okay so i got the ps3 and i heard you can play ps2 games on the 60 gig version so thats what i bought. i only had enough money for a ps2 game so i got kingdom hearts to relive my childhood. i was so mad when it said it didnt work so i searched it up and says there is something called backwards compatibility. can someone explain how it works to me? I couldnt find it online so far. so any links sasying a tutorial or something i can download to ps3 to make it work would be good.
