Q: <strong>Is NSZ the same as NSP?</strong>

Although they are closely related. NSP is the standard Nintendo Switch digital game package used for eShop titles, updates, and DLC. NSZ , on the other hand, is a compressed version of NSP . It contains the same game data but uses compression to reduce file size. While NSZ saves storage space, it is not supported by all emulators or tools, which is why many users prefer converting NSZ back to NSP for better compatibility and stability.

Question 1

Does converting the file affect the game quality?

Accepted Answer

NSZ is a "lossless" compression format, similar to a ZIP file on your computer. When you decompress it back to NSP, the resulting data is bit-for-bit identical to the original uncompressed game file. You will get the same graphics, audio, and gameplay experience.

Question 3

Can Nintendo Switch run NSZ files?

Accepted Answer

The official Switch firmware only supports standard formats like NSP and XCI. NSZ is a community-created compressed format designed mainly for emulators and storage efficiency. To use an NSZ file, it must first be decompressed and converted to NSP using proper tools and valid keys. Once converted, it can be installed like any normal NSP file.

Question 4

Can I play NSP files on Nintendo Switch?

Accepted Answer

NSP is the native digital package format for the Switch, meaning legally purchased eShop games are installed as NSP internally. However, installing external NSP files requires a modified (custom firmware) Switch and legally owned backups. On emulators like Ryujinx, Yuzu, Suyu, or Sudachi, NSP files are fully supported and are often the most stable format for gameplay, updates, and DLC.
