So when transferring system data from my 3DS to my New 3DS, I didn't quite understand what was going to be wiped and what wasn't, and I ended up reformatting or wiping my SD card in my old 3DS.
Unknowing that I lost some important data I wanted (Animal Crossing save data from the downloadable game, and Mii Plaza data)
I've since tried to run some recovery programs on the formatted or wiped (not sure how the old system deals with SD cards after a system transfer) and of course it all looks like jibberish and I don't know what is actual game stuff or what.
I guess my question is: Is there any way I can recover my animal crossing or mii plaza data? I had A LOT of ACNL stuff, and many puzzle pieces and mini game progress I really hope isn't gone forever.... Any help is appreciated, sorry if my explanation sucks.
