Ms. Pac-Man is a 1981 arcade game developed by Midway Manufacturing as an unlicensed modification of the original Pac-Man, before being taken by Namco as an official game. Its success caused the game to be ported to a plethora of platforms, including the Sega Mega Drive and Sega Master System in 1991 and the Sega Game Gear in 1993.
The Sega ports of Ms. Pac-Man can be confusing. Tengen originally brought the game to the Mega Drive in North America and the Master System in 1991, but four years later the game was brought to European Mega Drives by the successor to Tengen, Time Warner Interactive (although the ROM still credits Tengen). The Game Gear port was handled in-house by Namco and was released twice – initially in 1993, and then re-released by Majesco Sales in 2000.
