You have to get a codebreaker and put in the master code. Then you have to find the code for infinite masterballs on the computer.
you have to use cheat codes ok hopes this helps
Use a Gameshark (I lost my Gameshark code for it)
You need a Action replay for gameboy.
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.
