Gameboy 256KB, 32KB FRAM Flash Cart


This re-programmable Flash Cartridge is MBC5 only which allows you to play some of the later released Gameboy/Gameboy Colour games if they are under 256KB. This cart could be useful if you are making a GB Studio game as it allows for a custom boot logo and supports saving too. Designed and made in Australia.

Need to flash a game on this cart? Make sure to grab our GBxCart Flasher.

Comes in a clear reproduction GB cart shell (or a clear black if we run out of clear) and our label (separately for you to apply). Looking for other colour cart shells? Check our GB or GBC cart shell listing.

Works with GB Studio v1.1.0+ with saving if you wish to develop your own game but with a 512KB size limit. Check this list of Gameboy games to see the ROM/RAM size and MBC type your game will have, you would be looking for MBC5 games but some MBC1/3 may work.
