Dissidia 012: Duodecim Final Fantasy - ULUS10566

[hyakki]

Prologus has the same problem where it sticks at the loading screen.
you don't get any benifits from beating / playing it except being able to import your save data..

and you get the aerith assist character when you purchase prologus, though im not sure if it will work in jpcsp dlcs are encrypted and need license files ...etc
