Why is it that Final Fantasy X files will not read of the game dvd? Even after making an iso with dvd decryptor I can not read them in iso buster or Ultraiso. The iso file size is over 4 gig but the files listed dont even add up to 10Mb. I know that there are other ways to back up this game. However I am not wanting to back it up. Just wanting to understand why If anyone knows why some discs wont show the files please share.
