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.

MAME 0.99u7

05 Sep 2005

All of the major bugs in the last update should be fixed in the Latest Release. Continue reporting problems on the MAME Testers message board.

MAME 0.99u6

29 Aug 2005

Guess I blew it with the last update and forgot to initialize an important variable. Oops. Well, it just means that u6 is now available sooner than expected. It's a big update with the last of my planned renaming of core MAME types.

MAME 0.99u5

29 Aug 2005

The latest MAME update is now available on the Latest Release page. As mentioned below, it is a diff against 0.99u3, so either reverse your u4 patches or start over from the beginning to build u5.

MAME 0.99u4 removal

28 Aug 2005

I have removed the 0.99u4 update due to a request from Arika. The next update (u5) will be a diff from 0.99u3. If you already patched your source to u4, you will need to either reverse the patch (patch -p0 -R

MAME 0.99u4

24 Aug 2005

New update today, mainly to fix the most glaring bugs/omissions that were introduced last time.

And yes, "whinging" is a real word. Look it up.

MAME 0.99u3

22 Aug 2005

A big update this time, available on the Latest Release page (note that the link to the ZIP file points offsite to relieve bandwidth).

In an effort to reduce the amount of clutter caused by redundant and obsolete junk in the front-end code, a number of non-essential command line options have been removed. A few other lightly controversial changes have been made as well. Let the whinging commence.

MAME 0.99u2

14 Aug 2005

The latest source update is now available on the Latest Releases page.

Note that as of this release, we've decided to allow video-based gambling games to be included with MAME. As a result, a number of new drivers have been added that were previously removed or which were originally developed for AGEMAME.
