New release is now available.
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 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.
A new full release of MAME is now available. Beginning with this release, an official debug binary is being posted so that folks who wish to use MAME for examining what's going on in the code can do so without needing to set up for compiling MAME itself.
The new release is finally here. This version adds proper Bubble Bobble MCU support, some impressive Virtua Racing improvements, a working Limenko driver, and other good stuff!
