How these codes work is not by the controller port you're plugged
into, but by the position you're in on the race. For example, if
four people are playing, then position 1 is player 1, position 2
is player 2, and so on. But if only three people are playing, and
no one is plugged into controller port 1, then position 1 is
player 2, position 2 is player 3, and position 3 is player 4.
If there are only two people playing, and they're plugged into
controller ports 3 and 4, then position 1 is player 3, and
position 2 is player 4. Also note that these codes will affect
computer players, which is why they are seperate codes rather than
combined into one code.
