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 is available over at the Latest Releases page.
Also, if you check out the Developer Documentation secton, you may notice that I've put up some preliminary documentation on the driver structure. Hopefully over time, others who are familiar with the system will submit some more stuff to add.
The source update to MAME 0.97u2 is now available on the latest releases page.
The first update to version 0.97 is now available on the Latest Releases page.
