In video game parlance, a multicart is a cartridge that contains more than one game. Typically, the separate games are available individually for purchase or were previously available individually. For this reason, collections, anthologies, and compilations are considered multicarts. The desirability of the multicart to consumers is that it provides better value, greater convenience, and more portability than the separate games would provide. The advantage to developers is that it allows two or more smaller games to be sold together for the price of one larger game, and provides an opportunity to repackage and sell older games one more time, often with little or no changes.

The Master System is an 8-bit third-generation home video game console manufactured and developed 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 with graphical capabilities improved over its predecessors. The Master System launched in North America in 1986, followed by Europe in 1987, and then in Brazil and Korea in 1989. A Japanese version of the Master System was also launched in 1987, which features a few enhancements over the export models : a built-in FM audio chip, a rapid-fire switch, and a dedicated port for the 3D glasses. The Master System II, a cheaper model, was released in 1990 in North America, Australasia and Europe.
