"Play as Tekken
 Force fighters"
                 Yes! You can play as Owl/Hawk etc! Here's how to get this code to
                 work: Select any character and start the first fight normally.
                 Anytime during that fight, press L1,L2,R1 and R2 simultaneously.
                 On the next opponent, your character should change. Hawk, Owl
                 and Falcon are just different costumes (like Panda and Kuma.)
                 Picture here.

 "No darkness"
                 When you play True Ogre, the background doesn't go dark. Funny
                 thing is, the game doesn't slow down noticeably.

 "Kougeki Koutetsu

                 Here are the girls' moves. Remember to turn on "Kougeki Koutetsu
                 Enable" when you use these codes. You don't need to key in every
                 single one of these "Kougeki Koutetsu Group X"s if you think you'll
                 strangle your fingers on the slow Gameshark menu. Just select the
                 sets of moves you like best.
