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.


The MAME project as a whole is distributed under the terms of the GNU General Public License, 2 (GPL-2.0), since it contains code made available under multiple GPL-compatible licenses. A great majority of files (over 90% including core files) are under the BSD-3-Clause License and we would encourage new contributors to distribute files under this license.

All Better?

03 Jun 2009

Since the new site went up last year, I've had scattered reports of various problems. Yesterday, I think I managed to sort them out. Turns out most of the problems were caused by an overaggressive filter, which I have now pruned to enable some common folks to access the site. Things that were previously affected include:

  1. Google Reader was unable to view the RSS feed.
  2. MSN/Live/Bing was unable to crawl the site (give it time to start showing up).
  3. Blackberry devices would get errors trying to access the site.

In addition, I noticed that ZTnet had stopped providing the nameservers for, so I switched them over to new ones that point to this site. While I was there I made the canonical site name, and changed all the aliases to redirect there.
