There's an easter egg in this game that apparently remained hidden until long after the game had been published due to it being buried deeply in the game. It was first reported by a user named RaoulDuke on neogaf.com: By entering a code on the audio options screen the commentator/announcer voice will be replaced by a less enthusiastic voice who will insult rather than praise the player's performance with lines like "you're inferior". Also, the turbo boost will sound like a girl meowing like a kitten.
The characters Akari Hayami, Nigel Carver, Rob Haywood and Ricky Winterborn are based on characters from 1080° Snowboarding
, although they do not carry the same name.
