The only way I know of doing it is you have to have two 3ds or 1 3ds 1 2ds. You have to turn the power off at the same time on both systems. Though, PowerSave would be the easiest way, with just the DS's, it can 10 to 20 times to get 1 clone. (At least that's how long it took me and a friend)
The most "legit", non-patched way of cloning is through the two 3DS cloning glitch, which is easily found with a little searching. Other ways involve hacking your 3DS system and messing with the save file.. Highly don't recommend this as it can delete your file.
