Quite possibly the most frequently ported game in existence. Versions of it exist on:

Nintendo Entertainment System(NES)
Super Nintendo Entertainment System(SNES)
Nintendo Game Boy
Sega Master System
Sega Game Gear
Sega Genesis
NEC TurboGrafx 16(TG16)

The only contemporary system I am aware of that it is not on is the Atari 7800. Poor schmucks.

I like it!
