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


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.

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.

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, Pocket, GBC (05, 03) and GBA 40pin. The original boot logo will appear on these devices: GBA 32pin, GBA SP and Super Gameboy.
