An NSP (Nintendo Submission Package) is the primary distribution format for Nintendo Switch digital games, updates, and DLC. It is a containerized, encrypted, and signed archive derived from the NCAP (Nintendo Content Archive) format. Unlike the XCI (cartridge image) format, NSPs are designed for digital distribution via the eShop and installation to internal storage or an SD card. This report dissects the NSP’s internal structure, cryptographic protections, metadata, and content organization.

The NSP uses (Partition File System 0) as the outer packaging. Its structure:

An NSP file is essentially a container that holds all the necessary data to install and run a digital title on a Nintendo Switch console. inside switch nsp

When installing an NSP via system menu or third-party tools (e.g., Tinfoil, Goldleaf), the ticket is validated against the console’s stored keys.

Each of these is an file – a separate encrypted container inside the outer NSP.

This design ensures that only authorized consoles with proper title keys and hardware-rooted master keys can decrypt and run the game. For modders, researchers, and homebrew developers, breaking into an NSP requires key extraction from a physical console – making the format secure against casual inspection but well-understood through hardware-based recovery methods.

The homebrew community has shown interest in NSP files, particularly in how they can be used to distribute homebrew applications. Tools and guides exist that allow developers to create and install NSP files for homebrew purposes. However, this is a niche area and can involve risks, including the potential for bricking the console or violating Nintendo's terms of service.
