Dark world
This glitch was found in the japanese version and it seens that nintendo is fixing it for the english version,sorry.At the elite4,use surf in the front of one of the elite4 members door and you will be teleported to another dimesion that I call the "dark world".Use teleport,dig or fly to get out,i don't know exactily how but you will be able to go to a place where you can fight and catch the legendaries Sheimi(english name not confirmed) and Darkrai(english name probable the same).
