When I was looking at the base on zangoose, it said Rt 208 and 210?
If you click the links it takes you to the route pages: http://pokemondb.net/location/sinnoh-route-208 http://pokemondb.net/location/sinnoh-route-210
As it says on those pages, you need to have a copy of Pokemon Ruby on GBA and put it in the GBA slot on you DS or DS Lite. (Doesn't work with DSi or later.)
