and they're famicom models.
I've moved your post here beause we've got lots of information about AC adaptors here. Also, you can find plenty of detailed info about the Famicom AC adaptor on the website, under the Workshop section.
(And you're right, we do need some pics and info about the AV Famicom. Just don't have someone to work on it right now.)

I use a standard 9v adapter on my Famicom all the time with no step down converter and I have never had problems. I actually purchased it from pinkgodzillagames.com
The Pink Godzilla adapter is also decent, sadly they no longer stock this item.
Hey I have a question. I have a super famicom. It came with the standard HVC-002 power adapter. I live in Canada so we have 120V AC 60Hz outlets. But my super famicom works fine using the HVC-002 adapter plugged straight into my wall outlet. I just got an AV famicom from ebay and according to websites it uses the HVC-002 adapter. Do you think it's safe for me to keep using it plugged into my wall or should I get an expensive step-down thing that converts my outlet power to japanese standards?
I say it's safe since a +/-20V difference is inside the tolerance rating, but here seems to be mixed opinions about this.
Transformers are linear devices, if it steps down 100V to 10V, if you feed it 120V it will output 12V, which is just a 2V difference, nothing to worry about since the Famicom can work from 7 to 15V with no problems.
For an objective review, test it for a while. If the adadpter or the Famicom gets too hot to the touch, then get a new power adapter (it's cheaper to get a new adapter than to get a 120 to 100V step down transformer).
^ while it's cheaper in the short run to buy another power adapter, if you are an import gamer it is much better to just buy a stepdown converter so that you don't have to continually buy power supplies

ahh thankyou so much. I ordered one, I really hope they have some insurance if it gets lost in the mail. I really can't wait. Also, where can you buy a hvc-002 power adapter?
Check ebay, sometimes you get lucky.
Original HVC-002 is available on eBay separately, costs about ~ 25 GBP (~50$). Also you can try http://www.play-asia.com/
Anyway the best decision is - use original adaptor with step up/down converter. This is 100% safe.
I do not know much about US/Canadian voltage net, but in Europe my AV Famicom works fine with step up (110-230V / 45W) converter. Adaptor never goes to heat up for long playing, it also make a pleasure.
I also found this

I contacted them and according to them it will work in canada. I hope they're not lieing.
toysonlinehk are good relieble service, think it will be OK
This idea is so simple and obvious someone else must have already thought of it,
so somebody aught to be able to tell me if it's a bad idea before I actually do it.
The idea is a means to cheaply and relatively easily solve the voltage problem
one encounters when using a Famicom in the U.S.
I noticed that the SNES adapter appears to have an identical output as the Famicom adapter
but only the cord from an NES adapter will fit into the Famicom, so...
What I've done is soldered an NES adapter cord into an SNES adapter, thus creating (I hope)
a Famicom adapter that can be plugged into an American outlet.
I really don't want to bake my Famicom into a FamiFritter, so if any of you know something I don't then PLEASE stop me before I plug it in.
I do not see any reason why it wouldn't work.
My main uses a original adapter with a step up and down converter, but I use a yobo super nes adapter as a secondary for my other Famicom; and it hasn't died yet.
Famicoms are alright with DC 8v-10v, usually.
Just make sure you get the correct polarity! That's all.
Yup, the polarity's right, positive over negative.
I can use it then without fear of The Blue Smoke of Death.
Thanks very much for your help!
Yes, great minds think alike. You did actually take apart the snes adapter right? It look so much better.
And pay very close attention to what 133mhz said. Remember that if you put the wires backwards, the polarity switches! Test the polarity before you plug it in. Use a multimeter.
I saw some info on this site http://www.vidgame.net/misc/POWER_PLAY.htm (http://www.vidgame.net/misc/POWER_PLAY.htm) and I found one at the goodwill yesterday but it came with no AC adaptor? What adaptors can I use for it? Thanks in advance and I do have the AV cables so it's not a problem. AWAAAAAA
Hey there all. I'm a new member here (this is m first post, but actually joined a bout a week ago).
I recently won an eBay auction for a Famicom A/V.
Here is a link to the auction (with pictures): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=270243786750
Now my question is... will the included AC Power Supply work for me (since I'm from North America, and the Power Supply is Japanese). I do not wanna fry or harm my system, so the advice ou guys give me is what I'll follow.
The item just arrived about 20 mins ago, and I'm dying to fire it up...
If it means anything, here is what's written on the AC Adapter:
AC-ADAPTER
MODEL HVC-002
AC100V 50/60Hz 18VA
DC10V 850mA
If the above AC Power Supply will not work in my country (Canada), can you tell me what I will need to play it?
Thanks in advance to all who reply.
Dan :-)
If you're in the USA or Canada, it will work w/no probs.
I had been under the impression that because US outlets push 120V, it was necessary to get a stepdown power converter or an AC that would take in 120V and output the same as a Famicom adaptor.
Yes, USA uses 120V and Japan uses 100V. Most appliances won't mind a +/-20V difference in their input because they're designed with reasonable voltage fluctuations tolerance in mind.
Now the Famicom adapter specifically is a simple 60Hz transformer, diode bridge and filter capacitor. The transformer output voltage is proportional to the input voltage and to the number of turns on its primary and secondary windings. Since the number of windings doesn't vary with time (unless you take it apart or something :P) the only variable is the input voltage.
If the transformer takes 100V at its input and gives 10V at its output, then it has a 10:1 turns ratio.
Given that, if you give it 120V, you'll have 12V at the output, a miserable 2V difference.
The Famicom doesn't care about such small difference since it regulates the input voltage down to 5V with a voltage regulator chip (the famous LM7805). This chip gives a steady 5V output from an input as low as 7V and as high as 30V, dissipating the excess power as heat through its body (and into the heatsink on the back of the Famicom, that's why it gets warm while playing). More voltage, more energy needs to be 'wasted' as heat.
So in fact you can run your Famicom on voltages between 7 and 15V with no problems whatsoever!
Hope this answers the question once and for all ;D
It does clear everything up. Nice explanation. Somewhere someone once said that extra voltage would slowly fry the Famicom. Glad it doesn't. Well, I've got a stepdown anyway, so it makes little difference to me, I guess.
Is there a Famicom AC adapter that accepts 120 V 60 Hz electrical power input?
Because if I were to use an official Japanese HVC-002 Famicom AC adapter, I'd need a voltage converter to make sure the Famicom gets the correct power (since I live in the US).
But if I could get an AC adapter that accepts AC 120 V 60 Hz and outputs DC 10 V 850 mA (with the correct plug for the back of the Famicom), I could bypass the voltage converter and plug my Famicom directly into the wall power outlet.
So, does such a beast exist?
Use the same HVC-002 Famicom AC adapter, you can use it in the US just fine.
If you're still worried, use a Sega Genesis Model 1 AC adapter.

