As of svn 5666, MESS supports DSP3 & DSP4 emulation. Many thanks to Nach and the ZSNES team for the permission to use their code in MAME & MESS.

The code also includes some recent fixes to DSP4 (maybe the same ones mentioned by byuu in his Sep 7th news, but I'm not 100% sure)

While I'm proud of the fact that MESS is the first emulator to include this fix in a public release, it's actually hard to notice because of graphical corruptions which make Top Gear 3000 unplayable. smile

Moreover, we also got permission for the CX4 emulation which will be included soonish and it's working fine. This makes us 3 chips closer to the goal wink
