On the screen where you choose the Funfest mission you can normally do one of three difficulty levels for any given mission. This code will unlock a hidden, vastly more difficult tier for every mission.
When used, all available Funfest missions will be set to this highest level. Leaving the mission screen resets them to their normal levels, and the code must be re-entered each time.
