It's important that you do what the dolphin does, so if it does a
     barrel roll as it clear the jumps, then do barrel rolls; if it does flips,
     then do flips, etc. The dolphin seems to randomly make a choice as
     to which trick (if any) it performs each time you turn on the
     machine, so if you aren't good at the tricks, keep restarting machine
     until he's just clearing the jumps.

     To see the killer whale, repeat this trick 30 times without a mistake.
     Good luck!

Big Dolphin
     To view the big dolphin, you must go to Championship, Normal,
     then Warm Up. If you do this 20 times consecutively you will see a
     larger dolphin in Dolphin Park.

Change Colors
     While selecting your jetski, highlight any character and hold Up on
     the analog stick. Continue to hold until your character and jetski
     change color.

Dive Under Water
     As you start up ramp, press and hold Up. As soon as you clear the
     ramp, press and hold Down to dive under water.

     Hint: This works best with wild waves. It just slows you down with
     calm waves.

Dolphin Ride
     Select Stunt Mode mode and enter Dolphin Park. Next go
     through all the rings and perform the following tricks:

          Handstand
          Backwards spin
          Stand with backflip
          Single backflip off ramp
          Dive off ramp
          Barrel roll off ramp in both directions
     If you did the trick correctly a dolphin will squeak when you cross
     the finish line. To ride your dolphin, select Dolphin Park in a
     Championship Race and hold Down while selecting your racer.

Double Flip
     First get some speed with the jet ski. When you are on the ramp
     tap Up one inch from the top of the ramp and hold Down to do
     your flip. Instead of making the character do one complete flip hold
     the Down button longer so he does another turn. If you do it
     correctly he will land perfectly and ride on.

     Hint: J.Meter is the best racer to do this with; especially on the
     small ramps.

Double Side Flip
     This stunt can earn you over 2000 points if done properly. Head
     straight at a ramp and gain as much speed as possible. Then about
     an inch from the top of the ramp push the joystick in the up/diagonal
     position and then pull down and hold. If your timing was right you'll
     do a side flip, then a back flip and land perfectly.

     Note: J. Meter is the best one to do this with.

Easy Points
     Press Start as soon as you complete a stunt. If done correctly all
     sounds should stop except for the announcer. You want to pause
     the game as soon as the announcer starts talking after you do a
     stunt. If done correctly, you can get up to 30,000 points on a level!

     Addendum: For even more points, cross the finish line at 0 time.
     This will push your score even higher!

Helicopter Trick
     Get up as much speed as possible and head for a ramp. As you
     reach the peak of the ramp, press the control stick Down and Left
     or Down and Right.

Reverse Courses
     If you win the gold cup on Expert, you get a Reverse option. Unlike
     Mario Kart 64 where the tracks are only "mirrored", in WaveRace
     64 you can actually run the courses in their opposite direction.

Ride Backwards
     To ride backwards, rotate the joystick clockwise and quickly press
     and hold Down.

Start With Max Power
     At the start of the race, press the Accelerate button immediately
     before the third beep.

Turbo Charge
     For a faster jetski, hold the gas button immediately before the
     announcer says "Go!" The closer you are to the announcement, the
     faster your jetski will go.
