first, you need to go to Verdanturf, where Wally lives with his Aunt and Uncle. To get there, go to Mauville, then when facing the gym, go left. And keep walking. But when you get to Verdanturf you will see a tent that is arch-shaped. Go in, and talk to the lady behind the desk. She will issue you a contest pass. Then you talk to her again and enter a contest. To go to contests in Slateport, or somewhere like that, you need to win first in Verdanturf, then get first in Fallabour, and then you can go to Slateport. But you must win the same Pokemon each time.
