So I just saw this and was a little confused. This is booting simply because there is no media check encoded into it? Does that imply that everytime we use the PI tool to make a backup of a game that there is a media check that is backed up as well? It seems that the media check could just be hexed out of the backup. I know it is more complicated than this as if it were this simple, modchips and all would not be needed. It just seems odd to me that the 360 will play any burnt disc regardless of media check. I thought it had to see something else hardcoded on the disc as far as protection is concerned. Am I confusing here? I am just trying to figure this out. Can anyone explain this better?
