Nintendo Gameboy DMG-01
Modified Nintendo Gameboy DMG-01 with Gameboy Camera. I've added the Getlofi.com LTC1799 Precision Oscillator used to control the range of pitch.
I've also modified it with pro-sound for quality stereo output, onboard speaker
is still intact and works.
These modified Gameboys work as normal until adjust the pitch control.
You can still play all of your favorite games. The pitch control give powerful control when using the Gameboy as a synthesizer.
