The Game Master is a handheld game console designed to compete with the NintendoGame Boy. In Germany it was marketed by Hartung, while in the UK it was released as the Systema 2000 by already well established maker of cheap LCD games Systema. It was also sold under alternate names in other countries, including Super Game and Game Tronic. The Game Master has a 64 x 64 monochrome LCD screen capable of displaying graphics on par with the Atari 2600.
The design was much like the SegaGame Gear with a D-Pad and 2 action buttons, although another variation, the Game Plus, features a more Game Boy-like design.  The cartridges resemble those used by the Watara Supervision, with the card edge of the cartridge jutted out past the plastic of the cartridge. The Game Master utilizes a 40-pin cartridge port like the Supervision but is not compatible with Supervision games.
