Before you start playing in arcade mode, a screen will appear saying
what the rules are and how long the quarters are and so on. So, press
the back left trigger and the screen will change to a screen where it
says how tough the referees are. Below and above that are what the
penalties are. You can toggle them to turn on or off and you can turn
off the really stupid rules like the three second defensive rule. (don't
even know what that means?) Well... Play away!
