Win the gold cup in the 150cc class. Then, reset the Nintendo 64 system. If done correctly, the title screen will change to confirm that mirrored courses are enabled. Enter the 150cc option under GP mode to access the courses. Note: When racing the mirrored Toads' Turnpike, you will be going against the traffic.
On the Royal Raceway course, follow the yellow road to the right of the big jump to reach the castle from Mario 64.
At the title screen, press R to see the best time trial record for Mario Raceway.
Enter time trial mode and complete a course, beating the time indicated below. Then, choose "Retry" to race the course again. The phrase "Now Meet the Course Ghost" will appear. The course ghosts are automatically saved to the cartridge for future replay without beating the course time again.
| Course | Time |
| Mario Raceway | 1'30"00 |
| Luigi Raceway | 1'52"00 |
| Royal Raceway | 2'40"00 |
- Air increase
Line your kart up directly behind another next racer. Wisps of air will appear from the sides of your kart. The small speed increase that your kart will gain should be enough to pass the racer that is being followed.
- Turbo start
At the instant between the dimming of the second light and the flashing of the blue light at the start of the race, press A to accelerate. If done correctly, your kart will rapidly accelerate ahead of the other racers. Note: Accelerating too soon will result in a spin out.
- Turbo boost slide
To slide around a corner, hold R and press the Analog-stick to steer in the direction of the turn, then to the opposite direction. If done correctly, the smoke from your kart will change from white to yellow. Continue to hold R and repeat the steering motion with the Analog-stick to change the smoke from yellow to red. Release R once the smoke becomes red. Now the speed of your kart should increase for a few seconds.
- Banana peel recovery
When a banana peel is run over, immediately hold the brake for one second, then accelerate to avoid skidding or losing a balloon in battle mode.
- Quick restart
After falling off a course, watch as Lukita places your kart back on the track. When your kart is two or three tire widths from the track, press A to immediately resume the race.
- Turbo start
