Game Gear: The Core System (Majesco)

The Game Gear is a handheld game console developed and marketed by Sega. It was released in Japan on October 6, 1990, in North America and Europe in April 1991, and in Australia in 1992. The Game Gear was the first handheld console by Sega and competed with Game Boy from Nintendo, Lynx from Atari, TurboExpress from NEC in the fourth generation of video game consoles. Sega rushed the 8-bit Game Gear to market to compete with the Game Boy. It shares much of its hardware with the Master System, and can play Master System games with an adapter. Its hardware is superior to Game Boy, with a full-color backlit screen and a Z80 CPU.