Yeah, if I remember a long time ago somebody said their famicom ran hot and asked if it was ok to use the JP adapter. I said I don't have a famicom but if you think it's the power you might want to get a US adapter with the same power or a step down converter. He did and he said it solved his problem. Then others asked if they needed that and I said I don't know. If should be fine, but if you want to be super cautious, you can. I think that's where it started. So it's partially my fault. :) We should go back and delete some of those old posts or sticky this info or something.
Start a stickied post with:
In the us you have two good options:
1. Use the original adapter
2. Use a US adapter that puts out the same power
In Europe you have two good options:
1. Use the original adapter and a step down converter
2. Use a 220 adapter that puts out the right power
Never use a NES adapter
Then give the power adapter specs for the famicom, disk system,l etc.
I recently acquired a Famicom and FDS from a friend of mine through a trade. The Famicom, unfortunately, stopped working but I have since purchased an AV Famicom to replace it. For the broken Fami, I was given a Hori AC Adapter (HA-7) to power it. The info shown on the label is:
AC100V 50-60Hz 16VA
DC10V 850mA
+ ----C---- -
It worked fine on the Fami and anything we tested out afterward. So, after such a long-winded lead-up (XD), my question is if this adapter might work for the FDS, since I did not receive an AC adapter for it? I know that the Hori AC is not the same as what the official FDS AC provides, power-wise, but is it enough of a difference that could potentially put the FDS in harm's way if I were to use the Hori adapter on it?
No problems. It will work perfectly with the FDS.
Quote from: 133MHz on September 25, 2008, 03:11:41 pm
No problems. It will work perfectly with the FDS.
Spiffy. So, the 9VA difference doesn't really matter? That was my only real concern, since I know a 1V difference on the DC and the extra 450mA wouldn't really pose much of a threat of blowing out the FDS.
Update: Indeed, it works dandy. Tested it out when my AV Fami arrived this morning. The FDS runs nice and cool. :D
I should have an AV Famicom coming my way soon, but I'll need a power supply for it that can be used here in the UK. Does the standard Famicom use the same power supply as an AV Famicom?
I was looking at the one listed on here: http://www.robwebb.clara.co.uk/shop/nes/nes.htm (http://www.robwebb.clara.co.uk/shop/nes/nes.htm), which says it can be used for a Famicom, but was wondering if it would be okay for an AV Famicom too.

