We can rip .iso's (most of us anyways) so no and there is no public method to use it. Im still kinda sad the game isn't going to be available on the PS store
you can rip ps3 games to .iso but you need a blu ray dvd burner drive which costs £££ and the knowledge of how to actually rehash the .iso etc...!
ive only ever witnessed 1 person with an actual working version and it cost him £400 to do it but technically in the long run it saves himn £££'s on games etc.. so pays for himself its meant to be very hard to do tho i know he broke 2 ps3's trying to achieve it.
