The background music was always boss.

Sure, but since it was stolen from an Atari ST music studio program/game, you can't really say it came from Cheetahmen.

and stars

The Cheetahmen were the mascots of Active Enterprises, who made one horrible game compilation for the NES and Genesis before vanishing off the face of the earth, but had plans for an entire Cheetahmen media empire including cartoons, toys, and more relevantly an unreleased, stand-alone Cheetahmen game that was equally horrible, but had some surprisingly awesome music, as heard here.

Their press release is amazing, including plans for a "portable" ultra-console that could play every game ever and probably never made it beyond concept art:

And it recently achieved ,000 of a ,000 goal.
Good job, internet!
