( ruby and sapphire) cheat code:description: fnifite masterballscode: 910C4AFB679BA66A
you have to use cheat codes ok hopes this helps
Use a Gameshark (I lost my Gameshark code for it)
action replay,finda shiny magmar,and trade
Use a cheating device. You can't get 99 masterballs on sapphire after catching the three regis without a cheating device. Also you din't need any regis to have 99 masterballs.
Well, first place in the lottery in sapphire awards you a masterball so trade with as many people as you can and check it every day! I have two masterballs thanks to this method! Not sure about pearl though.. if you have 2 or more you can give em to a ditto and another Pokemon and breed them. It worked for me i have 999 masterballs LOL
Level up the 3 regis to lvl 100 and u speak to a girl in lilycove department she gives you 99 masterballs. IT WORKED ON ME! :D
