Edit Wrestler's Favorite Moves
You can't edit a regular wrestler's moves, BUT you can edit their Favorite Moves. Ok, first off Favorite Moves are the moves that the wrestler will use most often when being controlled by the CPU.
Now to edit these moves just go into "Smackdown Mall/Superstar Options/Edit a Superstar" and then select the wrestler that you would like to edit. You can select any of his current moves and make it one of his favorites, or make a favorite move just normal. When viewing the moves, the favorites are marked with an F in a pink circle, and if their's any left over the total is displayed on the bottom right hand corner of the screen.
To change these simply view the move that you want to activate or deactivate as a Favorite and hit your Left C Button. Then save the changes and their you go! One of the first things I did with this was to select Kurt Angle's "Reverse Achilles Lock" as one of his Favorites.
