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 0.109u1

06 Oct 2006

The first update in the 0.110 development cycle is now posted. Some nice new additions and another one of my substantial rewrites are included this time around.

MAME 0.109

26 Sep 2006

It's about time for a new full release. Grab it from the releases page.

MAME 0.108u5

21 Sep 2006

One more 'u' update for 0.108. Lots of big changes in this one, including an Atari vector rewrite, ST-V improvements, N64-based games improvements, and some nice improvements to some of the older trivia and poker games. Note that I rewrote the PNG handling code, so if you find any problems with artwork loading or snapshot saving, be sure to report them to MAME Testers. (Note the alternate link, which is temporary until we get the domain issues sorted out.)

MAME 0.108u4

14 Sep 2006

A new update is now available. There's been some mucking in the core again, so be on the lookout for incorrect colors in case something got tweaked along the way. As usual, report anything you find to MAME Testers.

MAME 0.108u3

07 Sep 2006

New release is now available.

MAME 0.108u2

31 Aug 2006

A new release of MAME is now available. If you want to play with multithreading again, it is now a runtime option you can control with a command line option. Also, probably the most explicit arcade game to date has been added, and a bunch of Lethal Enforcers clones have been unearthed.

MAME 0.108u1

24 Aug 2006

The first 'u' release of 0.108 is now available. Biggest change this time is a major NES PPU rewrite courtesy of Brad Oliver. Should improve the accuracy of the NES-based games; report anything odd or broken at MAMETesters.
