So I just got a PSP. I've known about the hacking scene for a long time, but I just haven't ever had one. I have a friend who did back in 2005/2006 and he got it to work fine. I started trying, but it turns out I need two things since the firmware on mine is currently 3.90: a Pandora Battery and a "magic memory stick." Now, is the pandora battery a one-time use thing? Once I get it to work, will I have any use for it in the future? Do I need to keep it locked away for backup purposes or should I find someone to pawn it off on? And second question, about this "magic memory stick." I have a Memory Stick Pro Duo already (thank my parents for getting me a Sony camera a few years ago). Can I just format it to get rid of the information and use it for this Pandora thing, then reformat it again and be useable? Or should I get a new memory card just big enough to start unlocking this large-screened device for it will then be ruined? Sorry if I know this is noob related, I just can't find this kind of topic elsewhere. If you know of one, just redirect me and thread = deleted. Or at least closed.
