From the project
A collection of my Game Boy cartridge circuit board designs
This is a slightly updated design of my original flashable MBC3-based multicart for the Game Boy. You can make a 2-in-1 or 4-in-1 cartridge, that changes games based on a button press or power cycling the Game Boy. With this board you can also make a single game, but with the addition of a pressable reset button on the cartridge.
This MBC3 cartridge uses new old stock 29F033 EEPROM chips and battery-backed SRAM.
