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!!!
you use the hack
