: You can purchase "Dying Light: Platinum Edition" directly from the Nintendo eShop on your Nintendo Switch console. This ensures you're getting a legitimate copy of the game.

However, I can put together a useful explaining:

If you have a modded Switch and only want the file for legitimate homebrew or backup purposes (of a game you already own), you’ll need to dump your own cartridge — not download a pre‑made NSP from a stranger online.

: NSP files are typically associated with pirated or cracked versions of Switch games, often discussed in forums or communities focused on Nintendo Switch homebrew and piracy.
