I was talkin about the DVD drive on a PS2 but its the same for PS3, any method that involves swapping disks is very harmful to the laser...but swap magic isnt for PS3's cuz they dont have a fliptop, in order for u to even use swap magic on a PS3 u would have to open the PS3 and void ur warrenty (see thread below)..best way to play PS2 backups is on a chipped slim PS2....I also have swap magic and its garbage...
