Mame32

Play the games from the arcades on a regular PC. The utility creates an environment to launch the original version of classic games available on standalone machines produced from 1978 to 2000. The suite is not an emulator and recreates the older game versions not normally available on modern systems.

Mame32 is an emulator. Simply put, it enables a standard PC to mimic the internal hardware of a large number of stand alone arcade machines from 1978 to 2000.
When you play a game with the emulator, you're not playing a recreation of the original arcade hit, when you play the games with the emulator .
You're running the exact same software that was written for a Z80 microprocessor almost twenty years ago
