wonderamazement SG Mine's homebrew 3.71 M33-2, works fine with .cso files but not .iso files. They do not seem to appear in the xmb under the "Game-Memory" directory...
FrozernFire SG iso files should also work. make sure there’s no ”.” (full stop/period) in the name of the file except before the “iso” extension
FrozernFire SG rename the file to a simple filename eg. "abcde.iso". if it does not work, it is likely that the iso file is corrupt or something. try to open the file using umdgen v4.00. it should be able to tell whether the iso is a valid psp umd iso file
wonderamazement SG Aiya, solved it... Thx guys, i just went to my frequent PSP shop to get a new one la, this one is corrupted... Then i realised, Midnight Club 3 not really nice to play.
