And if they're just legal and not buyed from eshop? Like carts backupsIf you have a "clean" ticket.db ( I mean without tickets in the unkown folder ), make a backup of your current one(for safety reason, if you screw up) and replace it with your old "clean" one.
Then make sure you enter eShop and let it take it's time (it will take 1 or 2 mins) to re-install automatically all the legit tickets from the games you bought.
If the backup titles you have are legit and bought from eShop then you will have no problem
