Normally I would complain about gutting something like Mario's Cement Factory, but this is too awesome.  I love that it even works with the FDS ;D

Can you please explain the 50 to 60HZ mod? I'm very curious about that cause I know only about one working method, and it requires changing the xtal and also the PPU... ???
And what means "reversed cammera"?

I think he's referring to those cameras you can install on the back of your car, which hook up to an LCD mounted somewhere on the dash, so that you can see what's behind you.  I think he used an LCD from one of those kits.

just change the xtal and solder to join two separate there below the motherboard

50/60 NOAC are all the PPU and CPU are inside you can not change is only activated and deactivated with points solder

There are many varieties of motherborads, but basically is the same, if in doubt put a detail of a famiclon and tell you to join points

car monitor, sorry  ;D

Thank You! Thank You! Thank You!  :star: :star: :star: :star: :star:

EDIT: I replaced the xtal with one from a Power Joy and soldered together the points like in the bottom pic. This method should be stickied in the forum, or added somewhere where people can find it easily.

Post by: jpx72 on October 05, 2011, 09:47:20 pm
WOW very excited!!!!! :crazy:
I must definately try it!
But is the solder point always near the NOAC glob? When you, cmv2, will be here to identify the point by looking at the photo, then great!

By the way ericj, do I understand it correctly that you soldered 3 points together?

EDIT: WOW I now realized that you were talking about keyboard NOAC.... I HAVE THE SAME!!! WOW NTSC Keyboard famiclone!!!  :pow:

Sorry for stealing your topic CMV2 but your information is golden! Can somebody tell me the frequency of NTSC xtal? I want to take a look on the web for some manufacturers (and I don't have any NTSC machine at hand right now)...

EDIT: found it! 21.47727 for NTSC and 26.6017125 for PAL :P

another trick, if you cut this track will get the extra Famicom sound, for games like Castlevania 3

on other boards would have to cut and get the sound of the pin 46 in this single cut

Definately not. You need NTSC PPU for NTSC output and vice versa (CPU is universal). Those glob-top famiclones are build for multiregional use (now we know!) and manufacturers just switch the xtal when they export to NTSC/PAL country accordingly.

Wow! I'm impressed, and the folks here can tell you that happens very infrequently...!

What would you charge for a duplicate of this, and are you talented enough to make one using genuine Nintendo parts (thus, no clone-news involved)?

A long time back I cut a ColecoVision in half and folded it 9the PPCB, joining the connections with jumper wire), making a console less than half the original size. Someday I'll post photos of that, if it is of any interest.  :bomb:

Are you sure about CPU ?
NTSC and PAL systems use different CPU's.
Just PPU and XTAL swapping enough for convert a PAL system to NTSC ?

Well in may be a little tricky AFAIK, but it worked on my famiclone (http://jpx72.detailne.sk/collection_files/consoles_files/famiclone/austria_1.jpg) and on my Rev.07 Famicom (talking about exchanging the PPU+Xtal only). So I can definately confirm it. But it may not work on all famiclones.

So I tried to solder all 3 yellow points together - according to the last uploaded picture, but it didn't start up. Then I also soldered the red point, but it was the same. BUT I am trying it with a slightly different xtal (20,996MHz), so that may be the problem (although my other famiclone worked with it on NTSC, but that may be just coincidence, everything depends on the whole oscillator circuit so...). I should have some original NTSC xtals soon, and then I will test it properly. I will report after that!

I looked closely, and saw that this pin is audio.

please take a picture with details of your motherboard to compare dentenidamente modified, because the photo with which to compare is not clear

Can you perhaps explain in detail how your determining which pins are suitable for this modification? It looks like in most cases the pins are close together on the board in 3 points, but I'd like to know more about it because sometimes it's not very obvious.

I have no more information, sometimes together and others are farther apart and in some cases can not be made, there are lots of NOAC models and do not know the pinout, I can only help as I know there is little

other side of the board, I've got my eye on those pads above the crystal. You can see where it matches up with the first side by that diagonal hole.

Any ideas, are these photos good enough? (PowerJoy is a pain inside, to get the best photos I'd have to unscrew another couple of boards) - I've just ordered the 21.xyz crystal, so am feeling optimistic - cheers  8)

Those 3 jumper pads should do the job (closed them to GND) while replacing the Xtal

Thank you! So to be clear, the three bottom pads can all be drawn together and connected to GND at one of the top pads. I'm considering running that and the crystals through a DPDT switch, should that work ok? No reason it would interfere with the crystals' timing?

All of the upper pads closer to the cartridge connector are GND, and if the jumpers need to be closed just link them together. After a closer inspection looks like there are more jumpers under (covered by) the Xtal. I'd like to see what's under there, they could be the ones. Does this power Joy has built-in games?

You could also link them one at the time until you find the correct setting, trial and error sort of speak.

In theory that should work unless there is some sort timing delay issue.

Thanks again! Yes it has some built in games, in one of the smaller glops presumably. I don't think there are any more jumpers under the crystal, there's one big plain square that the top of the crystal is soldered down onto, and I think that's it, but I'll get a closer look to be sure next time I go in! New crystal and switch should be arriving in the next day or two.

I have seen in other Power Joy units jumpers for the built-in games, so there could be more jumpers than expected.

Judging by the pics looks like there very well could be some under there, the big plain square is GND and at times, the frequency jumpers are near by it, also the traces are usually closer to the Xtal.

If you don't mind me asking, where are you getting your NTSC Xtal from? I ask because all of the ones I've seen are not directly drop in replacements and have different specs, the applications for them might be in series or parallel and might not be enought to pull the frequency within tolerance.

Thanks, yeah I don't know anything about different types of crystal, I just googled the frequency and found the easiest place to buy one on its own, so I got it from here (http://www.mutant-caterpillar.co.uk/shop/product_info.php?products_id=4135) - the fact that it says "suitable for NTSC Famicom System" was reassuring tho
It arrived today after all, not much to look at - it's very short, height-wise, compared to the existing crystal. No markings except for the frequency on the top, so it doesn't matter which way around it goes?

Yo are good to go with that one  8)

Any side is fine. Don't forget about the possible jumpers behind the current xtal  :question:

Yep for sure, will have a good look when I crack it open again, hopefully tomorrow if the switch arrives.

Update: no other jumpers behind the crystal, just the one big ground square. Gonna have a play and see what happens...

Another update, got it working :) can switch between pal and ntsc, but annoyingly out of the three televisions in the house, only the tiny one in the spare room displays ntsc in colour. Doesn't look like there's any way to get pal60 out of this thing, and certainly no rgb, so will have to make do. It doesn't bode well for my plan to get a real famicom at some point, but then again we are wanting to get a new tv when we can.

Thanks again for all the help! :D

Cool, congrats! so what did you do in the end, closing all of the jumpers?

I'd say that's important, having a multi system TV or one that's NTSC compatible  ;D

Yep closing all the jumpers worked perfectly. Hm now I can't help wondering what the three jumpers do individually, and if that could lead to pal60. Not sure I can face further experimentation tho, at least not any time soon, this was a stretch of my extremely amateur soldering skills..

If I'm not mistaken , closing one or two jumpers may give a different variation like NTSC 3.58, NTSC 4.43 or even PAL/60Hz.

Arg, guess I might have to play with them some more then  :)
