Just got 2 Gameboy (DMG-01)

Just got 2 DMG-01 for a few CHF .. good deal.
I know a few friends who  like and do some chipmusic, so why not add some mod to the gameboy and give it for testing to chipmusic friends.

Mod planned :
- Backlight
- Pro sound
- Super gameboy CPU transplant (great for live act. ultra fast boot and no kling)
- maybe integrate a midi input inside the gameboy
- idea for a distortion inside ..
- some paint job (pimp my DMG)
