Wario Land 3 is a bootlegged game for the Sega Genesis (also known as the Mega Drive) that is, in actuality, a hack of Puggsy, which was a popular platforming game for the Sega Genesis that included an interesting anti-piracy feature.
Differences
Nothing really that significant has been changed from the original game; it seems that Puggsy himself has been converted to a disgusting bootlegged sprite of Wario and the title screen has changed. Not much is known about this game.