Thanks a lot ;D
Would I be right that using a UK NES adaptor to power a Famicom in the UK is a VERY bad idea? I'd assume the UK NES outputs DC AC and 220V can cook, no? Someone did this on another forum.
UK NES AC adapter should have the same output of a US NES AC adapter (9V AC), only the inputs differ to take the line voltage from the country it's being used. So it would do exactly the same as somebody in the US powering his Famicom with a NES AC adapter.
Now if you plug a US/JP AC adapter (100-127V) into a UK socket (240V), then you're cooking with power!
Transformers are linear devices, so if your transformer is 110V in - 9V out, then feeding it 220V in would get you 18V out, with two possible outcomes:
1) The transformer was designed to tolerate twice the input voltage on its primary and will happily churn out 18V at its output.
2) Smoke, sparks and flames since it was not designed to handle twice its input rating.
I see...so the only problem then, like with the US NES adaptor is the AC (said DC earlier, I meant AC).
EDIT: For some reason, I never thought of a power adaptor as a voltage regular on it's own; lowering the power from 120V (or whatever) to what the device needs. Seems so obvious. What's the point, then, of the Famicom having an internal regulator?
A transformer can step a voltage up or down since it's a linear device and it all depends on the turns ratio of the windings and the input voltage (i.e. if you build a transformer with 120 turns on the primary and feed 120V into it, and build a secondary of 20 turns and another with 9000 turns, you'll get 20V from the first one and 9000V from the other one, couldn't be simpler).
Ohm's Law states that voltage is the product of the current by resistance (the famous V=I*R) and also that power is the product of current by voltage (P=I*V). So when voltage goes up, amps go down, and when voltage goes down, amps go up. Everything is nicely related and so you can step the voltage up or down for any given power.
But there's also one more thing: the output voltage from a transformer varies with the load attached to it. If you measure the output voltage from a Famicom plug pack rated for 10V with no Famicom attached you'll get a wildly high reading like 20 volts but if you load it with a Famicom you'll get something closer to 10 volts. This is because the load increases the current (and the power used) and therefore lowers the voltage.
As you may have imagined, the Famicom doesn't always use the same amount of power, it depends on how hard the CPU is working, how many accessories are attached to it, how big is the game, etc. This would mean that the voltage would never be constant, it will be always varying depending on the situation, and that's no good for digital circuits (where 0 and 1 are represented by specific, steady voltage levels) and analog circuits (where i.e. video brightness is represented by a voltage value).
So then, the Famicom's internal voltage regulator is an integrated circuit whose task is to maintain the output voltage at a constant 5 volts no matter how much the input voltage and the output load vary. You can feed any voltage from 7 to 24 volts and load it up to 1 ampere and it will always keep its output at 5.00 V (the excess power is dissipated as heat through its body, that's why it's screwed to a big aluminum heatsink which gets hot during use - for 9V operation it wastes 4V as heat).
And you guessed it: The 05 in 7805 is the output voltage, so a 7810 gives 10V, a 7824 gives 24V, etc.
Hope this clears things up (and I hope I didn't bore you to death ::))
Hoyl carp, that's actually really fascinating. I took a bit of this in school for a physics class, but didn't do much beyond that. It's messed up how the direction of current is backwards because of the assumption of a "positive" flow -- and yet we find that electrons are negatively charged and actually move in the opposite direction. And yet if you flip your circuitry, it will screw everything up (unless I misunderstood). Very, VERY weird.
I suppose then that if P=I*V and V=I*R, then actually P=I^2*R?

Sup dudes. I tested out my crappy famicom today with my turbografx-16 psu and it was a success! So I guess you can add it to the list of compatible psus. heh. Its a little low on the milliamps, but it gets the job done. :)
Turbografx-16 psu

I am planning to buy a famicom, but cannot find the ac adapter. i am wondering if a super nintendo's ac adapter will work. it inputs AC 120v 60Hz 17W and outputs DC10v 850mA
No it will not. NEVER EVER use an NES/SNES Adapter with a Famicom. Bad things will happen :(
About the only way to use a Famicom on an American TV is with the original...or very close to original adapter and (optionally) a step down converter :-\ ..which I highly recommend.
This is what you need in addition to the original DC Adapter. http://www.voltageconverters.com/itemdesc.asp?ic=VC100J
You can probably find the original Adapter on eBay for a low-considerable price
American SNES adapter plug won't physically fit your Famicom
Japanese SFC adapter will work perfectly with your Famicom
European SNES adapter will fry your Famicom
You can buy a universal ac adapter at Radio Shack that will work. That's what I use--it outputs DC 10V @ 850 mA, center negative.

