I won it when i won the lotto
Go on with the story line.Eventualy you will get up to the part were your in the team galactic veilstone building, and after you face Cyrus in the building he will give you one master ball.If you are talking about more than that one the only other way is to have a Pokemon from another game hold one and trade it to yours (could be wrong),or you need an action replay.
i dont think u can get a next one'
i would use an action replay other than that i dont know
you first met Cyrus from team galactic in veilstone city but first go to the storage room and get the galactic head quarters key than you can go inside and go up some levels than you battle Cyrus.
The only way you can get more than one masterball on Pokemon ruby/saphirre is you compeate in the Pokemon lottery corner. In Pokemon emerald you can have a Pokemon hold a masterball and then clone it.After you beat Team Rocket in the Silph Co. building, then the president at the top floor, after you beat Giovanni, will give the Masterball to you.
well i dont know ive fbeat tem galatic and rocket id say the galatics harder
You have to get a cheat
no
yes you can but the only other way you can is by AR or you could get lucky at the pokemon lottery.
Other than the masterball try using a lot of ultra balls.
Go to superheats.com and use the AR code or trade som1's Pokemon that is holding the masterball
once you go through mt coronet's summit (beating galactic's boss and catching the legendary) go to sunyshore city, via route 22
