As kid, I loved the Supervision. Though, many people doesn't even ever heard of it. It was the "cheap version" of the GameBoy competitor back in 92.

Could someone port the Supervision emulator "Potator" to the N900?
It uses the SDL library and has good compatibility.

Edit:
There is also a Nintendo DS and a GP2X version of this emulator:
