The cheats for the ds are only for the da sadly, because the 3ds still doesn't have any cheats which really sucks. There's nothing we can really do about it though, since the system is still sort of new there isn't any cheats for it. I've looked up cheats for the games I have for the 3ds and there's none at all, I go and look for the ones on the ds and there is a lot. So I'm thinking no one has cracked the system yet. Hope this helps
