A collection of my Game Boy cartridge circuit board designs

This is an updated design of my flashable MBC5-based cartridge for the Game Boy. The MBC5 mapper greatly augments the memory access of the Game Boy for larger games. Most of the games that came out in the last years of the Game Boy and Game Boy Color used the MBC5 mapper.

This MBC5 cartridge uses brand new M29F160 EEPROM chips and battery-backed SRAM.

This circuit board should cover most MBC5 games. The features are as follows:
