byuu says:
- bsnes: allow video filtering even when the emulator is paused
- bsnes: improve overscan masking, especially with HD mode 7
- bsnes: improve snow support, especially with HD mode 7
- bsnes: replace real-time cheat code replace with per-frame replace
(ala Pro Action Replay, Snes9X)
- bsnes: treat the latter step() half of CPU::read() calls as idle
cycles
- bsnes: templatize step() where possible (not always practical)
- bsnes: removed Natural<T> templates from key portions of the fast
PPU renderer
- bsnes: dethreaded peripherals (controllers and expansion port
devices)
- bsnes: above optimizations result in a ~20-25% speedup over v107.4
with no accuracy loss
Note that light guns aren't going to work for now, I'll have to fix them
before we can release v108.
