Backyard Skateboarding Cheat Codes for PC

In-Game Cheats
To enter these cheats your character needs to pull off a 100+ trick combo succesfully. (The best way to do this is to go to the Boardwalk and grind a table near the Hot Dog Stand, then press Space and B alternately and rapidly.)
Then, at the start of a level, during the flyby (Sunny and Eric will be talking) type in any of these cheats to get the effect. (Does not need to be capitalized)
You can only have ONE cheat activated at a time.

Code - Effect:
NOFAIR - All Cheats
