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 0.123u4

06 Mar 2008

A new update to MAME 0.123 is now available on the Source Updates page. A few big changes lurk in this update, so please give your favorite games a whirl to make sure we sift out any bugs before we start closing in on 0.124! Report what you find over at the new MAMETesters bug database.

MAME 0.123u3

27 Feb 2008

Time for another update to MAME 0.123. Read the whatsnew file for a full rundown of what's changed.

Also, thanks to Fujix's hard work over at MAMETesters, they will shortly be unveiling a new bug database to track issues in. This will allow for more distributed tracking and will hopefully make it easier to sift through the piles of bugs going forward.

MAME 0.123u2

MAME 0.123

05 Feb 2008

Most of the glitches in 0.122u8 should be taken care of, so it's time to salute MAME's 11th birthday with a nice new release.

(Apologies in advance for the cut-off text in the whatsnew; it should read "Fixed incorrect default screen size in midyunit games." It wasn't a big enough error to prompt a recall!)

Quick 0.122u8 fix

04 Feb 2008

Seems that 0.122u8 went out with a little typo I introduced. Here's a quick fix for it. Please stop the carnage at MAMETesters and report any further issues found once this patch is applied....

MAME 0.122u8

02 Feb 2008

The last update before 0.123 is now available. A few new bug fixes and a lot of nice cleanups of older drivers in this round.
