The Sega Master System (SMS) is a third-generation home video game console manufactured by Sega. It was originally a remodeled export version of the Sega Mark III, the third iteration of the SG-1000 series of consoles, which was released in Japan in 1985 and featured enhanced graphical capabilities over its predecessors. The Master System launched in North America in 1986, followed by Europe in 1987, and Brazil in 1989. A Japanese version of the Master System was also launched in 1987, which has additional features over the Mark III and other regional variants of the console, namely a built-in FM audio chip, a rapid-fire switch and a dedicated port for the 3D glasses. A cost-reduced model known as the Master System II was released in 1990 in North America and Europe.