The NES and SNES adapters are very different. Not to be a dick or anything, but you should do a little more research before claiming "Bad things will happen".
Yeah but you still can't use either one with a Famicom,,,RF Switch maybe..but not AC Adapters
I'm looking for an official Famicom AC adaptor, but can't find one - would this work?
http://www.amazon.com/General-Electric-BLACK-UNIV-ADAPTER/dp/B0002YE3NY/ref=sr_1_3?ie=UTF8&qid=1230432226&sr=8-3
300 mA is too low for a Famicom. Get one with at least 800 mA of current capacity.
You can't use a SNES one with a Famicom because the plugs are different, not because the voltage is incompatible, in fact if you were to wire a correct plug to it, the Famicom would work perfectly. Now the NES AC adapter is physically compatible but the voltage is incompatible, using a NES AC adapter with your Famicom will blow it up.
So would this work?
http://www.amazon.com/General-Electric-UNIVERSAL-AC-ADAPTOR/dp/B0006U82HW/ref=pd_bbs_sr_5?ie=UTF8&s=electronics&qid=1230432919&sr=8-5
Or would it a splode my Famicom?
Yeah that works.
I think it is the duty of Famicom World to record video proof of an NES AC adapter exploding a Famicom. It's just the right thing to do. :)
Unfortunately blue smoke and explosions would be pretty rare. The NES AC adapter is a silent killer :-\.
If you want movie-like explosions from a Famicom, wire 220V directly to it.

Too bad there isn't a video section...
and Doc's Youtube accounts keep getting canceled :P
For the record, I must say that I wired AC to my SNES once, my uncle fixed my SNES AC adapter and thought that it used AC instead of DC. When I turned it on it made a horrible noise through the TV speaker and the picture was like the SNES had a little too much LSD. It was so horrible I turned it off immediately. Luckily my SNES survived unharmed, not even its fuse blew up, but it only suffered for like half a second.
I learned my lesson, though. Never trust my uncle for gaming stuff ::)
Hehe, what kind of horrible noise? Was it like a really high pitched beep and loud static? That would majorly rape the ears....
It was low-pitched loud static, sounded like electrocution in the movies. It was pretty obvious that my SNES was in pain. I could feel it :-[
lol well I hope it isn't suffering...or you're gonna need to put it out of it's misery :'(
No no, it survived unharmed ;D
Good for your SNES, it may need a psychologist though....you know....mental trauma..
Hah, I am familiar with that horrible low pitched scream. :P
Also, I'm confused. I was reading the Famicom Power thread and one guy says that the Genesis 1 adapter works and another says the Genesis 2 adapter works. Which one is it?
Genny 1. Genny 2 has reversed polarity. Always check for negative tip when looking for a Famicom adapter.

Yes, the US Genesis 2 (the smaller, square one most commonly found) has an AC adaptor that works with the Famicom and most Famiclones. In fact, every Famiclone I own except for the Handy FamiEight uses the same AC adaptor. They're all interchangeable.
That means Satoshi_Matrix lied to me! I feel misled. :(

Does the famicom work in an standard US outlet because US = 110V, JP = 100V. would it fry my famicom or would it work perfectly fine?
should be no problem.
If you'd like to be 100% safe, there are always step-down converters.
I'll second that. You shouldn't need to get any adapters or anything for it to work, but I got one anyway just in case. They are only about $15 or so. Some people have problems using there famicoms without one, and some people have no problems. Try yours out first at home, and if it gets really hot, or if you have a lot of problems with glitches and bad connections, then it couldn't hurt to see if a converter would fix it.
i haven't got it yet and i live in sweden so im gonna have to get a power adapter first

I got an adpater for a famiclone that outputs:

mod edit: combining double posts
I want to try out a Game Doctor I've got, but I'm wary of using the wrong power adaptor. Any clue which one I should be using? I had heard the FDS adaptor would work. Is that true?
EDIT: I've got a 9V center neg. and 350mA.
I got a Famicom Disk system off of ebay but it did not come with a power supply. I get error which is obviously because they're is no power going to the FDS. Is it safe to use a NES power supply that came with my NES? I tried that and I'm getting errors 21 and 22 is that because I'm using the wrong power supply?
Oy! :-\ Read through the thread or check the Workshop section on the site. I'd very strongly recommend you stop using the NES adaptor.

Yes...very sad..long, long time
I didn't know there were on-screen errors for power adapters on the FDS... then again I'm sure there's an error for everything. ::)
The error messages are unrelated to your power supply. See here:
http://www.famicomworld.com/Disk_System/Error_Messages.htm (http://www.famicomworld.com/Disk_System/Error_Messages.htm)
They are essentially saying that the disk failed an anti-piracy check. In reality, though, it's probably your drive failing to read the disk for some reason (either the drive needs adjustment, or the disk itself is corrupt....yay floppies!).
I got it from ebay and the guy supposed replaced it with a genuine rubber belt but it came with no power supply so I used the one for my NES and I get error 2 which is a battery error so something is wrong here. I opened my French Doki Doki Panic and got error 22 after trying my Volleyball? Disk it came with.
Plausible explanation, pulled out of my technological a**:
- The FDS only uses its external power adapter to move the drive motor.
- The FDS power input has a rectifier diode in series as a reverse polarity protection.
- That diode would turn the NES adapter's 9VAC into something between 4.5 and 15 V pulsating DC
- The pulsating DC is moving the motor, therefore the motor is moving very slowly and/or stuttering
- The rest of the FDS logic is working OK, but thanks to the erratic movement of the motor the data is coming out garbled, and in consequence errors 21 and 22 (and possibly 27) are showing up.
Once again, I've repeated it countless times:
DON'T use a NES adapter to power Famicom gear.
did I break my FDS? :o :'(
Edit: I did not break my FDS. I tried it after buying 6 C batteries! I beat Doki Doki Panic with Mama!

