Go to data management and in system setings and see if your games are there. If they are greyed out it may be as simple as installing the tickets with ciangel.
in data management software all I have are Luma3DS Updater, hblauncher_loader v1.2, and FBI.
in Extra data I have some of the old stuff 9like face raiders, pkmn shuffle/rumble world, eshop, plaza, pokebank and etrian odyssey (but thats just like saved data andn ot actual game right?)
