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 0.122u5

11 Jan 2008

16 more bugs squashed, and a new update to play with. Have fun!

MAME 0.122u4

07 Jan 2008

A little early, but there has been a ton of activity in the last few days, so now is the right time for an update. What's new? Over 40 MAMETesters bugfixes, for a start! Read about the rest of it in the whatsnew.

Edit: due to an unexplained glitch, I had to break this patch into two pieces. Apply them both. If you already tried to apply the original single patch and failed, then simply applying the second part should give you a working result. Sorry for the inconvenience!

New ROMS from Exidy

03 Jan 2008

Thanks to the very kind generosity of mr H.R. Kaufmann, president of Xidy, now owner of the Exidy trademark, we have been allowed more ROM for free, personal non-commercial use. You can get them in the ROM Page, Targ and Spectar are the new additions, and more to come!

MAME 0.122u3

03 Jan 2008

Getting back on a Thursday schedule after the holidays, it's time for the first update of the new year. Some nice bug fixes included this time, with 14 new MAMETesters bugs fixed in the last couple of days. Have fun!

MAME 0.122u2

30 Dec 2007

Get it hot off the presses at the Latest Updates page!

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!
