You have to use action replay.
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.

Have a friend trade you a Pokemon holding the master ball they received.
maybe
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.
No. You can only get one master ball. But you can get one from a friend or if you have a GBA game like emerald, leafgreen, ruby like those and have a master ball on your GBA save make a Pokemon hold it then in pearl or diamond go to Pal Park and choose the Pokemon with the master ball and 5 others from your box capture all of the Pokemon then you will have theMaster Ball
if you clone a masterball
you make a lot of money and buy another one. knock knock knock

Yes, you have to cheat or get match all five numbers in the lottery or trade with someone who has a master ball.
