Title: Famicom Disk System error 2
Post by: ulera on August 15, 2012, 11:50:58 am
So I finally got a game in the mail for my FDS system, I load in my C batteries and I fire it up... and all I get is error 2. I can actually hear the FDS make noises like it's trying to read the disk so I'm more inclined to think this is a belt slipping error then a battery error. How do I fix this?

They're brand new. I bought them just today.

Yeah. It said error 2 means no disk power supply. I have six brand new batteries in though. According to another thread in this forum it said error two could possibly be caused by a belt slipping. Any chance it could have gotten bumped out of place during shipping?

Well that's $11 down the drain. What brand would you recommend?

You don't have a PSU you can use?

Rayovak Alkalines are fine, but the "Heavy Duty" and the like are gutter trash. I suspect one or more of the batteries are just bad, maybe they were on the shelf too long.

Any non-dollar store alkaline should be fine, I got some at Fuji alkalines at Big Lots for $6 total for mine.

Hopefully they'll take then back at walmart.

I MAY have a psu i can use, how many mah can a disk unit safely take?

Doesn't matter about mAh, it will only take what it needs. All you need is a PSU that's 9V or 10V with the right sized plug with a negative tip. A Famicom, Mega Drive 1 PSU etc will work fine.

Well... the only ac adapter I have is the one that came with my famicom an its rated too low for US outlets. So should I try my luck with batteries again or buy a psu?

If you're in the US, a Japanese 100V AC adapter should work fine. What are the specs on it?

A Japanese Famicom PSU will work fine in the US.

Are you sure? Because in the adapter thread it said it may get damaged over time.

Load of rubbish, it will be fine. The power from your wall is not at a set voltage and will fluctuate by 20-30 volts either way, appliances are not as sensitive to voltage as people often assume.

In any event, if you are still concerned, don't use it on a long term basis, just use it for the sake of quickly testing your FDS out. I guarantee you it will not be damaged, and if it is I will buy you another one. :)

So I tried my famicom ac adapter... it still gave me error no 2. I swapped it for my third party adapter running my av famicom and now they both work. Any ideas why the famicom psu wouldn't work on it?

No idea why it wouldn't work.

So, are you saying that the FDS is now working correctly? If so, great! :D

Other than it not working when powered by an actual Famicom ac adapter it is. But the 3-1 multi-system adapter I picked up at the local retro game shop seems to be working fine.

There is a 0.1mm difference in the size of the plug between a fami and FDS PSU, but this has never been a problem for me before.

Anyhow, glad it's working alright now, so what disk games do you have?

Just Super Mario Bros. 2. I'm hoping to scoop some more up from 80'sFreak and Manuel next payday though.

What makes you say that?

you said it made a noise
Title: Re: Famicom Disk System error 2
Post by: ulera on August 16, 2012, 02:44:36 am
Normal, disk reading noise. Same noise it made when it was running on ac power and working fine.

I'd try the batteries again.  :D

Alright. I'll get 6 new batteries and try again. Let me know how your test goes.
