Darkholme: Figured I'd check this thread out as you referred me from the other one. This is an interesting topic... I know next to nothing about the PSP version, though, so I could probably only offer logical/process insight, little else... (Unless randomly writing ASM helps things, but somehow I doubt it )
I read a theory somewhere that the slowdown could have something to do with the PSP's vertical sync being slower... but if the PSX version runs fine on the PSP, then that wouldn't explain it.
One question, and maybe this has already been addressed, but what would happen if you took the effect files from the PSX ISO and put them into the PSP version? The idea being that the effect files have something to do with the animations, so maybe they could also affect the speed...
