just to reiturate, as some might get confused, its not illegal to use iso's made FROM legitemate games you own, its illegal to download said isos from another source who does own the game. for instance, i run my game off isos, but i made these iso's from a legitemate copy of the game i bought from a local store years ago, and i run the iso's rather than the disks because my disks are old and getting beat up, and i would rather preserve them.
so iso's from your own game you already own
allowed
iso's from a source or torrent when you yourself didn't make them?
n
not allowed
