Persona3Port black screen?

I recently dl'ed persona 3 portable for psp the game works great up too the part where you select the difficulty, after that the game starts and some text comes up, after the text finishes the screen just goes black and is forever loading or something?Help please, i heard good things about this game and i want to play it.Edit: ahh I'm running on 5.50 prom-4

You might have:1. A corrupted copy of the game
2. A possible botched patched copyTry finding an unpatched/clean copy, it might work since most of the older games that are unpatched run in Prom-4.

Replying to #2

ahh thanks for the reply, but I can't dl another one, since i don't have enough bandwidth left.Edit: The game works fine when i got someone else save files, but the problem is when starting a new game it just freezes ):

I had this problem too, but couldn't find a solution, the reason why I haven't played it P3P yet :/

Ahhhh, can't get it to work....

What is the file extension of the game? .iso or .cso?

It's an .iso
