Okay so here's the deal.
I'm planning on downgrading my brother's PSP. I can't find a battery anywhere, so can I use his? I heard that you can use it still afterwards as a normal battery as well.
Will it screw his psp up? WILL IT ASPLODE?
(I'd be making the battery with my PSP Slim CFW I guess)
Edit: Also, I don't have a 256mb memory card or anything, so could I just use his 2gb, turn it into the "magic" memory stick then use it as a normal memory card again?
