I’ve done every thing you can do exept go to island 8 and 9.How do you go there? 
One wait for and Hotspot or Nintendo Event where they give the Mystery and Aurua ticket.
Two go to the store and get an action replay with Pokemon fire red codes and go to super cheats and find Navel Rock teleport code and Birth Isl teleport code
the second one was what I done and the codes work good. your welcome for the help.
