If you were to install ticket files for them, can it be removed or is it permanent? Let's say if those tickets no longer work in the future or you have to send it in to Nintendo for whatever reason. Also, as of now I heard you have to install a ticket for each game in order for CIAngel to work, but I also heard you can download a file which makes all games work (wings.json?). I'm not exactly sure how these things work as of now. If someone can clear this up for me, that'll be awesome.
