A while back I posted a piece on modding a PSP. I know it wasn't the standard route most take but it worked for me. Then about a year or so later that same PSP had issues, it wasn't from the modding. It was just the Analog-stick needed a replacement, even though the repair looks fairly easy. I will fully admit I hadn't fixed it yet. In fact, I bought a 2nd PSP 1000 with plans to mod that one instead.
But this time I went the normal route using the one site everyone recommends Wololo.net and followed the instructions. I upgraded the Firmware to 6.60 and then installed the CFW everything works. Even Cave Story, which I previously forgot I had downloaded...now if I can figure out how to get past the 1st room.
