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 0.141u4

25 Mar 2011

At last, MAME 0.141u3 is now posted to the Latest Updates page. The megatech.xml hash file included here is intended to be placed in a "hash" directory next to the MAME executable. We are still working to resolve how this will play out in the final 0.142 release, which you can expect to see appear in a week or so if all goes according to plan.

Happy New Year! Well, not yet here on Pacific Time, so technically MAME 0.141 is the last MAME release of 2010, and not the first release of 2011. Have fun!

The final update of the 0.140 dev cycle is now available on the Latest Updates page. Assuming nothing exciting happens, expect 0.141 before the end of the year.
