When you put in sellout or that other one aprils man they dont work AM I RIGHT? Well these cheats are for real :) I JUST tried them!!!

unscrewed --> unlock THPS1 tony hawk and Natas Kaupas.(In the secret char. menu)
urown3d --> Unlock all levels
sikflick --> (all movies pro bails 1+2 ETC. NOTE You will not get the cheat movie
likepaulie --> always special
straightedge --> perfect rail and lip balance

If those dont work youre spelling is wrong if it does not work the second time do it again if you think my spelling is wrong after you try them then contact me at thundadrake@hotmail.com
