if you have empoleon go to route 228 you will see a old man he teaches hydro cannon but your empoleon has to really trust you.
Why do you need a cheat code for Hydro Cannon????????????????????????????? If you have a Blastoise, Swampert, Feraligatr, or Empoleon you just have to bond with it and you can learn the move WITHOUT messing up your game with hacks.
hydro cannon
go to the dessert and take your blastoise/empoleon/feraligatr/swampert with you (they need to love you very much however) and get in one of the houses and talk to the old man
you cant only in Pokemon pearl,diamond and platinum
