MESS (short for Multi Emulator Super System) is a suite of emulators for a variety of computers and game consoles. Formerly a sister project, it is now a part of the Arcade Game emulator MAME.
The list of emulated systems is too extensive to include here, but as of MAME version 0.181 it covers 1060 unique systems, with the emulation in various stages of development ranging from barely started (more recent or obscure systems) to virtually perfect (older or well-known systems).
Like MAME, MESS focused on accuracy rather than speed with the overall goal of preserving computing history. Before the merger, where the two projects have emulated hardware in common, it'll be implemented in MAME first, then filter through to MESS the next time the developers synchronise the shared branches of the source tree.
