| 8 | Stop/Restart Timer (L3=Stop Timer, R3=Restart Timer) This will allow you to stop the Timer and restart it. The side effect of this code though is that it disables the CPU Racers AI. When activating the code in Drag Races, press L3 and wait for the CPU Racers cars to stop moving. After they have stopped moving, press R3. You can then continue the race without worrying about them. When using it in Circuit and Quick Races, just press L3 and continue on with the race. Then when you reach the finish line, press R3. Don't use this code in Sprint Races. You and the CPU Racers cars will just slow down and stop. |
