I tried, every region didn't work even "Debug Type I" or "Debug Type II" , It's still showing the same message "This disc cannot be started, the region code is not correct"
Excuse me, I wanna ask, my PSP 1000 series has just instilled custom firmware as 6.60 PRO-C2, so how can I modifiy it to play multi-region UMD's movies? Thank you very much!
