Half minute hero, p3p, and peace walker are working for me. GoW:CoO runs, but there's some slowdown at certain parts. I think it's because it's a CSO. Going to try to find an ISO of it.
Running 5.50 prometheus. No plugins. PSP 2001 daxter edition.
EDIT: found an iso of gowcoo, and it's still pretty laggy. I refuse to play god of war like this. I'll wait until Ghost of Sparta and pray that the dump will be good.
Final Fantasy VII Crisis Core also has some pretty nasty slowdown during cutscenes. These are CLEAN roms (or so I think.)
EDIT EDIT: I'm reading now that converting the crisis core iso into a cso should make the slowdown disappear. Should be the opposite, really... will compress and post back if it works.
EDIT EDIT EDIT: Amazingly, compressing a crisis core ISO into a CSO makes it run flawlessly. Menu, opening cutscenes, battles all work. No crashes so far. In fact, I have yet to experience a crash on ANY of my games.Only slowdown. I can't figure out how to stop the gowcoo slowdown and the Daxter slowdown. At least I fixed crisis core
EDIT EDIT EDIT EDIT: Forgot to mention; Soul Calibur Broken Destiny and Monster Hunter Freedom Unite work flawlessly too.
