checked-part
 =>Special Cup: After you earn the gold trophy in all four cups (Mushroom,
   Flower, Lightning, and Star) in a single class (50/100/150), the Special Cup
   will be selectable on the "Choose A Cup" screen for that class.
 =>Extra Tracks: After you earn the gold trophy in all five cups (the standard
   plus the Special Cup) of a racing class, you can enable additional racing
   tracks for each cup. All you need to do is gather at least 100 coins in a
   Mario GP race to enable four additional tracks for that individual cup. To
   race on these tracks, just return to the same cup on the same class (50-150)
   and press [L] or [R] to switch to the Extra Tracks. They will be visible on
   the screen.
     Please note that if you earn the Extra Tracks for the 50cc Mushroom Cup,
   they are open ONLY for that cup. To race them in 100cc Mushroom Cup, you
   will need to earn gold trophies in all 100cc Cups and gather at least 100
   coins in a race through the 100cc Mushroom Cup.
 =>Horns: During a race, pressing [SELECT] honks your character's horn.
 =>Selection Screen Tricks: When you are selecting your player, and they are
   rotating on the selection screen, you can press [SELECT] to honk your horn,
   and [L] or [R] to hop and fire shells.
 =>Change Title Screen: Once you get the gold in all 50, 100, and 150 modes,
   the background color of the title screen changes from blue to red.
 =>Turbo Start: Hold down A just before the green light appears. If done
   correctly, you will zoom out in front. If not, your character will spin in
   circles when the race starts.
 =>Time Trial Extra Tracks: To enable the Extra Tracks in Time Trial Mode,
   simply enable them in 150cc.
