This game is pretty difficult, but, it doesn't have to be. You can unlock all of the
tracks and tripods by entering this code at the Main Menu. We had to attempt this code a
couple of times to get it to work, so don't become discouraged if it doesn't work the
first time. From the Main Menu, simply highlight the Vehicle Select options (do not enter
the vehicle selection option). Press and hold X + Y and enter the following code: UP,
LEFT, DOWN, RIGHT (TWICE), UP, DOWN, RIGHT. Now, you may enter the Vehicle Slection
option and choose the best vehicles the game has to offer.
