This is a bit of a hypothetical for a friend who is thinking about upgrading to a New 3DS if a suitable bundle pops up that he likes.
In the past Nintendo has had bundled systems that come with a game preloaded onto the system's SD card. I know they occasionally give download codes instead, but just bare with me.
How would this work if you were transfering from an different 3DS to the one that has the preloaded game? Would you lose the promised bundled game since you're overwriting the SD card with your previous system's data?
Thanks in advance! Any answers would help ease my friend's mind should he want to upgrade and comes across this problem.
