After you beaten the elite4 go to the battle fronteir and then to the battle tower.go to the pc and in any empty box,deposit the pokemons you want to clone. exit out of pc and save your game.withdraw the pokemon you just deposited and go talk to the lady behind the counter thats closest to your left.say ok to whatever she says and proceed as usual. now comes the tricky part-when she asks to save say yes. you will notice a 2-second freeze.at this point,DO NOT TURN OFF THE GAME CUZ IF YOU DO YOUR GAME MIGHT GET MESSED UP!!!. as soon as the game unfreezes, turn off and restart. then go to thepc again and you will find the pokemon you wanted to clone and the clone!
