Hey guys,
I was wondering...IS there a way to reprogram a gameboy colour cartridge with another game?
Thank you in advance.
EDIT:
Never mind, some hard research paid off. For future reference though if anyone else comes across the same problem.
To build the programmer:
Manual: http://www.reinerziegler.de/GB-Flasher/gbcflsh_manual.pdf (http://www.reinerziegler.de/GB-Flasher/gbcflsh_manual.pdf)
Schematics: http://www.reinerziegler.de/GB-Flasher/schem+pcb/GB%20Cart%20Flasher%20%28USB%29.pdf (http://www.reinerziegler.de/GB-Flasher/schem+pcb/GB%20Cart%20Flasher%20%28USB%29.pdf)
Components needed:
R1: 27R
R2: 27R
R3: 1k5
R4: 470R
R5: 330R
R6: 330R
C1: 100u
C2: 100n
C3: 100n
C4: 100n
C5: 100n
C6: 33n
C7: 27p
C8: 27p
L1: ~10uH
X1: 6Mhz
D1: Green
D2: Red
IC1: FTDI FT232BM
IC2: ATMEGA 8515
Now because all commercial cartridges are ROM, you will have to replace the chip with a flashable one (29F032B)

Nice post, I've always liked gbc mods/custom roms the best. I was wondering though, after your researching for the flasher, did you find out how big a game could possibly be?
I've always wanted to make a massive pokemon game that spanned through much more than just 2 regions like gsc did, but I've never been sure whether it was even possible or not. I've messed around with making ruby rom hacks before, but If a gbc could run a cartridge with huge amounts of data then I would probably start learning how to make gbc pokemon rom hacks.
Any light on the subject would be appreciated, thanks.

Dude thats pretty sick. I thought that game cartridges are not re-programmable? Read only memory?

Correct, thats why if you look up, there will be a guide on how to replace the ROM chip with a flashable one.

If you read the guide on how to make a programmable cartridge you will see he used a previous Zelda game which has 32K of RAM. The author states with that much RAM you can pretty much program any game onto it. Heres a list on which cartridges contain what RAM and Chips:

As you can see, its a complete :censored: to do especially if you want to tinker with custom ROM's on a larger scale. This is where I'd like the R&D team to step in and make clean flashable cartridges instead of having to play lottery every time you buy one from a garage sale hoping it has the right RAM size etc inside.
