I've recently purchased a used copy of Soul Calibur 2 and I wanted to play it off my XBox hard drive. I've got the Aladdin Advance mod chip installed and flashed with EvoxM7 bios (by the way, what is the "ef" version of this bios). I put the game in the xbox dvd drive and connected via ftp from my pc to the xbox and copied all the off the files off the DVD to my pc hard drive, then copied them back over to the xbox to a new folder on the E: drive called Soul Calibur. I can launch the game from EvoX just fine and it starts but then I get a "Dirty or damaged disc" error. How is this possible since I'm playing off the hard drive. I've also had this same problem with playing DVD-rw backups...any ideas...thank very much.
