The Pokémon cloning method in Generation II was among the first methods discovered and is arguably more well-known than the methods for Generation I.
- A Pokémon Gold, Silver, or Crystal Version cartridge.
- An empty Box on the PC.
- A Box that isn't full.
- Pokémon to be cloned.
- Another pokémon to keep in the party.
1. Deposit the Pokémon to be duplicated into a Box on the PC.
2. Switch to an empty box on the PC.
3. Log off of the PC, and save the game, but shut off the power three seconds after the game starts to say "SAVING...DO NOT TURN OFF THE POWER.".
When the game is turned back on, there should be the Pokémon deposited into the PC in your party, and it should also be in the Box where it was deposited.
Another possibility is that there will be two of the Pokémon in the Box.
- Up to 5 Pokémon can be duplicated at a time under normal circumstances.
- Items can be duplicated this way by making the cloned Pokémon hold the item to be cloned.
- This can possibly damage the PC, and cause Pokémon to disappear. Details on this and why this can happen is not known.
