Instructions
Select a new file to begin your game. Leave your room and exit the house through the front door.
Go inside the laboratory and Professor Elm will allow you to choose from one of three Pokemon: Cyndaquil, Chikorita or Totodile. Choose any of the three to continue.
Go back to your house and speak with your mother. She will hand you the Pokegear.
Head north onto Route 29.
Continue west through Route 29 until you reach Cherrygrove City.
Talk to the old man outside of the Pokecenter in Cherrygrove City. He will give you running shoes. As you continue onto Route 30, the old man will stop you and give you a map add-on for your PokeGear.
Continue onto Route 30 to receive the Johto Pokedex from Professor Elm. Head back to Route 29 where you will be challenged by your rival. Defeat him and speak to Professor Elm's aid who will give you the first Pokeball and teach you how to catch Pokemon. From that point on, you will be able to purchase Pokeballs.
