you get the master ball by going to the galactic HQ in veilstone. once you have got all the way to Cyrus's office you will battle him and, if you win he will give you the master ball.
hope this helps.

You are going to have to either use a cheat or catch it with a Master ball.
trade a friend a pokemon and his pokemon holding a master ball
In Pokemon Diamond, Pearl and Platinum you can get one master ball from Master Cyrus. To get more, you have to cheat using a Action Replay DS or DSI, or you can trade Pokemon with your friends and receive master balls from the Pokemon that they traded.

There are no "Cheats" for pokemon. Only hacking tools or glitches like cloning, action replay codes etc.
