You get there almost immediately after the 8th badge. What I did was, as soon as i left the place where he comes in, I used the code went back in talked to him and caught Deoxys. I personally think it was worth it and it takes no effort whatsoever
I was wondering something. I cant find anything on where any of the pokemon are located, i dont know if thats a problem with the download or just because im on a mac. Can someone help?
