Lair is fully playable (without L2/R2) on your PSP when you use the remote connect feature, it will not work the first time but remote connect again and there it is fully playable with your PS3 save, the only catch is you must have beaten the traing level becouse it forces you to use the L2/R2 buttons(not on PSP) then save after first mission and remote connect and play to your hearts content!!!!! I found this from 1up.com
