Do not use action replay because it puts a massive virus on your nintendo DS, it crashes alot, it freezes when you press start, when you draw somwhere it draws in the wrong place.if this happens to you please send me a comment and ask what ever you like

This is what you need to do if it does have a virus, delete all your memory on every single game you have (yes even nintendogs, oh did i cry) and games what you can't delete like sims2, yoshi touch and go, super mario 64 ds (because you cant delete the memory on the minigames) then send your DS back and get a new one, and it work properly. (this is my 3rd one i sent back in)

hope this helped, answer me if there is any problems
