0.27 SPC: More optimizations SPC: Completely rewrote SPC timers - fixes some SPC problems and sound playing too fast or slow SPC: Forcing SPC to 'catch up' once per 65816 'scanline' time period, may clear up more sound quirks (until sound generation code can be rewritten) Timing: Vblank timing adjusted slightly Timing: Hblank timing code simplified (actually done in 0.26!)
