It’s the end of another month, which means it’s time for another MAME release! As you’d expect, MAME 0.287 includes a wide-ranging array of emulation improvements to a multitude of systems. Interesting changes this month include better Namco System 23 graphics, improved lighting for Sega Model 3, and software-controlled volume control/panning for Philips CD-i (along with improved stability).

The GRiD Compass family has received a keyboard overhaul as well as an initial DAC sound output implementation. The Apple II family now handles tricky raster effects more realistically, as well as getting a substantial software list update (metadata for the MECC collection is in much better shape). And speaking of software lists, a couple of NES prototypes have been added.

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