Wait for the game to momentarily freeze and restart the game when the screen changes. Talk to the woman on the far-right, select a mode, select a party, choose Yes. Turn the PC back on and withdraw the Pokémon. Give the Master Ball to a Pokémon and deposit it to a box on Lanette's PC in the Battle Tower.

Wait for the game to momentarily freeze and restart the game when the screen changes (I've tried the soft reset and simply turning off the handheld). Talk to the woman on the far-right, select a mode (I've tried both), select the party, choose Yes. Go back to the Move Items screen, take the Master Ball, and put it back in the Bag. Go to the Battle Tower PC, select Lanette's PC, select Move Items, and give the Master Ball to a Pokémon. These are the two ways I've tried so far. The main thing I'm trying to do is get a few Master Balls.

I'm using the steps outlined on the forum and I've watched a few Youtube videos just to make sure I've got it right, but it still won't work. I just finished the campaign of Pokémon Emerald last night and I decided to give the cloning/duplication glitch a shot, but I absolutely cannot get it to work and I don't know why.
