NSP stands for Nintendo Submission Package. This is the direct, unaltered format used by Nintendo’s eShop. When you download a game digitally from the Nintendo Store, you are getting an NSP. These files are encrypted and signed. For backup purposes (via custom firmware like Atmosphere), an NSP is considered the gold standard because it is a 1:1 replica of the digital game.
Not every Switch game benefits equally from compression, but this title is unique for several reasons.
1. The Dual Nature of the Game Super Mario 3D World is a linear, level-based platformer.
