I just got my first psp yesterday after geting a$75 giftcard in the snell mail. I've read here and there about what firmware upgrade/downgrade to run homebrew. I don't want to brick my psp right out of the box.(I'm not 100% convinced I want to keep it yet till I get something cool to work).So my question is. I have firmware 1.52 I want to run as much homebrew a possible. what firmware do i need to change my psp to?
