This cart only fits properly in the GBA, GBA SP and the Game Boy Player. If you can fit it in 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.
Each unit is assembled in house and is tested on a Gameboy Advance.
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.
– 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.
ROM: 1MB Flash
MBC: MBC5 (with ROM banking range 0x2000 – 0x3000 to allow for some MBC3/1 games)
Most MBC3 games should work.
MBC1 games that won’t work: Any that needs 32KB RAM or requires more than 512KB of ROM.
The PCB finish is ENIG.
