So been pulling my hair out the last couple of days over this and don't understand why. I am running Rogero 4.46 with COBRA 7 integrated. Running latest MMcM Copy game to PS3ISO folder, launch MM and I see game, but launching gives me the "This is not a valid PS3ISO file" However, if I format the drive as FAT32 and put the game on it, it loads perfectly fine! Something about NTFS it didn't like. I was under the impression that you could mount NTFS fine with the hybrid firmware. Any thoughts?
