I am thinking of getting a physical copy of Corpse Party for the PSP, but before I spend the money on it I want to know whether I will be able to play it or not. Does it vary by the game? If so, does anyone here know whether I'll be able to play Corpse Party or not?

The PSP is not region-locked, at least for game discs (I have both Monster Hunter Portable 3 and Monster Hunter Poka Poka Airou, both imported from Japan), but somehow Persona 4 Arena for PS3 had some form of software region locking, even though the PS3 is also region-unlocked. I've never heard of a PSP game with this restriction, so you should be safe.

PSP is region free so yes you can play games from any region on it. I have PSP and a few Japanese games and PAL games I play on it. I'm in the US

Ka-pi96 said: Yeah, PSP is awesome like that. I've imported some games as well and they've worked fine

That's good. I bought Coprse Party, and it would suck paying as much as I did just for it to collect dust not being able to be played.
