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.

Thanks to everyone that contacted us regarding licenses for their part of project
we have managed to cover more then 96% of source to be under some of open source license.
We are still in the process of contacting past contributors in order to sort this out.
If you have contributed and we have not contacted you yet, please contact us

Note that output XML is changed so rom managers and frontends need to get updated too.

MAME is going open source

20 May 2015

After lot of years being under MAME own license (prohibiting any commercial use) and therefore not open source, we are finally moving towards becoming officially open source project. Idea is to keep core under BSD3 license and rest is up to developers that created code (drivers and devices emulation). (options are BSD3, LGPL2 or GPL2)

Hopefully this will bring more new developers to MAME project and give more life to project itself.

Please note that MAME trademark is still valid the "MAME" name and MAME logo may not be used without first obtaining permission of the trademark holder.
