Im new to psp hacking and as my brother is buying an old psp soon i want to help him hack it so it will play isos and homebrew. i have a couple of n00bish questions first though. Which custom firmware is best? How can i hack a psp 1000 and will i need to buy anything like a new special battery? (ive searched aroun for the answer to this and have found nothing that doesn't involve buying something) What size memory stick do you recommend and where can i find it cheapest? if anyone can answer any of these questions it will be much a appreciated.
