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