Hydro Thunder Codes -

All boats and tracks:
Get one of the top five times in any track and enter ?DL as a name. Note: Enter ?PB as a name in the European version of the game.

Fishing boat:
Enable all hidden tracks. Highlight the Thresher at the boat selection screen. Then, hold L + R and press Y(2). Select the Chumdinger to race in a fishing boat.

No timer:
Press X + Y + B + Start at the main menu.

Quick start:
Note: This trick assumes the game is under the default controller setting. Hold L before the race begins. When the number "3" appears release L and hold R. When the number "2" appears, release R and hold L again. When the number "1" appears, release L and hold R. This should result in a start with a four second boost. Adjust your timing to when the numbers begin fading before switching buttons if you do not get the boosted start.

Boosted jump:
Collect boost power-ups, then hold L and press A to jump without a ramp.

Full pause screen:
Pause game play and press X + Y to remove the text from the screen.

Medium difficulty tracks and boats:
Successfully complete all three easy difficulty tracks in first, second, or third place.

Hard difficulty tracks and boats:
Successfully complete all medium difficulty tracks in first or second place.

Bonus tracks and boats:
Successfully complete all medium difficulty tracks in first place to unlock the Nile Adventure bonus track. Successfully complete this track in first place to unlock the next bonus track. A total of four bonus tracks can be unlocked by finishing in first place. All four bonus boats (Fishing Boat, Armed Response, Blowfish, and Tinytanic) will be available after all four bonus tracks are unlocked.

Select two player mode and on the first three tracks medium boats and tracks will appear: Race on the three tracks and hard boats and tracks will appear. Race on all three tracks and the Nile track will appear. Race on the Nile and three other bonus tracks and all boats, including the fishing and tour boats will be unlocked. Keep playing in two player mode to always finish in first place.

Hint: Boost in NY Disaster:
In NY Disaster, when you are racing through the left side of the subway tunnel with the Rescue boat cutting you off and bumping into you, instead of jumping for the nine second red boost in the center to the right, bash into the Rescue boat. Your boost level will remain where it was for the remainder of the race.
