You can either trade with someone who has a master ball or you can use a GameShark, there is only one master ball in a game
No you only get one master ball in Pokemon pearl. Sorry if this has upset you.
You can get one Master Ball in your GBA game and then migrate to Pokemon Pearl with a Pokemon holding the Master Ball.
cheating
I don't know. But i know how to get 999. You buy a DS cheat cartridge. You then put in Pokemon pearl THEN the cheat cartridge THEN you click on Pokemon pearl/diamond and then click on Pokemon 999 Master balls.
It is not possible to make master balls in Pokemon Pearl version. You can get one from beating Cyrus or in the Game Corner.

you get unlimited master balls by using action replay and put on master balls x999
to get master balls..you must have a friend with action replay and trade you pokemons that will hold a master ball

You can clone a Pokemon with the master ball or trade it to a friend and keep starting over until you're satisfied with the number of master balls.
