Update to v095r08 release. 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.

auto uPD96050::readSR() -> uint8 {
Update to v074 release. byuu says (since v073): This release adds full low-level emulation of the NEC uPD96050 coprocessor, used by the ST-0010 (F1 Race of Champions II) and the ST-0011 (Hayazashi Nidan Morita Shougi). The former was already playable with HLE, but lacked timing emulation. The latter has never been playable through emulation before now. But as with SD Gundam GX before, you really weren't missing much. [...] Also new in this release is my own Game Boy emulator. It is being used to provide native Super Game Boy support, built directly into bsnes. This core is released under the GPLv2, but I am willing to grant a more permissive license for other SNES emulators, if anyone is interested. Of course I cannot compete with the quality of gambatte, and certainly not from only a weeks' worth of work. Currently, there is no Game Boy-side sound output and there are quite a few bugs remaining in its emulation core. I would appreciate any help on this, the Game Boy is not my forte. So yes, we are taking a step back today, so that we may take two steps forward in the future. [...] Lastly, the debugger is still Linux-only, but it is now stable enough to be considered usable. Check it out if you like, compile with -DDEBUGGER to enable it.
