So I have a few games that wont boot, give me a dirty disk error or unreadable disk. I was just wondering if the reason for this is cause those games weren't properly stealth patched. If anyone could shed some light on this for me I would appreciate it. Thanks and Please don't flame.

if you moved to ixtreme, then they will need to be fully stealth before you can boot them.

check them out with dvdmulleter or whatever it is to see if they are ixtreme compatible

If it is only a few, just redo the backups, to make sure they are fully stealth
