How to use the BodyForce:
1) Before starting to play the game, put in the game into the console and plug in the bodyforce into the console while turning on the sensors on both the arms and feet so then the radio frequencies would get picked up from the receiver on the mat.
2) Next, while the game is loading up, you can select any option in the game using the directional pad on the mat and enter those options by applying a punch or a kick to trigger the sensors on your hands or feet.
(A separate option that would make your Bodyforce experience easier would be to set some hot keys on the L and R triggers on the PS2, Xbox, or PC. To do this, select the options action in the main menu of any game. Next, then select the controller options and then begin setting up any button actions on the L and R triggers.
For example: for Tekken 5, go to options, controller options, then hold either L1, L2, R1, or R2 and set them with either LK+RK, RK+LP, LP+RP, and etc. LK meaning left kick, RK meaning right kick, LP meaning left punch, and RP meaning right punch.)
3) After setting some hot keys on your directional pad on the mat to make your Bodyforce experience easier yet fun, you would be able to start the game and begin playing any fighting game!
