This is the "Nintendo Submission Package." It’s the format the Switch uses to install digital content.
An .NSP file is essentially a package containing the game’s content, tickets, and metadata, designed to be installed directly onto the Switch’s internal memory (or an SD card) just like an official download from the Nintendo eShop. When a user searches for "NSPUpdate," they are looking for a patch file—a standalone package that updates the game version without requiring the base cartridge dump. It is the cleanest, most digital-native way to modify the game data.
