Wave Race 64

Quick start:
Hold both Gas buttons just before the announcer says, "Go!". Done properly, your speed should increase immediately to maximum power.

Extra points:
Pause the game immediately after a stunt and just before the announcer speaks in stunt mode. When done properly, only the announcer's voice will be heard. A large number of extra points will be awarded for simple stunts. Another way get extra points is to cross the finish time as the clock reaches zero.

Color select:
Highlight a character and hold Up on the Analog-stick when selecting a jet ski to choose between two different color schemes.

Dolphin ride:
Note: This trick will not work on v1.1 of the game. Select stunt mode and ride in Dolphin Park. Go through All the rings and perform the following stunts:

+ Handstand (off throttle, Down and Up)
+ Spin (off throttle, sweep Analog-stick clockwise)
+ Stand (off throttle, sweep Analog-stick counterclockwise) and Somersault (hold Down)
+ Roll left (off ramp, press Right and hold Left)
+ Roll right (off ramp, press Left and hold Right)
+ Flip (off ramp, hold Up and press Down)
+ Dive (off ramp, hold Down and press Up)

A dolphin will squeak as you cross the finish line to confirm correct trick entry. Exit, select championship mode and the warm up option. Hold Down on the Analog-stick when selecting a character. When game play starts, your character
will be riding on a dolphin. It can perform a Flip, Barrel Roll, and Submarine stunts. Note that the dolphin may only be used within this area. This secret is saved with your game, so that the stunts do not have to be repeated.

Gentle waves and ramps:
Press B just before hitting a big wave or ramp to reduce the amount of air time.

Change view:
Press C-Up and C-Down to adjust the zoom. Press C-Left and C-Right to change the camera angle.

Slide:
Press R to slide on the water.

Baby dolphins:
Select championship mode, normal, and warm up. During game play, follow the dolphin around the course three times mirroring each stunt that it performs. The dolphin will jump over the bridge after the Dolphin Park sign to confirm correct trick entry.

Killer whale:
Same as the baby dolphin trick, except the dolphin must be followed for twenty course laps. A killer whale will appear to lead the baby dolphins.

Penguin:
Same as the baby dolphin trick, except the dolphin must be followed for one hundred course laps. The penguin will be wading around the shore.

Reverse mode:
Win the game on expert mode. After the ending sequence, return to championship mode and choose the new reverse mode option to go through the course backwards.

Fast recovery:
Repeatedly tap A after falling off the jet ski to climb back quickly.

Undocumented moves:

Double Flip
This move is done with M. Jetter. Perform a regular flip but tap Up just
before leaving the ramp. This trick is worth over 2000 points.

Helicopter
Turn sharply diagonal at the ramp and hold Down at liftoff. Your racer should
turn sideways and do a flip.

Triple flip
This difficult move can only be done in Glacier Coast with M.Jetter. Get as
much speed as possible when approaching the big ramp. Go up the ramp and tap Up
just before end of ramp, then hold Down. This trick is worth at least 5000 points.
