The Pokémon Cloning method in Generation II was the first one discovered and is thus more well-known than [[Pokémon Cloning (Generation I)|the method for Generation I]].▼

1. Save the game.

Another possibility is that there will be two of the Pokémon in the Box. {{clarify}}
==Notes==
* 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.
==Explanation==
Saving the game for changing the box is handled a little differently than saving the game normally. It consists of three steps:<ref>[https://github.com/pret/pokegold/blob/dc77fcf2c7b28222dabfdfbbe5a409d38ff29e13/engine/menus/save.asm#L40-L61 The function to save the game for changing the box on Gold/Silver] and [https://github.com/pret/pokecrystal/blob/8c6242a1524f3e757f6430e8f729133f9bd76c96/engine/menus/save.asm#L39-L61 on Crystal]. Note that the behavior of <code>SavingDontTurnOffThePower</code> is different on the two versions: On Gold/Silver, the function not only prints the "Saving..." text but is also responsible for [https://github.com/pret/pokegold/blob/dc77fcf2c7b28222dabfdfbbe5a409d38ff29e13/engine/menus/save.asm#L249 actually saving the game afterwards], but on Crystal, actually saving the game happens as [https://github.com/pret/pokecrystal/blob/8c6242a1524f3e757f6430e8f729133f9bd76c96/engine/menus/save.asm#L241-L242 the first thing in the <code>SavedTheGame</code> function] instead (before the same function prints the "<PLAYER> saved the game!" text). This causes the timing windows for cloning, and especially [[Bad clone glitch|bad cloning]], to be different on those versions.</ref>
# The contents of the active box (before changing) is saved to the SRAM.
# The number of the active box changes, and the contents of the new box is loaded from the SRAM.
# The game is saved as normal.
If the game is reset after step 1 has finished but before step 3 starts, then the contents of the active box is updated, but the party (a part of the main game data) is not, resulting in Pokémon cloning.
Although the save file is protected by a 16-bit checksum and a backup copy, they only apply to the main game data, so this glitch is not prevented. Furthermore, this means that even if step 3 has started, as long as the game hasn't finished writing the main save file, the main save file would likely be detected as corrupt and the backup would be used instead, resulting in successful cloning anyway.
Overall, when using the change box method, the timing window to get a good clone is rather lenient:
* On Crystal, the window is about 9–10 frames, beginning just a moment after the "SAVING... DON'T TURN OFF THE POWER." text is fully printed.
* On Gold/Silver, the printing of the entire "SAVING... DON'T TURN OFF THE POWER." text, as well as a 16-frame delay afterwards, happens within the timing window, in addition to the aforementioned 9–10 frames.
Resetting a moment earlier than the beginning of this timing window may end up interrupting step 1 and result in the [[bad clone glitch]], which is much harder to intentionally execute due to a smaller timing window.
