When I insert my battery first only the power light comes on, but when I insert the magic memory stick the other lights turn on, so I'm not quite sure whats up. :confused1:
Oh yes and the memory stick I used was a pro duo sandisk (512mb)
I should also say that I also used a fat battery in a slim, but I was told that it would still work.
Yeah, I forgot to mention that you'll need to boot your PSP without the battery and have the AC adapter inserted. Then follow the magic memory stick portion of the guide again.
