CheatCodes.com has all the official Hydro Thunder Dreamcast cheats to unlock everything. If you know of any that we don't have, please let us know.
All published and official codes as of Saturday May 18, 2013 for Hydro Thunder are shown below. We also have this game on PlayStation, Nintendo64, Dreamcast, and sometimes tricks from other game systems will also work on Dreamcast.
At the beginning of any race, hold L before the countdown begins. When you see the number "3" on the screen release L and hold R. When "2" appears release R and hold L. When "1" appears release L and hold R again. You'll get a four second boost and a fast start when the race begins.
Put the disc in the system, open the lid, and turn it on. Go to the icon with the music note and hit "A." Now close the lid and hit "Play." After a cheesy voice says, "This disc is for use only with Sega Dreamcast," another track starts playing. Subsequent tracks will have the rest of the music.
Pause the game and press X + Y.
Note: This trick assumes the game is under the default controller setting. Hold L during the pre-race countdown. Release L and hold R when the countdown reaches "3". Release R and hold L when the countdown reaches "2". Release L and hold R when the countdown reaches "1". If done correctly, your boat will get a faster start and a four-second boost.
