you need action replay
You need to use Action Replay DS, or a flashcart that supports Action Replay codes.
you cant get a code for 999 master balls only 900 and u activate it with select i think;~]
to activate it you must hold L+R and check your ball bag slot and they will be there. == ==
it requires an Action Replay. if you can activate without one, then i don't know how to
it depends what year the action replay is

Action Replay yourself a Master Ball.
there actually is an action replay for the xbox 360
It doesnt really matter when you do it, just dont do it when your on the actual berry screen. That can mess your game up pretty bad. Action Replay is awesome but you have to know how to use it.
you don't if you do all the other games on your action replay thing will be erased
