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 0.106u5

08 Jun 2006

Another release is now available at the releases page. This one is a bit experimental again in that multiple threads are now being used. I'd especially like your testing if you have a hyperthreaded or dual core machine to see how the system behaves. There is definitely some more tweaking needed in the unthrottled case, but normal execution should be fine.

MAME 0.106u4

05 Jun 2006

A new update has been posted. This should fix most of the issues introduced in the last one. Continue to provide feedback on the various MAME boards and blogs. If you're interested in trying it out but don't have the time to compile, look for a precompiled build at my blog in a little bit.

MAME 0.106u3

01 Jun 2006

A new update is now available. Please take special note of the warnings this time:

WARNING: As of this build, the new rendering system is enabled by default. The primary focus at this point is compatibility, not performance. Compared to the old -ddraw system, it will appear slower when fully unthrottled because there is not a good mechanism to skip the render if the graphics hardware is still busy like we used to do. If you have any trouble getting a correct display or if you get warning messages printed out when starting MAME, please post about them on http://mametesters.org.

SECONDARY WARNING: The command line and INI parsing code was rewritten. If you notice any problems with handling of parameters in either case, please report the bugs on http://mametesters.org.

MAME 0.106u2

25 May 2006

Well, here it is: the long-awaited video update in MAME 0.106u2. A few important notes about this release.

First, the new video system is not enabled by default. To enable it, you need to enable the NEW_RENDER makefile flag and recompile the entire project.

Second, if you previously configured MAME to use DirectDraw (which was the previous default), then you will get software-only rendering by default. You need to explicitly enable Direct3D rendering (-d3d) in order to get hardware acceleration. Software rendering is not very fast, especially at high resolutions.

MAME 0.106u1

18 May 2006

The first update to MAME 0.106 is now available. Please take special note of the warning at the top of the whatsnew file. Things are likely to be in flux and unstable for a while, so if you are looking for solid, everything works releases, stick to the full 0.106 release.

MAME 0.106

13 May 2006

MAME 0.106 has now officially been released. Download it from the releases page.

MAME 0.105u5

11 May 2006

One more intermediate update to 0.105 is now available.
