Hack the game otherwise, it's impossible.
i have tried multiple mobile versions of Pokemon and as far as i can tell no cloning will work therefore there is no way to duplicate anything as you normally have to put the masterball (or other item) on a Pokemon then clone. so without cloning there is no duplicating.
You cannot duplicate Master Balls in any Pokemon game.
duplicate or you use action replay and write down the code
Duplicate Pokemon with a masterball attached to them.
Duplicating master balls on Crystal at PlayR, is best learned by trial and error. Short cuts such as cheat codes are considered by consensus to be unethical and are strongly discouraged.
I don't know a master ball cheat, but there is a way of duplicating a Pokemon holding a master ball so u get two master balls and so on.
You can't have unlimited master balls although u can give the master ball to a Pokemon and duplicate it at battle frontier
You cannot duplicate master balls.
You can't but if you're really desperate, you can hack the game.
yes you can.because you can get another master ball at the lottery if your in first place.if you get lucky.The lottery is at lilycove city.you can do it every day.only once a day.ok.good luck
I dont think you can inless you have action replay. hope this helped
you cant without an action replay or internet cheats. they are most likely to be sold at the Game store in queensgate.!!!!!!!!!!!!!!
