byuu says: Changelog: - added preliminary WASAPI driver (it's really terrible, though. Patches most welcome.) - all of processor/ updated to auto fn() -> ret syntax - all of gb/ updated to auto fn() -> ret syntax If you want to test the WASAPI driver, then edit ui-tomoko/GNUmakefile, and replace audio.xaudio2 with audio.wasapi Note that the two drivers are incompatible and cannot co-exist (yet. We can probably make it work in the future.) All that's left for the auto fn() -> ret syntax is the NES core and the balanced/performance SNES components. This is kind of a big deal because this syntax change causes diffs between WIPs to go crazy. So the sooner we get this done and out of the way, the better. It's also nice from a consistency standpoint, of course.
