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 0.133u2

And it's MAME 0.133u2, this time featuring a new implementation of the Galaxian sound using the discrete sound system thanks to couriersud. Hopefully we're one step closer to finally nailing it.....

MAME 0.133u1

02 Aug 2009

After a bit of a vacation, we now have MAME 0.133u1. The big milestone for this release is the first emulation of a MAME rip-off project within MAME itself, thanks to R. Belmont and MooglyGuy.

Time for the latest full release.

California Extreme 2009 Slides

16 Jul 2009

As promised at my California Extreme talk, I've posted the slides to the deck so that you have access to all the links and info for reference. If you weren't able to attend, feel free to have a look, but keep in mind that I tend not to put everything in the slides. This year at least there was a bit more show & tell to it, so it should at least make some sense.

Regarding last year's talk, hopefully the organizers will post it relatively soon (I've seen the video). I never posted the slides to that one because they are really pretty sparse and not very useful on their own. Once the video is posted I'll include a link to it and the slides (which you'll need because they are not captured in the video).

Have fun!
