MAME (an acronym of Multiple Arcade Machine Emulator) is an emulator application designed to recreate the hardware of arcade game systems in software on modern personal computers and other platforms. The intention is to preserve gaming history by preventing vintage games from being lost or forgotten. The aim of MAME is to be a reference to the inner workings of the emulated arcade machines; the ability to actually play the games is considered "a nice side effect".

The first public MAME release (0.1) was on February 5, 1997, by Nicola Salmoria. The emulator now supports over seven thousand unique games and ten thousand actual ROM image sets, though not all of the supported games are playable.

Multi Emulator Super System (MESS) is an emulator for many game consoles and computer systems, based on the MAME core. MESS emulates portable and console gaming systems, computer platforms, and calculators. The project strives for accuracy and portability and therefore is not always the fastest emulator for any one particular system. However, its accuracy makes it useful for homebrew game development.

MESS supports 668 unique systems with 1748 total system variations
