Gameboy 1MB 32KB FRAM Mini Flash Cart (fits in a GBA cartridge, Ultra low power, Custom boot logo option)

This is a unique Gameboy flash cart which fits inside a GBA repo cartridge so you can play on the GBA and GBA SP without the cartridge sticking out like it does for a regular Gameboy cartridge. Because of that, this cart will only work in the GBA, GBA SP and the Game Boy Player. The GBA repo cart will need to trigger GB mode – we did this with a bit of hot glue on the bottom left side.

This re-programmable Flash Cartridge is MBC5 only which allows you to play most of the later released Gameboy/Gameboy Colour games including some of the Pokemon games (no RTC support), Zelda DX, LSDJ (only 1 song), etc and allows you to re-flash it with any flasher like GBxCart RW that supports the MX29F800C.

Works with GB Studio v1.1.0+ with saving if you wish to develop your own game. 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 most MBC3 games should work and some MBC1 games may work.

Special options:
– Custom boot logo which takes 16KB, if your game takes up the full 1MB flash, the last 16KB bank will be overwritten. The custom boot logo works on the GBA 40pin. The original boot logo will appear on these devices: GBA 32pin and GBA SP. Just bridge the far left jumper with solder, you may need to use a little wire.
– 8KB RAM locking useful for MBC1 games like Donkey Kong Country 3. Just bridge the far right jumper with solder.

This cart only fits properly in the GBA, GBA SP and the Game Boy Player. If you can fit it on a DMG, MGB or GBC then it will work too but it won’t fit using the GBA cartridge shell. Games that require more than 1MB of ROM won’t work.

Comes in a generic clear or grey Gameboy cartridge. Each unit is assembled in house and is tested on a Gameboy Advance. You can supply the ROM file for us to flash the cart if you like, it will be tested for 20-30 seconds to ensure it works.
