Changelog:
- fixed Super Game Boy regression from v096r04 with bottom tile row
flickering
- fixed GB STAT IRQ regression from previous WIP
- Altered Space is now playable
- GBVideoPlayer isn't; but nobody seems to know exactly what weird
hardware quirk that one relies on to work
- ~3-4% speed improvement in SuperFX games by eliminating function<>
callback on register assignments
- most noticeable in Doom in-game; least noticeable on Yoshi's Island
title screen (darn)
- finished GSU core and SuperFX coprocessor code cleanups
- did some more work cleaning up the LR35902 core and GB CPU code
Just a fair warning: don't get your hopes up on these GB
fixes. Cliffhanger now hangs completely (har har), and none of the
other bugs are fixed. We pretty much did all this work just for Altered
Space. So, I hope you like playing Altered Space.
