Where do you get master balls in Pokemon Sapphire?

Answer 1

In Lilycove (team aqua) Hideout go to the boss room and in the top-left corner there are 4 Pokeballs (two are Voltorbs or Electrodes) but to avoid that hug the left wall and there will be a nugget and then the Master ball. and at the lotto in lillycove if all numbers match you get a master ball.

Or if you are playing gba press f2 on your keyboard then type on decription: Masterball code

Click codebracker

Then type in the code section: DCEEEC34AFEADC26

Then check your PC and take as much master balls as you like

for vba its the pretty much the same thing but you click cheats then cheat list then click codebreaker then you type the description (description is the same as gba) then you type the code (pretty much the same as gba) then you go to your PC then you get unlimited master balls.
