Hit the last hut before the finish line (along the small path to the left). Run over the Daisy Box to unlock the Battle Time Limits cheat.
Before the Jurassic Park is a shortcut to the right. Follow the shortcut and slow down while you are approaching the big hut so while you are in the air from the jump you can put on your handbrakes. If done correctly, you can stay on the wooden platform that the hut is on. Break open the hut and on the far right of the platform is a Daisy Box.
In the town, the first shortcut on the right has two small jumps. On the second jump, hold Analog-Stick Left because there is an opening there. If you land on top of it, drop your car on the roof of the building, where another Daisy Box is located.
Hint: Metro Madness Daisy Box:
In Metro Madness, take the shortcut to the left of the barricade after the first tunnel. Break through the glass doors in the center of the first building on the left. After reaching the railroad tracks, turn around and go backwards on the tracks. Your car will eventually hit a Daisy Box.
Far through the race are few tunnels. After coming out of the one that curves hard three times, the road is straight. After a short distance, you can see two nitro blasts that close to each other on a hill and one that is not. Approach the one on the hill, but do not hit it. Instead, turn left into a bridge between two shortcuts. Inside, there is a Daisy Box.
Hint: Mount Mayhem Daisy Boxes:
Locate the ski fest in the town. There is a hole in the short little wall where you can go through into a jump. Jump in at such an angle to get on a pretty flat piece of land that is way left of where the hole is. You probably will hit the wall, but if you go backwards far enough you will find a Daisy Box.
After a big jump inside some type of a crystal cave, there is a large orange bridge that slopes down and goes back up. After the bridge is a tunnel. Look behind you at the end of the tunnel to see a Daisy Box. Turn around and run over it.
Hint: Sunset Sands Daisy Boxes:
At the beginning of the race, go right and drive through a space in between two tall rocks. Continue up the hill of sand it turns flat to find a Daisy Box.
When you turn on the game, it will display a shortcut for each course. Note the Sunset Sands shortcut that is shown has a Daisy Box. In the shortcut, the first Daisy Box is in a tight space which turns harshly and then has a jump onto a straight and flat surface followed by another jump. Once you land use the handbrake and turn right, facing the wall. Drive up to it and turn right again. Drive forward until you reach the daisy box.
Hint: Car spins:
Select a car with bad steering and high speed/acceleration. Go to a track with jumps, such as Inferno Isle. Immediately before the jump, slam on the hand brake (not the regular brake) at the same time you turn left or right. Note: A few attempts may be needed.
Glitch: No horn:
Crash into any object, then hold C-Right immediately after hitting it. When game play resumes, the horn sound will be disabled, but will actually still be considered on by the game.
