MasterSystem

The Sega Master System is a third-generation home video game console manufactured by Sega. Released in Japan as the SG-1000 Mark III in 1985, it was rebranded and released as the Master System in North America and Europe in 1986. The Master System was Sega's first attempt to compete with Nintendo's Famicom and the Atari 7800.

The console featured a Z80 microprocessor and a Yamaha FM synthesis chip for sound. It supported two types of game media: ROM cartridges and the Sega Card, a credit-card sized memory card. Notable games for the Master System include Alex Kidd in Miracle World, Phantasy Star, and Wonder Boy. While it achieved moderate success in Europe and Brazil, it struggled to gain significant market share in North America and Japan against the dominance of Nintendo.

Despite its limited commercial success in certain regions, the Master System is remembered for its innovative features for the time, such as the Game Genie accessory which allowed players to cheat, and its strong library of role-playing games. It was succeeded by the Sega Genesis in 1988.
