For now this code is a bit 'dangerous', meaning if you don't follow the instructions the
game may crash. Enter the PC, and -if it's not already in there- put in a box the Pokémon
you wanna clone. Make sure you have at least one free slot. Now go in the 'Move Pokémon'
menu, press A on the Pokemon you wanna move, so the list of choice appear, and then put
the cursor on 'move' (it should be there by default), press 'Select+Start' while pressing
A to take the Pokémon, and while the Pokémon is 'in your hand', press R and then L (to
refresh the box) and voilà : your Pokémon will be cloned (it'll be in the box, and in
the hand) (fyi, not refreshing the box and dropping the Pokémon somewhere and trying to
take the cloned Pokémon WILL crash the game). Now that the box has been refreshed you can
drop the Pokémon anywhere, and repeat the process as much you want. People actually TRIED
THIS CODE AND IT ACTUALLY WORKS.
