There is no way to get masterballs from a cheat, unless you got pc, or if you got action replay. I hope i helped you.

Yes, GameShark codes work in Pokemon Emerald for the PC. My codes work when I try them.
First use the masterball in PC cheat DCEEEC34AFEADC26Then use the infinite item code so 1 masterball never runs outA1D75FBCCEC709E8
99 Masterballs in your PC: DCEEEC34AFEADC26 P.S. It may not work (only for rudy)
i don't know you can get it in the pc, but (for gameshark) you can buy them in the shops with this cheat 82005274 0001
