NSP stands for Nintendo Submission Package . It is the official digital format Nintendo uses for eShop games. Unlike XCI (cartridge dumps), an NSP is designed for installation to the Switch’s internal memory or SD card.
If you’re playing on a modded Switch or just updating your cartridge dump, grab this now. The exclusive visual fixes make the portable Arkham City experience finally match the original PC release.
Batman: Arkham City Nintendo Switch version is primarily delivered as part of the Batman: Arkham Trilogy
