Start the game, then go to "Campus Challenge". Select the pennant(s) you wish to use during the game, then exit back. Go into "Settings", then "Control Settings". The other player(s) can now choose to be on your team or the opposing team. An error message stating that Campus Challenge is now disabled and nothing can be enabled will appear. After this, there will be a message stating that it will take effect after the following play. Once the next play is finished, the players will be recognized and the pennants will still be in effect, even though the game said they will not be.
