So I have two copies of the game, one that I got recently and one I've had for years, and I have two 3DS systems. I use my New 3DS XL for all my games except my second copy of ACNL which I use the Black Friday new 3ds to play but I find it annoying having two separate systems just to play one game. If I decide to play my second copy of ACNL on my 3ds will that affect the street pass on them? Also if I TT on one will the other also TT? And Finally will having the update on one cartridge update the other one?
