I think what he is trying to get at is a modchip which prevents backups from working, although still allows booting of import titles etc.
Thus making the whole process of creating a backup irrelevent.
It simply amazes me how us gamers get classed as criminals etc due to us to backup our games. Yet everysingle person I know has either taped something off radio or a film off tv...........WHILST NOT OWNING THE COPYRIGHT FOR THEM! I was amazed when finding out that the above two were actually naughty too...although they are so heavily promoted with the addition of videoplus numbers etc.
Hmmm,
I'm going back to sleep.
