Does anybody knows the action replay code for Pokemon Pearl that gives you wild chiny pokemon?

I want the cheats for Pearl that gives you chiny wild pokemon. My brother has Diamond, and I just start playing Pearl. Most of his cheats won't work for Pearl. The only thing I'm desperately in need of is catching chiny Pokemon. I have Pokemon Modifier, Pk Lv Max, All Item, Pokedex Completion, but I need this last one. Chiny Pokemon.
