Gameboy 32KBx15 Flash Cart


This re-programmable flash cartridge allows you to store 15 x 32KB games that don’t need an MBC or saves. The first 32KB is used for the loader which is used to select the game at start up. Writing to the cart only works with GBxCart RW using the dedicated program shown below. Designed and made in Australia.

This cart works on every Gameboy system – GB, MGB, GBC, GBA, GBA SP and the Game Boy Player. Games that require more than 32KB of ROM won’t work.
