Go-Kart Code:
Follow the directions below and you’ll be able to use Go-Karts on any of the
tracks you’ve unlocked so far. You can actually play through the entire game
using Go-Karts! Hold the L and R buttons. Then, push right on the D-pad and
B simultaneously. You will hear a chime if you entered the code correctly. Go
to the main menu, and you will see that you have unlocked the Extra 1 mode.

Secrets to Success:
– Driving the most powerful car is not always the best option for certain tracks.
For example, on most tracks, a car such as the Toyota Vitz will get soundly
beaten by a fully upgraded Honda S2000. However, on city courses and other turn-heavy
areas, it’s best to choose cars with good handling and acceleration. Having
too high a top speed can make your car difficult to control on courses that
require precise turns.
– In championship mode, finish first as often as you can. If you finish second
or third, give the track another shot–you will reap much better rewards for
taking the gold!
– When challenging a friend in vs. mode, choose your car wisely. The player
who enters into vs. mode first gets to choose the track. You won’t want to drive
a Honda NSX on a winding dirt track!

Get Formula Cars (Extra 2):
At the very first screen which comes up in the game (where it says push start)
hold down the L and R buttons and while holding them both down hit right on
the control pad and the B button at the same time. A chime will sound if you
do this corectly. Now press start and at the main menu choose extra 2. Now you
can race with formula cars.

Extra Mode 1:
Go to the screen with “Start” and a picture of the car. Hold R + L, then press
Right + B until a chime is heard. Alternately, select championship mode and win
the beginner, middle, and high speed classes. An “Extra 1” option will now be
unlocked at the main menu. Select it to race in mini-cars.

Extra Mode 2:
Go to the screen with “Start” and a picture of the car. Hold R + L, then press
Left + B until a chime is heard. Alternately, select championship mode and win
all four classes. You must finish in first place in all races. This will unlock
the Formula 1 car and the “Extra 2” option at the main menu.

View Credits:
Go to the screen with “Start” and a picture of the car. Hold R + L, then press
Up + B to view the ending credits.
