Eight Tracks:
Go to Arcade Mode and enter the "Bonus Items" option. You should see the letters A, B, and C above each of the levels given. As you do the following, they will be covered with a blue, yellow, or red dot. To fill in the four big question marks, go back to the main Arcade Mode screen. Then, go to "Single Race", choose any difficulty level, and place first in each of the four original levels with an A class car e.g., Mitsubishi GTO, a B class car e.g., Mitsubishi Eclipse, and a C class car (ex: Honda Civic 3-Door). After you have done this, go back to the "Bonus Items" menu and the four big question marks should be filled in with these levels: Autumn Ring, Deep Forest, SS R5, and Grand Valley Speedway. That totals eight tracks.

To get the GT hi-fi mode:
Finish the GT world cup then the GT hi-fi mode will be appear in the special event.

In arcade mode, winning first place, on any of the original four tracks, in all three classes of vehicles (a, b, c} will open a new track ( a total of four). If you come in first on all eight tracks, in all classes of vehicles, on the EASY difficulty setting, four new car manufacters will be available for you to choose from (Toyota, Subaru, Dodge, including a concept car, and TVR). If you win first on all eight tracks, in all classes of vehicles, on the NORMAL difficulty setting, a cheesy movie and the game credits will be available.


Break the sound barrier in GT:
Select a 4WD car. Start and get some speed. Hit a wall at 90 degree. Hold the throttle open. Now your car is stopped, wheels spinning and smoking. Slightly steer to whichever you want to go. Suddenly your car is accelerated. Try to keep your car sticking to the wall so that the acceleration continue.

Licenses:
First 2 parts of getting license B - you must come to a complete stop in the checked area at the end of the track within the time limit (36 then 27 - i think).

In all the sessions you must get under the time on the description screen, but on the first 2 you've also got to brake and stop on the checkered bit after the finish line. Your time doesn't count until you've completely stopped.
