GB-303 Cartridge for Arduinoboy!

GB303 MIDI is a re-imagining of GB303; a now abandoned chiptune Gameboy cartridge from the mid-2010’s that had knobs poking out the top.

It recreates some of the sound of the Roland TB303 in a bitcrushed chiptune style. GB303 MIDI enables full MIDI control over the previously limited cartridge, as well as ease of use letting you load the rom onto any Gameboy compatible cartridge.

Play it with a MIDI keyboard using an Arduinoboy adapter. Arduinoboy should be set to mGB mode.
