You may be confused. You can not change which commands your 4 IR buttons perform during a match. I.e., if IR button 1 is "move forward", you cannot use another button to change your command set so that the IR button later means "move backward". You also cannot toggle state like this "Press once, go forward. Press again, stop. Press again, go backwards. Press again, stop."

You MAY change what your four buttons do in between matches, assuming you have your index cards filled out with the 4 (four) (IV) commands that the buttons will perform.

Note this part of the GDC response:

>>If there was a one-to-one mapping between the transmitted functions/register settings and the resulting
>>commands/actions, then it would satisfy the signaling requirements.

The rules, as spelled out by the GDC, are extremely clear. One button, one command. It always does the same thing during that particular match.
