How:
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 (ex: Mitsubishi GTO), a B class car (ex: 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 makes 8 tracks!
