Okay so with the coming of Crisis Core in a few weeks I think it's time I finally purchase a PSP. Problem is I want customize/mod/hack my psp so it can play ps1 games and watch movies and all that. So do I just randomly go to a gamestop, buy a psp and then configure it or do I have to buy a certain psp? I know this is possible because I've seen videos and also my brother had a hacked psp before. The only thing I remember him telling me is that I need a ver. 1.5 or something and he also told me that the new psp's can't be hacked/modded. So any help would be appreciated. I know I'm probably stupid for posting this up but I am totally new to this and I just want to get my money's worth.
