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.
I've recently been in contact with Duncan Brown, the guy who wrote Alien Arena, which was recently added to MAME. Alien Arena was an entirely new game (in 1985) that was designed to run on the classic Williams hardware. Duncan owned an arcade at that time, and he actually put the game on location there with the hopes of making it into a more widely distributed conversion kit for arcade operators.
Duncan has been kind enough to allow us to make his game available free for non-commercial use, just like the other games in the ROM Images section. So I invite you to check it out, read more about the history of the game, and enjoy playing something new. Duncan has even provided his email address in the enclosed readme, so feel free to drop him and line and let him know what you thought about it!
A couple of new changes to the site. First is a new section containing links to the Development Tools that are used to build MAME under Windows. This information has been floating around in a readme file, but it's much nicer in this format. Plus, there is now an almost all-in-one package available with all the tools that makes setup much easier. Note that you should hold off using the new tools until the next intermediate release due to a dependence on the header file multimon.h, which I am fixing in u2.
The second change is an update to the eBay Policies to make a few things clearer, specifically emphasizing the cases where referencing MAME in any way makes us very unhappy.
Still more to come in the near future, including a new addition to the ROM Images section (and no, it's not Poly Play!)
