Wave Race: Blue Storm
Wave Race: Blue Storm
Attachment
At the game's Audio Settings, if you change the waveform display so that it appears similar to vertically rising fog, then input Up, Up, Down, Down, Left, Right, Left, Right on the D-Pad, and press A, X, Z, and then choose to play as Ryota Hayami for any race, the narrator's voice will be changed to an unfriendly voice, and the turbo sound effect with a little girl meowing. This Easter egg went undiscovered for 9 years.
