where do you get the second master ball in Pokemon pearl
you have to clone that Pokemon holding a master ball

You can copy a master ball on Pokemon Emerald by having one of your friends that has one sign on to their ds and connect the two. Then they can give it to you in the Pokemon center.
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.
There is no second master ball in any game.
No.
capture legendary Pokemon like rayquaza.
You cannot find a second master ball however you can trade Pokemon to get another Pokemon with a master ball or use an action replay
You can't do that unless you have emerald. then you can clone the master ball.
Get a ruby,sapphire, or second emerald get the masterball in that one and trade it over with your second game starter and do it again this gets you masterballs and the other starters
