I don't get it? If you look at the patches the way the work is you get a disc ID off of an original and then patch your ISO to reflect the disc ID. How could that possibly work? Why wouldn't the ISO have the same disc ID as the original? They are just inside of the IMG files?
The only conclusion I can come to is that DNAS msut log disc ID's and then if one is logged on multiple connections they ban it? But then they risk the off chance that an original can get banned from online play.
Let me know if you guys know anything more about DNAS verification.
