Gameboy 512KB, 32KB FRAM Flash Cart (Custom boot logo)

$21.00 USD

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 512KB. 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.

Includes a clear reproduction GB cart shell (separately). Looking for other colour cart shells? Check our DMG or GBC high quality cart shell listings.

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.

This cart works on every Gameboy system – GB, MGB, GBC, GBA, GBA SP and the Game Boy Player. It works on the Analogue Pocket but if you enable the custom boot logo, it will show an error. Games that require more than 512KB of ROM won’t work.

Depending on the option you choose it allows only one of these:

  • A custom boot logo which takes 16KB, if your game takes up the full 512KB flash, the last 16KB bank will be overwritten so your game won’t work properly. The custom boot logo works on the DMG (only 05 tested, 03 not working), Pocket, GBC (05, 03) and GBA 40pin. Some 32KB games might not work. The original boot logo will appear on these devices: GBA 32pin, GBA SP and Super Gameboy. Note: If you power off and power on the GB too quickly, the custom boot logo might not be displayed. Seems to affect the DMG the most. Doesn’t boot at all on the Analogue Pocket if the custom boot logo is enabled.
