This term designates a specific file format associated with the Nintendo Switch game, Fire Emblem: Three Houses. The acronym “NSP” signifies a Nintendo Submission Package. This file type is essentially a container that packages the game data, updates, and downloadable content (DLC) necessary for the game to function on a modified or custom firmware Nintendo Switch console. This distinguishes it from legitimate, digitally purchased games from the Nintendo eShop, which have a different, DRM-protected format.
The appeal of these files stems primarily from the ability to bypass the official Nintendo distribution channels. This allows users to play the game without purchasing it through the eShop or owning a physical cartridge. This method is often associated with circumventing copyright restrictions and enabling access to the game without paying the licensing fees. The historical context revolves around the evolution of console hacking and the ongoing efforts to circumvent copyright protection measures implemented by game developers and console manufacturers.
