GameShark Setup
Insert the GameShark disc and load the "Select a Game" menu. Scroll down until you reach "WWE Smackdown! vs. Raw 2010" and press "X." On the cheat list, activate the "Master Code" and then press "O" to reach the new code entry screen. Here you will type the title of the code and enter the digits to activate it.
Height Hacks
Change the height of WWE Superstars. For example, you can make the Great Khali as small as Hornswoggle, or increase the size of Shawn Michaels to match with the Undertaker. Choose the superstars you want to change the height to, use their specific height modifier code and then enter the height adjustment code. For example, Chris Jericho's height code is "104D78FC 000000." Add "1198" at the end of that code to set his height to 7 feet.
Ability Hacks
Use ability hacks to make the Rock a hardcore legend or the Big Show a cruiserweight. Use the initial character code and then add the ability code to perform the hack. For example, the Rock's code is "004D75B4 000000" for his main ability. Add "0D" to give him the hardcore resurrection ability. Other abilities you can modify include "Ladder Match," "Dirty Pin" and "Kip-Up."
Joker Commands
Joker commands turn your controller into an instant command that can set new champions, allow wrestlers to fly through the air or switch wrestlers in the beginning of the match. Set the first player joker command with the code "Ennndddd 01C63802." Replace the "dddd" with the input button you want to set. For example "FAFF" sets the joker command to "L1" and "L2." Once entered, select the GameShark cheat you want to associate the joker command with.
