What is the Action Replay DS cheat code for catching every Pokemon on Pokemon Diamond?

Here is a code for the wild Pokemon modifier. To activate it, press L and R together and you'll get 493 Master Balls, which represent the 493rd Pokedex entry. Toss the number of Master Balls you want away to get that Pokemon number. Tossing 492 Master Balls will give you Bulbasaur, since there will be 1 left. Hold down L and walk in the grass until the battle starts. To reset the number of Master Balls, just press L and R again.
