I have a question for yall, I bought this used shortly after it came out in fact the same week. I thought it was a bit odd. I haven't installed the game myself and everything was running fine about 30 hours into the game I noticed it takes a long time to load certain things, fights, cut scenes even the game itself. When I turn the PSP upside down it loads instantly every time. Do you think I have a bad disc? or is this simply just my imagination?
