What is MAME

MAME is a multi-purpose emulation framework.

MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important "vintage" software from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the software is usable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?). Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its initial focus.


The MAME project as a whole is distributed under the terms of the GNU General Public License, 2 (GPL-2.0), since it contains code made available under multiple GPL-compatible licenses. A great majority of files (over 90% including core files) are under the BSD-3-Clause License and we would encourage new contributors to distribute files under this license.

Regime Change

05 Apr 2011

After 6 years of coordinating the MAME project, it is time for me to step aside and let someone else handle day-to-day management. It has been an honor to helm the project for so long, and even though I won’t be handling the regular releases and top-level coordination anymore, I do hope to continue working on modernizing the core, so we are not left with a half-finished effort.

With this changing of the guard, I am pleased to announce that Angelo Salese (aka Kale) has volunteered to step in and take over coordination of the project going forward. Angelo has done a great job improving many drivers over the years, and I am confident he will be an excellent project leader going forward.
