If you actually meant a good paper on (ignoring “NSP”), consider:
This brings us to the technical component of the query: the file extension ".nsp." Standing for "Nintendo Submission Package," an NSP file is essentially the format Nintendo uses to distribute games digitally through the eShop. It is a container that holds the game data, executable files, and metadata. In the context of the hacking and homebrew community, an "nsp" file represents a dumped or ripped copy of a Switch game that can be installed on a modified console or run via PC emulators.
The term refers to a Nintendo Submission Package, the standard file format used for digital software on the Nintendo Switch.
