I made a guitar hero game for game boy. It is a little broken and there is only 1 song, a slow version of Iron Man by Black Sabbath.

Directional keys to play the guitar.

Alt to enter the game.

Made with GB studio.

I didn't try on the Gameboy, but you can put it on a cartridge and play it. Not sure it will be easier though...
