you can't get 999 master ballsdon't waste it on dimond or pearl they can be caght with a ultra ball OK.
Buy an action replay works for Pokemon pearl dimond and platinum
You get one and only one after you defeat the team galactic boss or if you trade.
Getting master balls without cheating in Pokemon DP is very hard. The only ways are: to win the lottery in Jubilife City, or receive a Pokemon that has a master ball from trading. I have 2 master balls in my game. I traded with a person who had a Pokemon with a master ball.
The only way to get another master ball in Pokemon dimond whithout cheating is by giving a Pokemon a master ball as an item in another game and trading that Pokemon to your Pokemon dimond game and take the master ball then you can use it. Or you can get an action replay at www.amizon.com for $20.00 and find the master ball cheat for it then you can get lots of master balls all the time it realy works try it.
Buy them stupid
As many as you want, you can buy them.
You cannot duplicate Master Balls in any Pokemon game.
There is only one master ball in Pokemon diamond. But there is a cheat for getting a WHOLE lot more. Look it up at how do you get 98 master balls? I don't know where the master ball is I think it's in a team galatic headquarters.
its a long one bhjih377894gy4hnfjfbhdfndckrjooe93424i43uu3u5ffannklkjnarfcas981345y34udbaqe
