Halfpipe level
Complete the endurance (all levels) with any normal character. The halfpipes are being carried by trucks.

Unlocking levels
Master all of the points for each level to unlock the next level. As you unlock each level you also get the photo shoots at each area. As you get photo shoots, you must gain anywhere from 1000 points and up for each photo.

Unlocking hidden characters
Place in the Huntington Tournament and unlock the Photo shoot. You will unlock a different character with each skater that earns the photo. You have to get 8000 points in one move. You can angle towards the fun box that has a quarter pipe with two rails on either side -- you start out facing it. You have to launch off the quarter pipe with a Nollie/Boneless then do a big trick like a Flip or a Christ Air. Land on the rail, grind, then jump off and Kickflip. It is tough to pull off, but is worth over 8000 points.

Willy Santos unlocks "Skator".
Cara-Beth Burnside unlocks "Hang Man".
Ed Templeton unlocks "Demon".
Daewon Song unlocks "Rex".
John Cardiel unlocks "Stanley"
Pigpen unlocks "Daave Carnie"
A female custom skater unlocks "Stinger"
A male custom skater unlocks "Golgotha"

the skaters
Unlock all the rooms in one of the wings. Then, collect all four coins for that wing. There is one in each room.

To open the Dream House, you must first unlock all of the levels. Then, play all of them at least once. You have to get everything in a level to get a key. The key will open a room to the Dream House.

Rollerblades in pool
When you get a key for your dream house (east wing), open the aqua room and use the skater's eye at the pool with the shark in it. Instead of fish, there two pairs of rollerblades will be there. Note: You cannot use the rollerblades in the pool -- you can only look at them.

Atlanta: Hidden area
Go to the second platform and jump to the roof. Go over there to find a new area. Once there, you can grind to another new area with a bowl and some rails.

Avoid modified PlayStation error
This trick is useful when playing the game on a PlayStation that has a mod chip. Immediately after you start skating, open the PlayStation's CD lid. When the disc stops spinning, close the lid. This will allow the game to continue, without the modified PlayStation error message. You must do this every time you start to skate.
