Master System:Master System Mods Wiki

The Sega Master System is an 8-bit console from the third generation of video game consoles. Originally released on October 20, 1985 in Japan as the Sega Mark III — the third revision of the SG-1000 — the Sega Master System was later released in North America (September 1986) and Europe (June 1987), and was also released in Korea (April 1989) as the Samsung Gam-Boy and in Brazil (September 1989) by TecToy. It offers backwards compatibility with the full SG-1000 library on Sega Mark III, Japanese Master System and Korean units. A later revision, the Master System II, was released in 1990 in North America and 1991 in the rest of the world. While the console saw very little market share in Japan and North America due to Nintendo's dominance, it saw success in Europe, Korea and Australia, and became a massive sensation in Brazil where a version of the console is still sold today.
