MAME 0.279 is here at last! Building on the work in recent releases, this month you’ll get to see proper lighting and fixes for logic bugs in Sega Model 2 games. Philips CD-i emulation keeps improving as well, including better cursor behaviour and XA audio fixes this month. While we’re talking about things you can see, MAME now emulates the “snow” effect on early ZX Spectrum models caused by memory refresh cycles interfering with video RAM accesses. Graphical issues in various Konami and Irem games have been fixed, and there are noticeable improvements to graphics in some Namco System 23 games.

There’s been more work this month on support for NES-inspired chips from V.R. Technology, bringing some of these low-cost games closer to working. There are lots of improvements for emulated Macs, particularly the PowerBook Duo sub-notebooks, and fixes for a few issues with the Apple IIgs as well. The Casio FZ-1 and related sampling synthesisers now have preliminary sound output. The Sharp MZ-5500 computers are also starting to show some life, although emulation is far from complete.

As always, you can read about everything that changed this month in the whatsnew.txt file, and source code and 64-bit Windows binary packages are available from the download page.
