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.
Guess I blew it with the last update and forgot to initialize an important variable. Oops. Well, it just means that u6 is now available sooner than expected. It's a big update with the last of my planned renaming of core MAME types.
The latest MAME update is now available on the Latest Release page. As mentioned below, it is a diff against 0.99u3, so either reverse your u4 patches or start over from the beginning to build u5.
New update today, mainly to fix the most glaring bugs/omissions that were introduced last time.
And yes, "whinging" is a real word. Look it up.
A big update this time, available on the Latest Release page (note that the link to the ZIP file points offsite to relieve bandwidth).
In an effort to reduce the amount of clutter caused by redundant and obsolete junk in the front-end code, a number of non-essential command line options have been removed. A few other lightly controversial changes have been made as well. Let the whinging commence.
The latest source update is now available on the Latest Releases page.
Note that as of this release, we've decided to allow video-based gambling games to be included with MAME. As a result, a number of new drivers have been added that were previously removed or which were originally developed for AGEMAME.
