How do you duplicate a Master Ball on Pokemon Emerald without using a cheat code?

Answer 1

In order to clone master balls and Pokemon, you must defeat the Elite Four. That's what everybody leaves out. Once you defeat it, you go to Littleroot Town. Your dad congratulates you and your mom asks you what BZZT dragon colour is. Then once you go out, Professor Birch and May gives you a S.S. Anne Ticket. Go to Slateport and go north (almost to the end of Slateport) then go right. Go into the building and get into the ship. Scott will appear and you can go to the Battle Frontier. Next go to the Battle Frontier and Scott appears and introduces to you the Battle Frontier. Next he'll give you a Frontier Pass. Go to the Battle Tower and then go to the PC there. Choose an empty box and put the Pokemon you want to clone there (for people who want to clone their Master Ball[for those people who haven't used it yet] give the Master Ball to a Pokemon). Then exit and save the game. Next, go to the PC again and take out the Pokemon you want to clone. Then go to the counter that is closest to you (for specific people, multi link battle counter) and talk to her. Challenge open level and choose your Pokemon. Make sure that the Pokemon you want to clone is the second Pokemon you choose. She then asks you to save. Press yes and there is a pause. That pause is when your Pokemon is being cloned. Then shut you game off when the "Are you sure you want to save?" screen comes on. Once you restart the game, you are at the counter where you clone your Pokemon. Go to the PC, then check the box you cloned your Pokemon with. Your cloned Pokemon (or Pokemon with Master Ball) is there. Have fun cloning!

P.S. There is a 80 percent chance it will succeed. 20 percent chance you fail. Don't put any Legendaries in your team. You will lose them. If I were you, I'd take those odds.
