Hi, I'm looking to purchase a PSP for homebrew purposes, but I know absolutely nothing about the PSP or its homebrew, so I've got a couple questions. I want to make sure that I purchase the right item; Can homebrew work on any model of PSP? Do I need certain versions of the PSP firmware? Assuming I do need a certain firmware, are there ways to downgrade from higher firmware? I know that certain PSP models (2000 or higher?) can output to a TV; Can these models be hacked? Can a PSP be bricked/unbricked and is it easy/hard to do so? Can a PSP use SD, Pro Duo, or both? Can I use any size SD/ Pro Duo card? Is there anything I should watch out for when buying a PSP? Is there anything I should know that's crucial to owning/buying a PSP? Sorry If I asked a lot of questions, but I want to make sure I don't screw anything up.
