@matana elaborate? have you already installed pirated games on your sysnand? if so, then an emunand is pointless and you're going to have to stay offline forever on your sysnand. if you have a backup of your sysnand before you put anything on it then you can roll back to it and then get an emunand for piracy.

emunand can be useful if you're making some drastic changes, there is a switch mod that adds a complete menu overlay, there are overclock settings you can mess around with, etc. so having a separate environment could be nice for some use cases other than just piracy.
