Hey... i'm new to this homebrew gaming thing and i hav upgraded my psp from 3.52 m33-4 to 3.71 m33. But... it has a problem wif both of the versions that i hav used. I had put 4 games into my psp and only 2 showed up which was 300 March To Glory.cso and Def Jam The Takeover.cso. When i downloaded this games it was already in cso file, but when i downloaded Ghost Recon Advanced Warfighter 2.iso and Prince Of Persia Rival Swords.iso, it won't show because it is an ISO file. How can i fix this? I also hav already tried converting my ISO files into CSO and it is still not working. PLZ HELP!
