MAME stands for Multiple Arcade Machine Emulator. When used in conjunction with an arcade game's data files (ROMs), MAME will more or less faithfully reproduce that game on a PC. The ROM images that MAME utilizes are "dumped" from arcade games' original circuit-board ROM chips. MAME becomes the "hardware" for the games, taking the place of their original CPUs and support chips. Therefore, these games are NOT simulations, but the actual, original games that appeared in arcades.
In order to run this emulator you must have Yellow Dog Linux installed on your PlayStation 3.
