So in 2008, I bought an older PSP off of a friend. It has built in 16 bit emulators, and it's on one of those handles to get a better grip. Actually, that's the battery for the thing.
None of those details have caused a problem… until I got caught in the rain with it in 2009. It was weird for a few days, holding a green light but not turning on. I charged it and let it run out a few times until it was back.
No problem from that point until last week. It's doing the same thing and my method isn't working. I really wouldn't be sure it's dead, but that's mainly because I won't and really can't replace this thing. Advice?
