MESS ( M ultiple E mulator S uper S ystem ), formerly u. a. as a standard snapshot in MESS GUI partly also MESS is an emulator system available since 1998 for many game consoles and computer systems . Since May 2015, MESS has been united with the original MAME project.If you compile your versions yourself from the MAME source code, you can build a leaner version with a focus on computers and consoles, the executable file of which is then named mess (64).


The aim of MESS is to preserve decades of computer and console history despite advancing technological development. MESS is based on the MAME core.

MESS emulates handhelds , game consoles, computers (including mainframes and single-board computers ), as well as pocket calculators, chess computers, etc. The focus of the project (as with MAME ) is on the accuracy of the emulation and platform-independent source code, which is why it is not always the fastest emulator for a particular system. Since May 2015 (version 0.162) both MESS and MAME have been based on the same source code. Both projects have benefited from the merger, as component improvements will benefit both arcade and computer and console emulation.

2199 systems are currently being emulated, 1081 of which are independent (status: Ver. 0.163 from February 25, 2015). The oldest supported system is the Small-Scale Experimental Machine from 1948.

Most systems also require so-called ROM images of the individual operating system files and often also of the storage media used at that time (e.g. diskette images ) . As with many other emulators, these are not included for copyright reasons.


In 2013, the Internet Archive began offering abandonware classic games as a browser- playable emulation via MESS , e.g. B. the Atari 2600 video game ET the Extra-Terrestrial .
