Gameboy 4MB 32KB FRAM Mini Flash Cart (fits in a GBA cartridge) [Coming soon]

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.

Waiting on 4MB flash chips – expected by the end of May.

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 MBM29F033C chip via the audio pin method.

Because the audio pin method is used this means that any rom that tries to erase/write to the flash chip won’t work, for example, LittleFM won’t work.

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.

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. Games that require more than 4MB 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.
