How do you clone the master ball pokemon crystal?

im pretty sure you give the master ball to a pokemon then put it in the daycare. with that done catch a ditto outside the daycare [make sure ethier the ditto is female and the pokemon is male or ditto is male and pokemon is female or else they wont like each other].then wait a while eventuly talk to daycare man or woman they say theres an egg take it run with it for a while it will hatch the hatched pokemon will have a nother master ball. [the breeded pokemon will be the same as the non ditto pokemon]. [u can check the stats of the egg and see how much longer you need to wait]. this should work as it does on firered and leif green. if it doesent try the oppisite gender of the ditto and the oppisite pokemon good luck!!!
