NX Game Info


  • NSP, XCI, NRO and installed titles on Switch SD card
  • Game files structure (Scene Release, CDN Rip, Authoring Tool, Converted from other formats)

How to

NX Game Info uses prod.keys, title.keys and console.keys in the format as defined in and hac_versionlist.json from tagaya CDN server

  • prod.keys: Mandatory keys includes header_key, aes_kek_generation_source, aes_key_generation_source, key_area_key_application_source and master_key_00. Failing to provide these keys will make the application quit master_key_##, key_area_key_application_## and titlekek_## will also be necessary to decrypt titles with higher MasterKey requirement
  • title.keys: Optional, required for Permission check if .tik file not available
  • console.keys: Optional, sd_seed key required for Open SD Card feature
  • hac_versionlist.json: Optional, required for Latest Version feature

The application will look for these files at the following locations (other file locations will follow wherever prod.keys file was found)

  • Directory of the executable file (.exe) for Windows
  • $HOME/.switch e.g. C:\Users\yourname\.switch for Windows or /Users/yourname/.switch for macOS
