Info for gamegear

Sega Game Gear (1990)

The Game Gear is the portable version of the Sega Master System, with slightly enhanced
graphics and stereo sound. The Game Gear would compete in a tough market with the Atari
Lynx, the NEC Turbo Express and the industry leader Nintendo Gameboy. With an adaptor you
could play SMS games on the Game Gear. A TV tuner also turned the system into a portable
television set. Game gear featured many of the Sega Standard games, like Sonic the Hedgehog,
Shinobi, Super Monaco GP and Ecco the Dolphin.
