I just bought a 2nd hand PSP and it cam with Spiderman 2 UMD. I tried it in my PSP and it did not load up. I tried the transporter and that worked fine. I am running 3.90 M33-3 firmware.
Any ideas on what the problem might be or is the UMD just broken?
It sounds like a problem with the UMD. It *could* be a bug with the custom firmware but it's unlikely. You'd have to test on a PSP running official firmware to be sure.
