Not without cheats, but you can win them at the lottery corner if you get first prize.
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.
I don't know where you could buy them, but you could get a friend to trade Pokemon over holding them.....
From what I know, You can't BUY master balls in Pokemon.
No, You have to use an AR code to buy Master Balls on any game.
You can't unless you buy a game shark or an action replay
I do belive there won't be that kind of cheat, but a smart, but long way is to buy a Pokemon pearl, or diamond, then cheating on that game, then trading and having those Pokemon have master balls.
Buy an action replay works for Pokemon pearl dimond and platinum
Master balls cannot be brought, only given or won.
You can't.

You can buy them in the Pokemart in Pastoria City
Master balls cannot be bought in any Pokemon game.
