Now available for download is the first update to MAME 0.112. And this one's a big one. The most obvious impact is that the source code tree has been significantly reorganized. A number of changes that have been made over the past couple of years have resulted in a somewhat more modular codebase, and now is a good time to organize things accordingly. Unfortunately, due to the file movement, a diff of this release would probably be twice the size of the raw code, so you'll have to download the full set of sources.

If you are a developer, it is very important that you update to this release, as patches against 0.112 and earlier won't apply properly, and there is no guarantee that they will be accepted.

Other exciting news for this release includes actual emulation of the Namco 54xx sound chip, which turns out to be a Fujitsu MB8844 microcontroller with embedded ROM. This allows the removal of samples from Galaga, Bosconian, and Xevious, among others. We also have some nice sound core improvements from the hoot development team, some nice new input port support, a few new CPS2 keys, and a bunch of fixes for subtly (and not-so-subtly) broken drivers due to the Z80 change late in the 0.111 dev cycle. Have fun!
