Savestates are compressed now and a serious bug was found/fixed, which should make any new saves much more reliable, if not perfect, while using half the space or less. Also, FMV audio lag is fixed (using new Forced XA Updates=auto setting).
A problem we didn't have time to fix: if a savestate used a different BIOS setting (HLE vs BIOS), the savestate menu will not load it. In next release, it will warn you and do its best to load it anyway, sorry about that.
Note regarding new frameskip option: Frameskip does a good job of letting slower games run at full speed, but it can introduce graphics glitches in some games, despite being intelligent about deciding when to frameskip by monitoring VRAM accesses. That is why it is off by default.
Short-term goals: IPU HW scaling, SW scaling fixes, memcard manager, flexible controls + analog stick support, cheat support.
Long-term goal: MXU SIMD-accelerated rendering (might take a long time to finish, if ever)
