Alright, I've read through a dozen guides, but am completely lost. Here's my situation: 1. Slim PSP w/ 3.71 Sony FW 2. PSP Fat Battery that I hard moded --I don't know if I did it correctly though. I cannot power up the PSP when I put the battery in, however, if I connect the PSP to AC power and then remove AC power the battery seems to power the PSP (green light stays on). Yet I cannot power down without taking out the battery. 3. 4GB Sandisk Ultra II MS 4. a "drag and drop" Magic Memory Stick file set --I have a mac and cannot make the MMS on my own So my issue is that whenever I power up the PSP (through AC power) it does nothing. The orange power light comes on (it's green when I disconnect AC), but nothing ever happens. Is this a problem with the battery or the MS or something else? Thanks!
