Choose practice mode and select a fast car. Jump over the fence in the De Sluis track and drive around to find three skate ramps. Search again and you will find two brown half-pipes. One of them has a open door behind to an arcade. Stand in the corner, drive in front and stop. A game will appear. When you get a game over, you can quit by pressing REVERSE.
