What's the difference?

[Final Frag]

Are M.E.S.S. and M.A.M.E. the same emulators or are they different.

[montpics]

No, they are different to one another.

Taken from Wikipedia :

MAME :

MAME is an emulator application designed to recreate the hardware of arcade game systems in software, with the intent of preserving gaming history and preventing vintage games from being lost or forgotten. The name is an acronym for Multiple Arcade Machine Emulator.

MESS :

MESS (Multiple Emulator Super System) is an emulator for many game consoles and computer systems, based on the MAME core.

The primary purpose of MESS is to preserve decades of computer and console history. As technology continues to progress, MESS prevents these vintage systems from being lost and forgotten.

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, for example on the Atari 7800.[1]

MESS supports 154 unique systems with 445 total system variations and is growing all the time. However, not all of the systems in MESS are functional: 111 of them are marked as not working in the current version.

And MESS is based on the mame source code which is why it shares a version number with MAME and updates in parallel releases.
