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.
Get it while it's hot over on the Source Updates page. It's worth pointing out that the cheat system is re-enabled with this version, but it is in read-only mode (that is, it can read new-format cheats but has no tools to generate new ones yet). Until there is a converted database, the code is still very much in the early test phase, so don't get too excited just yet. With luck, we'll have cheats working again in an update or two.
Time for a massive update: MAME 0.126u3. Due to a change internally with the way memory regions are handled, a large percentage of all files in the project needed to be updated.
There's been a regression test against the change already, so we should be beyond crashing problems. But it is possible that some games may be missing sound due to mismatched sound regions. If you hear anything funky, please report it to MAMETesters so that we can get the problems ironed out in time for u4.
The first update of the MAME 0.127 development cycle is now available. Please make note of the fact that the cheat engine is under serious construction right now and has been disabled.
At last, it is time for a full MAME update: grab MAME 0.126 from the Latest Release page.
