Yes in the Goldenrod Lottery Corner if your Pokemon ID completely matches the lucky # you get 1 master ball, caution this will never happen unless you trade with Steven Stone, people in the union room, and the GTS. Hope this helped.:)
Not without AR or trading it from another game.
From what it looks like now, you can't get more then 1 Master Ball in any Pokemon game. However, you can trade them over to another Pokemon game. Example : If you need a Master Ball on Platinum, you can still trade it over from Diamond and/or Pearl, or even from HeartGold and SoulSilver. I'm afraid that's the only option to get more then 1 Master Ball.
Well, as a Master Ball is extremely rare and it is has a 500% catch rate, there is only ONE Master Ball in the whole game so you can't get a Master Ball more than once without cheating!
no
you will only be given one master ball.
no there is not
Win the goldenrod lottery.
Have a friend trade you a Pokemon holding the master ball they received.
maybe
Yes! But you've gotta be extremely lucky. Go to the lottery corner (Goldenrod Radio Tower) and cross your fingers. Or you could hack the game...
You can't get another master ball in emerald because there's no one will give you the master ball just the general will give you that.
You have to use action replay.
