AR code to get to Hoenn in diamond and pearl

it is impossible to see on the map but you can ( if you own a action replay type in code walk everywhere) walk over seas to hoenn once again you can not see it. the screen might turn black but keep walking! Your game might glitch up and your game is screwed but it is worth it. It takes about two hours of walking and you have 2 keep the emerald in the bottom of the ds and try it. It really works! It is tested and it was told by one of my friends (maker of pokemon) that he put it in himself.
