For those interested in digital game distribution, you may have come across NSP and XCI files. NSP (Nintendo Submission Package) and XCI (eShop file format) are file formats used for digital distribution of Nintendo games. NSP is the official format used by the Nintendo eShop, while XCI is a third-party format used for game distribution.

If you're interested in Pokémon Shield, I recommend purchasing it through the official Nintendo eShop or other legitimate retailers. This way, you can ensure you're getting a safe, supported, and legitimate copy of the game.