Yes, don't use a NES adapter :)
Well I'm glad it works and I should be getting an adapter soon from
.https://famicomshop.com/catalog/20/systems
Is it necessary to use the original adapter with my Twin Famicom, or can use another adapter as. I've heard that a NES adapter is a no-go, but that I could use a Megadrive adapter. I'm not sure about this though and don't want to take any risk.
I use a multi volt adaptor for mine. Bought it cheap on eBay. Basically comes with a load of switchable connectors at the end so you can select the right voltage then use the correct bit. Does the job but I wouldnt recommend using any others from different consoles.
If you have the original AC adapter, use it connected to a 220 to 110V stepdown transformer.
PAL NES Adapter = NO GO indeed. I use a universal adapter with 7,5v and the correct pin (- / -) (don''t know which one). I can take a look when I got home.
Only problem with the Twin Famicom is a greyed palette on some (older) TV's in Europe.
Don't just plug in a regular Twin or Famicom adapter into any old outlet in Europe...
Calls for explosions...get a step-down converter and then make sure you have a compatible AC adapter. You can't use a NES one or a FDS one if you were thinking about it ;)
Thanks for the reactions.
Would this one be ok?
http://www.gameland.nl/catalog/index.php?main_page=product_info&products_id=281
I assume tha one would be ok.
Yes that stepdown converter would be perfect.
Question about Super Nintendo power thingy.
For some reason I have like 7 NES power kajiggers.
I cannot find my single SNES power thingy.
Any other power thing I could use, or make work with it?
NES adapter == BAD. We've discussed that issue to death around here.
If you're inclined, you can install a bridge rectifier and a filter capacitor inside your NES kajigger to turn the AC into DC.
There's no issue using an official Famicom Disk System AC adapter in the USA, right?
Found the SNES power thing in the back of...Sock drawer. What the hell. xD
I have several motherboards, an old laptop and a file server on the shoe storage thingie of my closet.
I'm a dude so I don't have like a million pair of shoes as women do, that empty space needs to get filled up with something :P
I have a ton of stuff under my bed xD
Japan has it easy.
Famicom and Super Famicom use the same adaptor. :D
@rudos
If you have any questions about your Twin Famicom, I can answer them.
I have a Twin Famicom, and I'm in the Netherlands also ;)
You Dutch guys should get together for a Famicom session. You don't live far from each other. :)
i use this type of power-supply for my twin-famicoms.

Okay, is it fine to just plug the official Famicom Disk System AC adapter into an American outlet and not have it do any damage to the system?
I've heard of people using step-down converters, but don't electronics like this usually have a voltage tolerance?
wont hurt a thing ;D
Welllllllllllllllllllll.............
The FDS voltage is just like the Famicom's, so if you use a stepdown for that, get a surge protector, and plug the FDS in it too.
I do this just to be safe, and so far, it's worked! :D
Yeah, I'll be using a power strip with a reset switch. ;D
With a stepdown converter right? You plug the power strip into the converter, then plug both of the power adapters into the power strip
Here's what mine looks like, instead of a power strip, I just took one of the add-on things because it takes up less space. It came with the power strip, so I figured what the heck. Sorry for the crappy quality. I used one hand to hold it, and the other hand to hold the camera :D

I was just planning on plugging it into the strip. :-\
You don't need a step down converter,dork is just over cautious.
Yeah, I wasn't sure whether I really NEEDED it or not.
I might even try using batteries with it as to not clog up my already spiderweb-like game setup. How can it even be powered by only six C sized batteries anyway? I thought this thing was supposed to be a power hog. I have one of those octopus plugs, and they don't work so well with those big box converters. My power strip is actually designed with an extra space so you could fit three boxes on it if you wanted to.
I personally would not have the boxes like that, they don't look to be in too securely. I would have used one that is set up in branches, or even better, one of those "power squids".

