When it comes to a game like Animal Crossing: New Leaf, spending time on it is pretty much a requirement to get as much items as you can into your town. Assuming you get an item and you wish you can duplicate it, there’s a way to do it, although you are exploiting something that will not be too healthy for the game.
According to several people who tipped us several days ago, the duplication trick will require at least two people who are able to visit each other’s town online. If you have that requirement, let’s get to the process:
What you do is, drop the items off, then the host ends the game. As it saves, [the visitor turns] off the wireless via switch on 3DS. Bam. Duplicated. Cloned.
There’s one drawback if you want to do this. There’s a chance of messing up your save file by shutting off the wireless connection instantly. I don’t recommend in doing it but it works. So far, I have not messed up my game yet. If you want easy Bells, you can do this exploit and become rich by selling the most rarest item that you can duplicate. It’s a risky process but it’s worth it.
