If they aren't Causing problems then no, but if and Only IF the problem persists then you need to try a system format.
Don't do that if you haven't tried BBM and also what firmware are u on that could cause problems too.
Hmmm Did anything go wrong during your installation of a9lh, and yea i say 11.0 guess that isn't the problem.
Question did you make a dbs folder in the Nintendo 3ds/A lot of Number,letters/More numbers and letters
tell me if this confuses you. It should go example: Nintendo 3ds/7d54635271hu/hsgjslsliuhr936474/dbs
and in that dbs folder make a import and a title.db file just make a .txt file and name it Import.db and Title.db
I checked and I already have a dbs file, should I delete it?
Anyway, could it be linked to the fact that even if in system settings there were games like SM3DL or Pokémon Shuffle, I had not those in games in my home menu?
