When you first enter team aqua's base at Lilycove City there is a door at the back. In the next room there are 2 warp panels use the one in the left. In the next room there will be a warp panel on the other side, just go around and then use it. The next room has lots of panels, when you first enter go to the one on the far left. Next use the middle one (you don't really have a choice). then the one on the left. On the next room use the far left NOT the center. You will now be in the room with the master ball. Top left is the maser ball, bottom left is another item, the other two are electrodes. Have Fun!!! (Voltex)
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 can't do that unless you have emerald. then you can clone the master ball.

In team aqua's base
Try harder
you can get a master ball in the team aqua hideout. Its in a room with four poke-balls.
you don't get the master ball from may in emerald, you get it in the team aqua/magma hideout in lilycove. that is the only way to get a master ball , unless you win the loto ticket drawing or use an actionreplay or gameshark.
