Hi, I am currently using firmware 3.03 OE-C and tried to play a copy of CSO video file which cannot be done. I downloaded UMD Emulator V0.8C and followed the instrucitons: 1) copy UMDEMULATOR & UMDEMULATOR% to PSP/Game folder 2) copy UMDEMULATOR to root of ms 3) copy the CSO video file to ISO folder 4) changed my kernel to 1.5 However, I still get the corrupted picture error message in the PSP game menu. Did I done any thing incorrect or it cannot be done. Appreciate advices. Thanks.
