game shark or action replay
ACTION REPLAY
you have to get master balls from professor roan
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.
There are none.
with acion replay
to get master balls..you must have a friend with action replay and trade you pokemons that will hold a master ball
You need action replay which you can find at game stop. then you scroll down and find more master balls. I don't have the code though, sorry but there is one of the wiki answers where it tells you the code. it's how do you get 98 master balls? I hope it helped!
you dont......you have to cheat but i am still trying to figure out how.
you can only get 1 master ball per game
You get it with an action replay
