Gijs] cracked open his Game Boy and added some parts to give him more sound synthesis control. He uses Little Sound Dj (LSDj), a popular Game Boy program used to pump out those classic 8-bit sounds. The unit seen above and heard in the clip after the break has an added potentiometer and circuit board. He’s got a few other hacked Game Boys on his site as well, including an Arduino generating random music on the handheld.
