Hi Agustin, thanks for coming here. Is it just the master ball or how about the other cheats? For some players, switching to other cheat type fixes most issues, (Action replay to Codebreaker or vice versa). Your emulator also plays a huge role when using those cheats. I suggest using Myboy on Android or VBA on PC. Hope my suggestion helps.
Pokemon Flora Sky is a hacked version of Pokemon Emerald so you can use Pokemon Emerald Gameshark Codes or Action Replay Codes or CodeBreaker Codes for Pokemon Flora Sky. Pokemon Flora Sky Cheats help you to reduce your time playing this game and unlock all hard achievements.NOTE: Not recommended to use. You should play the game without codes.