Well, since it kind of shares power with the Famicom, the only time it really uses power is when it's loading something on the disk. The batteries can last for months.
Any power supply's life is shortened by constantly being connected to power. Also, the slowly drain power even when the system isn't being used. To solve all those problems, I just flip the breaker on the power strip when I'm not using my Famicom.
That's what I do to my stepdown, since my power thing doesn't have a switch.
Both adapters work just like any American adapter because both are NTSC 60Hz.
For the input...
Not the output :D
And last I checked, my power lines provided AC, not NTSC. Though, picking up mysterious TV signals off my power lines would be interesting. Anyway, the important thing is that the frequency and voltage are close enough between US and Japan not to matter.
I have the same stepdown transformer as Dork, and I also noticed that it has a fuse in it. It's great to have in the event of a power surge and your fami doesn't explode. :)
Yes, plus it came with 2 more fuses in case the first one burns out. :)
I was wondering if anyone could give some advice i live in australia and just picked up a famicom,disk system,and a turbo game doctor 6 with a heap of disks only problem is it has no leads was wondering what type of power supplys to use and what type of R-F lead to use any help would be appreciated thanks btw great site...happy easter to all
Famicom uses 9v DC, the DC part is very important because AC will Nuke it.
The Disk System can run off of batteries.
And a regular NES RF switch will work on the Famicom, using channel 95 in the US. I am not sure if its the same channel in Austrilia.
I was thinking anything I can get in a store. Any brands I should look at? And, what kind of adapter am I looking for exactly? Bear with me, I know very little about electricity.
For a Famicom? I know a Turbografx16 adapter will work...if you have one of those. I know you can get a regular universal adapter, but you have to switch the polarity, I think.
But I don't have a TG16 adapter. Are they cheap? And do they come separate from the console? I need 2. And, it's a Famiclone, ot a regular Famicom.
Any of these will work:
- TurboGrafx 16 adapter
- Sega Genesis Model 1 adapter
- Famicom/AV Famicom/Super Famicom adapter
- Cordless phone/cassette player/etc adapters that output 9V DC negative tip.
Check out thrift stores and flea markets for loose junked power adapters, you'll probably find several compatible ones for pretty cheap.
But I don't live near any. The Hamptons suck if you're a gamer. :(
Only rich people live in the Hamptons. Have your parents buy you one online. ;)
I had a SNES backup unit (Game Doctor SF7) that had an obscure power adapter requirement, but a Genesis (version 1) cable worked with it.

Not always true. I'm middle class. Anyway, my initial question was never answered; are TG16 power cords cheap, and do they come separate from the console?
They do come separated, just like every other AC adapter.
Are they cheap? I have no idea, but you have lots of alternatives to choose from.
This should do the trick for $7:
http://www.bluerosevideogames.com/proddetail.asp?prod=SG-P-085-N
It isn't a TurboGrafx 16 adapter, but it's among those listed that are said to be compatible. It's the same one I bought for my backup unit. (Genesis 1 model)
That's a Genesis 2 model, isn't it?
Nope. The model 2 adapter is smaller and has a yellow tip.
I actually have an extra official Nintendo Famicom AC Adaptor. If anyone is interested, PM me.
Thanks,
Carl
Does it have an American plug?
Japanese and American outlets are virtually the same.
hi sorry to reserrect a resonably old thread, but I just recently bought a famicom for the cheapest I could find, which is in a very decent condition. Only catch was, it wasnt provided with the orginal adapator for the console. I think I got the RF connector part sorted, but I am alittle bit apprehensive about using a personal ac adaptor for the power supply. as it was stated on this thread japanese use 100v range, but the power supplies here in the uk is like 220v-240v. I read on a previous thread that "so long as the out put is below 12v and above 9v, the famicom should be fine but I wana clarify with ppl whether or not these adaptors I got on me would work or just fry my console.. here the two adaptors I got and their ratings:
Binatone airlink 800
input:AC(~)240v 50hz 13W
output:DC(:::)12v 500mA
polarity: (+) - (o - (-)
alba type 8A
input: AC 230-240v ~ 50hz
output: DC 6v ::: 600mA
polarity : (+) - (o - (-)
(the ::: is basically a straight line with 3 dots underneth, couldnt work out how to type that part out, sorry for confusion)
I havent seen any post from uk (europe) players who own a famicom, except for 1 post but I feel I need more elaboration on what is best, I dont know much about electrics and stuff but want to see if I could get away with using these adaptors rather than having to buy the orginal 1, and then a converter.
The Binatone airlink 800 adapter should work perfectly, the other one doesn't provide enough voltage (won't cause any damage but it won't work either).
any AC Adapter with an maximum output of 12V would fit in. coz inside the famicom their is this Voltage Regulator transistor that regulates it into 5V. ::)
Does a genesis power supply work with a famicom? Or any other power supply?
Yes, a Genesis model 1, and a TurboGrafx16 power adapter will work with the Famicom.
Thank you! I will use a genesis model 1 power supply!
genesis is 9v i guess? it should still be regulated inside into 5v. so yes its compatible.
I also have shmuper1988's problem. From what I'm hearing in this thread, this will work?

