They will be redownloadable.Sure we can! If we get a N3DS emunand update Ill be sure to create a NNID and delete some games just to see if theyre redownloadable again.
When you link for example A 3DS SSB edition (eur) with ssb pré included with a NNID.
The game will be in the redownloable game of your account.
I'm a ambassador and when i download the game on my first 3ds and i link my NNID all my ambassador games appear in the redownloadable soft. of my account.
And now on my 3DS xl i have all my Ambassador stuff. (i unllink my NNID with my previous 3ds because it's don't work now)
Ithinks it's the same thing for N3DS
