You can only get one master ball in every authorized Pokemon game. Usually it is at the bad guys' HQ- e.g.Team Rocket, Team Galatic, Team Aqua; etc. But for a few versions, get it at Lottery Contest(if you win, but I doubt it), the easy way is to beat the bad guys' leader, in Platinum, beat Cyrus at Team Galatic's HQ. Try buying an R4 card(it's illegal) to download Platinum with cheats by Googling or Yahooing(internet Surfing, for better understanding). This will take a LOOOONG time, cos Platinum is well authorized and protected from copyright infringement. Try this website for Pokemon Guides- http://pokemon.marriland.com/ , it might help.
