How do you copy a master ball on pokemon?
depends on which game. if its 1 of the older games you could put the desired pokemon into a pc, and when its saving, turn it off. I advise against it cause it can screw up the game. you could use a monster brain, and if you dont know what that is, or how 2 use it, tell me k?
you have to use Action Replay or Gameshark.
