Game Master is a cartridge based console that was originally released in 1990 from the German company Hartung but later it was released under various names. Some of the names of these models are: Systema 2000 (United Kingdom), Videojet Game Master (France), Hartung Game Tronic (France), Hartung Super Game (France).
Game Master is actually a cheap effort to compete with Game Boy, while a lot of companies wanted a slice of the pie in the handheld market. The 64x64 LCD screen is monochromatic since it could display only white and black pixels. It has also a power switch and supports volume and contrast adjustment. The player could listen to the sound from a built-in speaker or use the headphone jack, since the box includes small stereo headphones. The power supply can be four AA batteries or a 6V DC external power source.
