no whoever answered this was a dork lol!, anyway, when you get the master ball and your at a point where you want to use it, with your first Pokemon tell it to throw the master ball, then with your second Pokemon GO to your pokeballs and scroll down to master ball and press X or Y and it will ask you which one to swith it with, switch it with any other ball and exit and attack with that Pokemon, when you throw it it will throw a masterball and when you go back to your pokeballs you will still have a master ball, its amazing!!!!!!!!!!
To get unlimited master balls in Emerald, first get a master ball,save it then beat the elite 4, go to the battle tower, and give one of your Pokemon the master ball put in your PC save then take it out talk you the first girl at the counter enter any Pokemon,while it's saving shut it off. Turn it on the go to your bag, there you will find 99 master balls, this also works for cloning Pokemon.

There is no legitimate way to obtain infinite master balls on Pokémon Sapphire. The only way would be to use an Action Replay.
