Just picked up the PC version of Corpse Party.
Long story short: The PSP Version is better.
-Different Tilesets, they are less detailed and more colorful. It feels like they were reused from a pokemon game.
-95% of the voices are gone (different actors too)
-No CG Pictures/Avatars/Item Icons, the lack of cg pictures really makes certain events less emotional.
-Sound is not Binaural
It was advertised as being a repolished release of the PC version of blood covered. It's not that great.
