Ok so I beat the rocket base in Veilstone and he said he is going to Mt.Coronet to activate Dialga and I tryed going tp the way to the snow town but It doesn't work. Can someone help me with this???
you need not to go to snowpoint city or the town with snow. what you need is to enter mt. coronet and find your way to the top by climbing the stairs. i'm not sure on what entrance you need to go.. but keep on trying
