Wave Race: Blue Storm

Highlight a racer and press Z at the character selection screen.

Towards the end of the track you will enter a twisty river. Run into the brick wall with your Jet Ski and it will break, revealing a path with an ancient temple.

Once you have the password option simply enter "463YWNX3" as a password to unlock this track in "normal" under stunt mode.

Enter "J784WMHF" as a password.

In free roam mode, aim for the island in the background when you first start. Use your turbo before passing the "out of bounds" area. If done correctly, you will see a second area. When you get to that area use your turbo again. This new island has monsterous waves that you can do various tricks.

After passing a buoy or two after the small ice arch and before the ramp, at around 2 o'clock you will se a discoloration in the mountain side. Run into that discoloration and it will open up an underground penguin lair. You can cruise around the shining cave before hitting the icy waters!

While playing hold X+B+Start at the same time.

Enter the option menu and then the "Audio Settings". Press Z until the waveform in the bottom changes to some kind of vertical rising fog. Now, press Up, Up, Down, Down, Left, Right, Left, Right, A, X, Z. If done right, a sound will be heard. Now, start the game and pick Ryota Hayami. From now on, the announcer will insult you all the time.
