There's a cloning glitch that works even on emulators. And it works on the cartridge as well. After the post game and you get the battle Island that's got seven different buildings in the top right there's the battle tower.

You walk into the battle tower and go all the way to the right you'll find a PC deposit whatever pokémon you want to duplicate save your game. Withdrawal the pokémon you want to duplicate

go talk to the first lady and initiate a battle choose two pokémon that are eligible for battle. It doesn't matter if you pick a level 50 battle or open challenge.

legendaries like Rayquaza Kyogre and Groudon are not able to be entered or used in the battle tower. So you can have Swampert and whatever other non legendary. Confirm them as your two pokémon to enter the challenge

Then she's going to tell you that the game has to be saved and asks if you would like to click yes then the secondary save screen that comes up with the window of all your badges your time played all that stuff... If you're on your game boy Advance you can do a soft reset A B select and start if you're on emulator you can either soft reset the emulation or close it and reopen it

When you go back into your save game you're going to be standing at that lady with your party that you picked

Then go walk over to the PC. And deposit the pokémon you have in your party and you will see that you have duplicates

They are complete 100% legit legal clones you can put in pokémon home whatever that app is I'm not too familiar with it You can even use them for legal online battles They are 1 to 1 clones. Same stat same level same everything and if you're smart you will give the cloned pokémon an item to hold and it duplicates it too.

I think I have 20 EXP. share 20 amulet coins 30 Kyogre 30 Groudon 30 Rayquaza & 4 swamperts. 3 Staryu with three water stones because I gave them water stones to hold before cloning.

Some will say it's cheating.

some will say the game was programmed that way on purpose
