This is only a theory and I would like to know if it would work or not
Having a friend with X or Y and a 3ds to use, On the one with the Pokemon to clone take the 3ds's SD card put in a computer and click all the top options, when you find the backup save file (that's what it is right?) copy it to your computer. Trade the Pokemon you want to clone to the other 3ds (possibly multiple if this works :D) then switch off the 3ds that traded the Pokemon and put your SD card back into your computer and replace the new file with the old (before the trade happened) And when you turn on the 3ds and open the Pokemon version and you should have the Pokemon that were on the game BEFORE the trades therefor you have cloned, right?
Would this work?
What are possible consequences to what I am doing?
Am I compleatly wrong about it being a backup file?
If you do not know what I mean about the file and the backup file (there both the same thing) See the video, when he goes on his computer he will step by step you through to the file. And obviously not online, game sync will destroy this.
