Nothing seems to be wrong with my AR on the menu. But when I get to the game none of the codes work. Do I need a new AR, or did Gamefreak make Soul silver AR proof?
its not Ar proof it is most likely an operator error in this case I would double check things and google a guide or something as AR talk is frowned upon here
Unfortunately, discussing AR Codes isn't allowed here, so the best answer for you right now is to probably do a bit of research online and figure out what the problem might be. Besides that, I'm just going to have to close this.
