How is the Power Berry duplication glitch accomplished and is it system specific?

The glitch is done by picking up a power berry at the same time you do one of the tired animations. Then you move to another screen and press A so that a clone of yourself appears. The next time you change screens, you should have a power berry floating above your head, any items you eat on this screen will count as a power berry, but once you eat at least one and change screens it will disappear. As for whether or not it is system specific, I don't know, but I think it is unlikely.

Hmm, I wonder if we could make a meme categor, Berry%, or something, where you basically just plant a ton of crops on your farm and duplicate power berries until your each 999 or so ranch score with just berries XD
