Top Skater

Play as Alex:
Select a course, then press (on the machine) Left three times, Right three times, Left thirteen times at the character selection screen.

Play as P-Nut:
Hold Start at the course selection screen. Wait for the character selection screen to appear, then press (on the machine) Right six times, Left six times, Right three times, Left three times, Right four times, and release Start.

Big head mode:
At the course selection screen, press Left nine times, Right nine times, Left four times, Right four times, Left five times, then step on the Front of the Skateboard and press [Left + Right] three times. The sound of laughter will confirm correct code entry.

Bonus track:
Select advanced level and any character. Repeatedly step on the Front of the Skateboard before the board unlocks. When the game starts, intentionally miss the first jump and crash into the fence on the left side of the church to reach a hidden track.

Select stance:
Highlight a character at the selection screen and press Left + Right to toggle normal and goofy footing. Note: This has no affect on P-Nut.

Hint: More points:
More points can be achieved by using the nollie (short jump) in the half pipes instead of using the big jump, which puts you farther down the pipe without getting more jumps in.
