>>33477949>Another cloning method present in the early Pokémon games involved the exploit of the Pokémon Storage System and the fact that the game needed to save every time a Box was changed. During the saving that takes place when switching the Box, first the Pokémon data on all the PC Boxes is saved, and then the Pokémon data on the player's party. If some Pokémon are deposited in the PC before switching the Box, interrupting the saving process (turning the power off) at the right moment (ideally, before the "S" in the dialog Box appears but after the Box has appeared) causes said Pokémon to be present both in the Box and the player's party. This method, unlike the trade method, allows the player to clone up to five Pokémon at the same time, as well as in Generation II, clone items by making the cloned Pokémon hold items before cloning it.If the glitch is used with a game attached to Pokémon Stadium 2, there is a chance of getting strange glitch Pokémon. If the player withdraws a Pokémon and continues the cloning glitch, if the game is turned off at the right time, the cloned Pokémon will vanish and be replaced by a Pokémon with the same name, attack, and level as the Pokémon removed. Its sprite will be identical to the cloned Pokémon, but if sent into battle, it will appear as the withdrawn Pokémon. Its species name will be the same as the cloned Pokémon's and it will be able to learn all the TMs/HMs as the cloned Pokémon. However, it will evolve as the withdrawn Pokémon does.
This glitch may be used at the beginning of a game to obtain all three starter Pokémon.
