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.

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.

Get the latest release here.

MAME 0.104u3

22 Feb 2006

Get it while it's fresh over at the Latest Release page. Some significant changes this time, so be sure to report bugs if you find them.

MAME 0.104u2

16 Feb 2006

Latest updates are now available. It's possible I did something to require the latest tools, though I didn't do it deliberately. If you need an update, just grab the tools here.

Site Updates

11 Feb 2006

A couple of new changes to the site. First is a new section containing links to the Development Tools that are used to build MAME under Windows. This information has been floating around in a readme file, but it's much nicer in this format. Plus, there is now an almost all-in-one package available with all the tools that makes setup much easier. Note that you should hold off using the new tools until the next intermediate release due to a dependence on the header file multimon.h, which I am fixing in u2.

The second change is an update to the eBay Policies to make a few things clearer, specifically emphasizing the cases where referencing MAME in any way makes us very unhappy.

Still more to come in the near future, including a new addition to the ROM Images section (and no, it's not Poly Play!)

MAME 0.104u1

09 Feb 2006

The first update to 0.104 is now available.

Lost submissions

07 Feb 2006

If you've sent any submissions to in the last week, they are likely floating in the ether somewhere. You should switch to sending them to instead. I've fixed the problem that caused the .com-sent ones to not get forwarded, but .org is the way to go in the future.

MAME 0.104, take 2

05 Feb 2006

A last minute bug was found that caused -listxml to crash. If you downloaded the source and it has this crash, I've put up a fixed set of sources (same name).

If you already downloaded the sources and want a quick fix, just grab and apply this diff.
