Cheats for Lego Racers (PS1)
Hold X before each track appears. When the countdown starts, tap X along with the countdown, and hold X at the end. If done correctly, your car will start with a turbo boost.
Select "Build" at the main menu. Select "New Racer" at the "Build Driver" screen. Then, enter one of the following names at the "Make License" screen. After entering the last letter of the name, press Down instead of pressing a button. After entering the code, go directly to the "Build Car" screen and create any kind of car. The code will remain active as long as the driver with that name is in your line-up of available racers.
