NCA files are compressed archives (think zip) that contain game data, normally multiple NCA files can be extracted from a single XCI or NSP file.
These files store part of the game and are normally included inside other file formats. The recommended way of creating NSP files is to use the NX Dump Tool available on GitHubĮven although NSP is the format for Eshop games the application NX Dump Tool allows you to dump cartridges as NSP files.
