Launch the game you want to bind controls for, enter the config menu, and select controls for this game. Then for the buttons you want to bind to the r trigger, first bind the button you want to assign to it normally, then bind it again to the r trigger. Do the same for the other button. That may not be clear. I'll try again with an example. So for example, you're playing Final Fight and want buttons 1 and 2 to be bound to X and A for punch and jump. But you also want Y to be bound to both 1 & 2 so you can do a special with a single press. You'd bind button 1 to X, and then bind it again to Y. So that it says Button 1 = X or Y. Then you'd bind button 2 to both A and Y. So that it says Button 2 = A or Y. That way when you press X you'll punch, when you press A you'll jump, and when you press Y you'll do a special as the game will think you just pressed X & A together. Even though you didn't. Hoorah.
