Welcome to The Official Site of the MAME Development Team

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.
Please note that MAME is a registered trademark of Gregory Ember, and permission is required to use the "MAME" name, logo or wordmark.

MAME 0.122u1

23 Dec 2007

As a little pre-Christmas treat, we have the first update to MAME 0.122 posted at the Source Updates page. The big news here is a working driver for the upright Buggy Boy, thanks to Philip Bennett. Haze and Dox have been busy cleaning up the afega and nmk16 drivers, and as a result a large number of previously non-working games are now working. In addition to the Buggy Boy work, Philip also submitted a nice fix to the Namco NA1 sound which improves the results substantially.

Happy holidays!

MAME 0.122

18 Dec 2007

It's late, so I'll make it short: MAME 0.122 has been published. Download it. Check out the whatsnew. Report bugs at MAMETesters. Good night!

Small Changes

15 Dec 2007

There have been a couple of small changes to the way file downloads are handled on this site. Source Updates, which are still on their own page, will continue to be hosted here directly. However, for larger files, it is becoming necessary to rely on mirror sites to keep under bandwidth limitations. In order to facilitate this, the Latest Release and Previous Releases pages now select a mirror at random when you click the Download link. Depending on the mirror site, this may be either a direct link to the file, or in some case might require a redirect to the mirror site where the download will auto-initiate after a few seconds.

While we all definitely prefer a simpler mechanism, this one seems a good compromise given current realities.

Another change you probably won't notice is that the Source Updates, Latest Release, and Source Code Browser pages are all now auto-generated based on which files are on the server. This certainly makes my life a little easier.

Special thanks to s_bastian and Twisty for help with the backend coding!

MAME 0.121u4

13 Dec 2007

A new update to MAME 0.121 has been posted. With this update we now have support for a number of new and rare Namco System 12 games (not all working), some nice new SCSP updates, improved Star Wars accuracy, and a mostly working Mortal Kombat 4. We're nearing the end of the 0.122 development cycle, so be sure to report any significant bugs over at MAMETesters. Thanks!

MAME 0.121u3

06 Dec 2007

Time for a new update. Grab it from the Source Updates page. Some nice SCSP improvements this time around from kingshriek, another big dkong driver update from couriersud, and the usual collection of internal cleanups. Full details in the whatsnew file.

Also, I'd like to announce that I've found a couple of volunteers to help keep the site running smoothly. I'll let them introduce themselves when they are ready, but things are already progressing behind the scenes. I'm also looking for help with keeping the wiki up to date and adding content. If you are interested in helping out there, please contact me and let me know what you'd like to help with.

New Server

01 Dec 2007

After the hiccups of the past few weeks, I've switched this site over to a new server. I had to do a lot more manual configuration on this side, so if anything is not working, please email the webmaster.

MAME 0.121u1

22 Nov 2007

A quick turnaround for this update, mainly to address a few lingering bugs in the official 0.121 release. Grab it from the new Source Updates page. Happy Thanksgiving (if that means anything in your part of the world)!
