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.

MAME 0.139u4

14 Oct 2010

One more MAME Update before we hit 0.140. Please make sure any issues are logged MAMETesters in the next few days to help ensure the upcoming release is solid.

MAME 0.139u3

18 Sep 2010

At last, a new MAME Update! Be sure to report anything fishy at MAMETesters.

MAME 0.139u2

30 Aug 2010

Lots of internal shuffling this time, so please give the latest MAME Update a try and report anything we didn't catch over at MAMETesters.

MAME 0.139u1

11 Aug 2010

Time for the first 'u' update of the 0.139 cycle. Head over to the Source Updates page to grab the latest & greatest.

MAME 0.139

29 Jul 2010

MAME 0.139 is now available, go get it at the Latest Release page.

You may notice the download sizes to be ~1MB larger for the binary releases. This is due to a bit of EXE bloat from the C++ conversion work (which is still in progress), plus the addition of a rather large .sym file. Keep this .sym file next to your executable so that if you encounter any crashes, you will get useful call stacks that you can report over at MAMETesters.

MAME 0.138u4

22 Jul 2010

This is likely the last 'u' update this cycle, so be sure to grab u4 from the Source Updates page and make sure everything is still working as expected.

MAME 0.138u3

06 Jul 2010

Another bunch of internal shuffling this round, but also some new MCU hookups as well, thanks to the decapping effort. Most of the regressions and performance losses from u2 should be fixed now as well. So go grab the u3 update from the Source Updates page.
