So, I'm looking to buy the new LoZ 3DS XL and selling my old one. I'm still a little unclear as to how system transfer works. What I'm wondering is what would result from performing a system transfer to it, since it has the game preloaded onto it? Does performing a system transfer completely wipe the new system and replace the data with that of the old system, effectively removing LoZ from the new one? Or would it just add my old data onto the new system and still leave LoZ on it?
