Hey, my God of War: Chains of Olympus PSP-2001 is having some problems. I got it from a friend, and he said it wasn't playing UMDs. I came to find that UMDs will not even spin, so the disk drive is obviously having problems. The PSP is modded with system software 5.50 GEN-D3. It has Project 7 (I have no idea what that is). If anyone could help me with some advice or methods to fix it, I'd really appreciate it. For now, I'm just gonna play the many emulators he has on it.
