start you have to know how to copy pokemon. first things first move to a empty box in the pc. then deposit the pokemon you want to copy. then switch boxes. when the first priod appears turn off the game boy then turn it back on. the pokemon will be in both the box and in our party. deposit more pokemon for more than one copy.
for more masterballs or any other rare item just equip it to the pokemon that is going to be copied. and thats it.