"Input AC 120V 60Hz / Output DC 9V- 850mA"
I'm in the US, and I think our house voltage is different than the UK's.
Yes it works, but that particular AC adapter is terrible. Don't be surprised if it breaks after a few days or weeks. Of course, YMMV.
Well, maybe if I'm extra careful it will last. The power adapter I got with my Super Joy 3 TV game still works fine after 5 years of service, and that thing is super cheap. (That darn thing is currently what I use to play all my famicom games. The N64 design is so uncomfortable!)
I just got my Twin Famicom in the mail today. I have a 3rd party power adaptor that I am using to power it up. It's a Sanyo Japanese 100v AC Adaptor, with what appears to have negative center polarity.
(http://img156.imageshack.us/img156/3973/sspx0063a.jpg)
I do realize that the Twin Fami calls for a positive center adaptor. I didn't notice this until after I had played it for a total of probably 2 hours off and on throughout the day. I had no problems with powering it on, but now I'm not going to use it again, because I found this info out. Obviously, I shouldn't use this adaptor again, to be on the safe side, right?
Did it come with your Twin Famicom? If so, I bet that it was modified to output center positive polarity by the seller, since it wouldn't work at all with reversed polarity. If you have a multimeter you can eliminate all doubt.
alright. Thats good to know. If you want to call this a stress test for the adaptor...
-I beat the first world of Doki Doki Panic with mama
-Beat the first 3 dungeons on Zelda no Densetsu FDS
-Beat the first world on Nazo no Murasamejou
All in one sitting, and I tested out several other fds and cart based games.
I guess i'm good to go. I didn't consider that the adaptor could have already been modified.
I don't know if this question has been answered yet, but I purchased my famicom and disk system in two different auctions. The disk system came with it's original power supply, and the famicom did not come with a power supply. Would it be possible to use the disk system adaptor on my famicom and just use batteries on my disk system?
Unfortunately not. The voltage is compatible but the tips are slightly different in size and thus not interchangeable :-[.
I guess I'll just have to go with this...

