N64 memory card non-volatile mod

[stuntpenguin007]

WTF? Why did all the words "m.o.d" get changed to "romance"?

It could be for April fools day

edit:
mod = mo(d)
nintendo = nintend(o)
portable = portabl(e)
hack = hac(k)

NICE. I'd be interested. I was also thinking of doing this with a Pokemon game if it's feasible. I could probably send a copy your way if you think you can get something working (maybe a little discount on the N64 pack?).

This.

PM me.

N64 memory packs that don't die? I'd buy a few of those for sure.

Wow this thread is old

I found a nonvolatile fram chip I could use for this that has the exact same footprint as the existing sram. In other words, there's a way to do this without etching a custom board, although it will only have one bank of memory. I'll be testing it out on a pokemon cartridge soon.

actually, do you think you could fit your tiny rumble into a controller pack??

You mean you could just swap the original one out for this one? Can you share the chips name/modelnumber?

If you can make this work on gbc games ill send you like 50 games to do this to. lower price in bulk? let me know if you can put it for all games i had a great save on my crystal then one day my whole game gone!

[lucidPerspective]

I need the name of the fram chip, modding my gameboy games with them would be awesome!

[e3c]

Please i want to do it. one for a n64p and another for gbc games please let me know

[CidC]

Yes, I see this as a great way to put non-volatile memory inside a n64p. Only use the controller pack's chip, solder the necessary connections to the controller's board, and no worries about saving to the N64p. In that case, having the extra 3 banks would help.

[e3c]

yeah though anyone know if for sure if it works on gbc games? i would love to play games without worrying about my save being lost

[lucidPerspective]

There's some testing being done be a cool individual It's not as easy as was first thought, you need to regulate the correct voltage from inside of the cartridge, for when it reads and writes. and so that you don't fry the chip

[evilteddy]

That doesn't seem right. The gameboy colour runs on 3.3V for the CPU and accessing the cart so any sram (or fram) chip should work fine without any voltage conversion.

[e3c]

well how lon will it take i got over 100 gbc cames that are ready for modding. also how much would they be for gbc and for over 50 bulk?

Mine just came in the mail today. I soldered it into my copy of pokemon gold, but it didn't work. Then it occurred to me that even though it doesn't need a battery to hold gamesaves, I still need to provide it with 2V - 3.6V in order to read or write it. So I busted out my multimeter to see if any voltage was being supplied, and I found out it was being supplied with around 5.5V.

Also e3c, what exactly are you asking? are you wanting someone to mod 100 gbc games with this mod for you? that wouldn't be cheap, I'm not exactly sure, but I'm guessing the cost of just parts per cartridge would be around $10 ..then the cost of paying someone to do it.
