Things You'll Need
Instructions
Start a "New Game" from the main menu. Choose a gender, name your character and name your rival. The adventure will begin in your room in Pallet Town.
Exit the room through the stairs at the top-right corner and exit the house through the rug at the bottom of the screen.
Walk to the tall grass north of Pallet Town. Professor Oak will stop you. Follow him back to his lab to choose a starter Pokemon.
Press "Start" to save the game and bring up the game menu.
Press "A" next to the Pokeball of either Bulbasaur, Charmander or Squirtle to choose that character as your starter Pokemon.
Press "Start" and select "Pokemon" on the game menu. Select your starter Pokemon, highlight "Summary" and press "A" to view its status page. If there is a star next to its sprite and it has a different color than its usual form, it is a shiny Pokemon.
Reset your game if your starter Pokemon does not have a star next to its sprite and is not differently colored.
Repeat steps 5, 6 and 7 as necessary until you receive a shiny starter Pokemon.
