Does any1 know any cheats for Pokemon Diamond on DS, ?

Ohh, that's harsh losing all your data...

Anyway, I'm sorry to say but there isn't any apart from getting an action replay and putting codes in for it.

Other than that, back to the start! >.>

Aside from using an Action Replay, there are no cheats in Diamond.

well there are many different sites to choose from, if you wnat to find pokemon quickly and easily check out serebii.net pokedex it is well easy, I have used it myself, if you want a list of places or secret places check out en.wikipedia.org/wiki/Pokemon_Diamond and to get a walkthrough just type into google, Pokemon Diamond Walkthrough, I will be happy to trade a pokemon with him to help him, by the way how old is your son, I will trade a pokemon of his choice, I have all the pokemon apart from legandries so don't ask 4 a legendary, just post his friend code 2 me.

The best site to use is serebii.net it is ever so usefull, it may look a bit dull when you first see it but, it works!
