The Multiple Arcade Machine Emulator - MAME

 A software emulator of several arcade games from the past.
 .
 MAME stands for Multiple Arcade Machine Emulator. When used
 in conjunction with images of the original arcade game's ROM
 and disk data, MAME attempts to reproduce that game as faithfully
 as possible on a more modern general-purpose computer. MAME can
 currently emulate several thousand different classic arcade video
 games from the late 1970s through the modern era.
