SuperFW: a custom firmware for Supercard

[sam2895]

Is it not valid if I do it in an emulator, skipping the screen where you name the characters?

U can use emulator save file must be (.sav)

BTW if someone is up for the Japanese translation of the firmware hit me a DM. Ideally someone who's a native speaker ofc.

Hey folks. I've recently got into modding GBs and flashcarts. I have a GBC that works great, and a GBA that works with original carts, but with my flashcart & superFW 0.17 installed I'm finding so many games just crash or don't work correctly. Advanced Wars 2 crashes at menu, Need For Speed Underground dowsn't work. THPS4 black screens after the menu. Racing Gears doesn't work. Loads of others too.

I keep seeing the occasional post about a patch. Do I have to patch all of my games to make them work well?

May I suggest reverting back to v0.16?

Same problems with 0.15, I'll try 0.16 but dunno how much it will help.

I have tested all the game u mentioned they works fine.
1) THPS4 Works fine no problem at all.
2) Racing gear u need to disable In game-menu.
3) NFS underground also works fine.

IT Works ! thank you very much there is a bug with the light but rowe runs with rtc
MarioMon worked too

Hello, could you tell me how you patched MarioMon? I'm having trouble getting it running. I used the online patcher, and set the .patch next to the rom, but i keep getting a white screen.

Thank you!

Hey there! Just a heads up release 0.18 is out.
Mostly addressing some of the complaints on the NDS mode (ie. flashme/passme issues). I think it should work reasonably well now. I would love that those who use SCSFW could give it a try. It's also much faster in NDS mode!
And other than random fixes/improvements we added Korean+Hangul support.

Enjoy!

it wont load any of the crash bandicoot games
patched or unpatched is not different is there a way to fix it?
also i really like this firmware the game speed is better than the original sc firmware and less bugs in games but not just this! the font and ui looks really cool now i can actually read the games!

Checking back in for August of 2025, and damn, I might have to test this on the SuperCard that I have lying around. It hardly works, at least when using the original software. Looks sick.

I have a very old SuperCard SD that I used back when I only had the GBM. I remember I had some slowdowns in some games, like MegaMan Zero and Metroid Zero Mission. After I got a DSlite I just switched to a r4. I'd like to use the GBM again. Installed SuperFW on the SuperCard SD and it works great for the games I've tested, like Donkey Kong Country 2 (thank you for your work davidgf!). I'm wondering though, would it be worth it to buy a Supercard SDMini to maybe gain some extra performance? I know it's cheap, but because of how the mail works in my country, ordering stuff from China is a bit of a pain.

Hello, lately I’ve been having problems playing Mother 3 because the save files don’t stay saved. I tried saving in version 0.14, but after updating the game, the text gets buggy and it doesn't recognize the save from version 0.14. Is there a patched version of this game? Or is it not possible to use direct save?
