Update to v082r33 release. 

byuu says:

Added MMC2, MMC4, VRC4, VRC7 (no audio.)
Split NES audio code up into individual modules.
Fixed libsnes to compile: Themaister, can you please test to make sure
it works? I don't have a libsnes client on my work PC to test it.
Added about / license information to bottom of advanced settings screen
for now (better than nothing, I guess.)
Blocked PPU reads/writes while rendering for now, easier than coming up
with a bus address locking thing :/

I can't seem to fix MMC5 graphics during the intro to Uchuu Keibitai.
Without that, trying to implement vertical-split screen mode doesn't
make sense.

So as far as special audio chips go ...
* VRC6 is completed
* Sunsoft 5B has everything the only game to use it uses, but there are
  more unused channels I'd like to support anyway (they aren't
  documented, though.)
* MMC5 audio unsupported for now
* VRC7 audio unsupported, probably for a long time (hardest audio driver
  of all. More complex than core NES APU.)
* audio PCM games (Moero Pro Yakyuu!) I probably won't ever support
  (they require external WAV packs.)
