By the way yes you can get any Pokemon by using cheats on Pokemon diamond and pearl. Called Pokemon Modifier you can find the code on YouTube but you need an action replay buy them from any game shop.
I really don't know, but you shouldn't use cheats on any Pokemon game; your game will be Ruined.
you have to do any Nintendo event where you get the Pokemon, and trade and catch for the rest.
For Using Cheats ...You will Need Action Replay which Is Available In any Game Stores...Just Put It In The Game Slot And Add some cheats And you Can now cheat...
There are no "button cheats" for any Pokemon game.
