How to Duplicate a Master Ball in Pokemon Crystal

In Pokémon Crystal Version, you can use the Master Ball to automatically catch any Pokémon. The Master Ball gives you a completely guaranteed capture, making it a useful tool for catching rare legendary Pokémon such as Lugia or Suicune. You’ll only get one Master Ball in the natural course of the game, but fortunately you can exploit a glitch in the game’s design to duplicate the Master Ball an infinite number of times.

Instructions

1. Get the Master Ball from Professor Elm after collecting all eight gym badges in Johto.

2. Head to any Pokémon Center. Approach the PC in the upper right corner of the room. Stand directly in front of the PC and save your game.

3. Attach the Master Ball to any Pokémon in your party.

4. Press “A” to access the PC, and then select “Bill’s PC.” Select an empty box and deposit the Pokémon holding the Master Ball into the empty box.

5. Select “Change Boxes” and the game will automatically start to save. Immediately after the words “Saving the game…” appear on screen, turn off your Game Boy Color.

6. Turn your Game Boy Color back on and load your save file. You will find two copies of the Pokémon: one in the box, and one in your party. Each will have a copy of the Master Ball.

Tips & Warnings

• You can deposit five Pokémon holding Master Balls to duplicate five at a time.

• You could potentially corrupt your save file and lose your game data, if you fail to execute the timing properly in Step 5.
