The Game Master (also known as Systema 2000, Super Game, Game Tronic, and Game Plus) is a handheld released in the early 90s by the obscure German company Hartung, as well as others in Europe and Asia under license. It tried to front the Game Boy, and since you've probably never heard of it, you can guess how that ended.