Famicom AC adaptors are hard to find these days by the looks of it.
What's up guys. I have a question for those of you who have a Japanese Famicom, may be you can help. I just bought this Famicom or Family computer console with it original box and manual, AV cables. The Famicom has RF output and video/audio output as well. The system is like new, it has not lost its original color and all the outputs i describe above look very good, still with its chrome-round outputs. The only thing that the system did not include was the AC adapter. This Famicom was made in Taiwan, distributed in Japan. The system has the "VIDEO GAME" sticker in the front instead of the "FAMILY COMPUTER" logo. The system is just like the Japanese Famicom, red and white, the controller or joysticks have turbo buttons. I want to see if someone out there knows if i can use My Orifinal Famicom adapter with this Famicom from Taiwan. THe instruction manual is all in japanese and I understand nothing about it. Thanks guys.
It's most likely a famiclone, not a real Famicom. I have one with a similar sticker/name on the front, but it's not authentic Nintendo hardware. Red & White Famicom's were never made with AV outputs, just RF. They likewise weren't made with turbo buttons on the controllers.
You'll probably be fine with a 10V, 850mA, center negative ac adapter, the same specs as the original Nintendo adapter.
Yeah. Thanks for responding. I've seen some Famiclones grey and white with AV and RF outputs, with the "Family Video Game" sticker. All made in Taiwan.
Does The Disk System need a watt conveter or something or can i just plug it in?
if it is a famicom ac adapter is it okay to use in a 110-120 country im in north america
No problem if you're in the US. Go ahead and plug it in. ;)
So I bought a Famicom Disk System recently, but the seller sent the wrong AC adapter with it (needs an HVC-025; they sent an HVC-002).
The two adapters have different power outputs. I'm relatively certain this will spell disaster if I try to use the HVC-002 with my FDS, so are there any common alternatives to the HVC-025 that match the FDS? I'd rather not pay for 6 C batteries... :-\
It should work fine. I use my Famicom adapter all the time with my standalone FDS.
The adapters are the same voltage and polarity wise. The only difference is the diameter of the barrel plug.
Will a Genesisi AC adaptor be fine to use on an NES?
I read the specs & everything is the same except that the NES has 1.3A & the Genesis has 1.2A.
Also, one of the Genesis adaptors is 17W and the other is double that. Does that make a difference? ???
A Genesis Model 1 adapter works perfectly on a NES or Famicom. Don't worry about the minute differences, as long as the voltage and polarity are the same and the current ratings are close enough you should be fine. ;)
Hi guys,
I want to use an AV famicom in the US. I could buy a HVC-002
Input: AC100V 50/60Hz
Output: DC10V 850mA + ----C---- -
or i was looking at the SNES AC adapter, SNS-002
Input: AC120V 60Hz
Output: DC10V 850mA + ----C---- -
anyone know if there are any problems with using the SNES AC adapter?
it looks like the output looks fine... not sure if the pin size is the same though
***Update***
HVC-002: Plug Outer Diameter 5.5mm / Inner Diameter 2.1mm
SNS-002: Plug O.D. 7.5mm / I.D. 4.5mm, with a pin 1mm
The SNES's actual plug is physically too large but you are correct in saying that it has the perfect voltage and amperage ratings.
What I did was get an old aftermarket SNES AC Adapter from Radio Shack. It worked but because the adapter plug is at a right angle, I had to prop up my AV Famicom on some books until I got a FDS.
I usually just use my PC Engine Super Grafx adapter with my AV Fami. The plug is the right size too! I heard the Genesis adapter also works?
I used my old original Famicom AC adapter on my AV Famicom, but you could use a Sega Genesis adapter if you wanted.
So I got a Genesis model 1 power adapter 'cause I read here it'd work on a Famicom, but I discovered that the polarity for the adapter and my Sharp Twin is different. Does the Twin have different polarity than the regular Famicom or something? What should I do now? I don't want to have to use the super expensive stuff from Radio Shack.
Yes, the Twin's polarity is different. Just cut & switch the wires on your Genesis adapter & you should be good to go.
Okay, cool. I'll do that. Thanks!
Something I figured out today and might be useful, the DC plug used in the Famicom is a 2.1 mm Barrel type connector.
Well first of all iam new here and want to say HI to all of you Retrofreaks ! :D
Tommorow iam getting a second handed Famicom system , but without a Power adapter :/
After reading and searching true alot of forums & topic's etc , i still have 1 question.
What if i use an European NES Adapter and plug it into a stepdown converter is it possible for a stepdown converter to also output DC?
BTW iam from Europe , The Netherlands and we use 220V.
Mabey there are some other Dutch people here who can help me buy a adapter that works like from a laptop or any otherkind.
Best Regards
Myst.
European NES adapter outputs AC, and you need DC for the Famicom. (I got mine from Germany, it's AC/AC, believe me).
Stepdown converter is used for (for example) 220V adapter to run in an 110V outlet. The output is always from the adapter so there's no change to that. Buy an AC/DC adapter (Converts AC to DC) with the needed specifications and do not use NES adapter.
In other words, if you try to use a European (or any other) NES power supply on a Famicom, you can expect it to instantly destroy it, or at least damage it in a way that prevent it from functioning until repaired. I can't stress enough: Never attempt to use a NES power adapter on a Famicom, or any other system.
You can buy a 200VAC->10VDC adapter easily enough, and your Famicom will thank you. :)
I'm going to have to keep this in mind.
So are the lower voltage AC Adapters that will work on Famicom readily available in the US?
I'm wondering if I should buy a couple extra in my last months here before coming back to the states... Keep stocked up just in case.
I Just got my Famicom !!!
And i found 2 Adapters. (Found it in the house , the console itself did not came with any power adapter!)
Is this a good one to use ?

And how should i set the buttons/switches.
Thanks !
Hmm the second one ("HQ") looks better although both look a little cheap :) and probably won't be ideal but would do ok.
So if you use the second one, set it to 9V and the polarity should be set like it is pictured on the lower picture - there is a plug on the cable that can be switched/turned, minus must be inside! (the small arrows must face each other)... post a pic of it if you like to check it's all right.
Thanks for the info.
I will post a pic in a few minutes.
But what should i get then ? instead of these cheap things something like a universal laptop adapter??? i really have no idea....
And also i cannot set the Polarity on the HQ one because i thought it was a switch but actually its just a LED :/
Thanks.
We had this discussion already
http://www.famicomworld.com/forum/index.php?topic=5580
Yes i have read the topic you just stated.
Thanks anyway. ;)
Remember this: Big and heavy (and expensive) is better than small and lightweight (and cheap). Or search for something from a well known manufacturer.
Well i have tested it with 9V and after 20 sec it got pretty warm on the bottom near the power input when i was searching for a channel i immidiatly disconnected it because i got scared ! , further i dont smell any burning whatshowever i dont know what i should do.
Should be okay (the Famicom), but do not try that adapter again. Those cheap adapters can have different output than is written on them. Try to measure the output if you can.
Phew Thanks , tommorow i will take it 2 a Electronics expert , so he could test it and further on what will happen if you put the polarity wrong?

I don't k ow what you mean by 'readily available', but I have around 600 of them (NOS high quality, solid ones from the 90s, not the cheap-o junky featherweight ones made today) in stock. Available at local stores? That depends on the area...
For some reason I can't find the correct dimensions for the twin famicom power supply plug.
I have a 2.5x5.5 mm that fits. Is that the best measurement?
This topic should be moved to technical and repair. (sorry for the bump :D )
