The open hardware GB/GBC cartridge system

Squareboi is an open hardware cartridge system for the Game Boy Color, made to be as accessible and DIY-friendly as possible. Using a handful of off-the-shelf components, it provides the same functionality as an original cartridge, compatible with the majority of programs. Additionally, an Arduino-based programmer allows for easy transfer of games and save data.
