    I made this tutorial with my own *.cmd file. Tools for easy unpacking files are hard to find and didn't work for me.
    Tool doesn't support putting titlekey manually and never will.

    My pack is good for 5 situations:
    - Unpack only base game from *.NSP file
    - Unpack *.NSP base game patched with *.NSP update
    - Unpack only base game from *.XCI file
    - Unpack *.XCI base game patched with *.NSP update
    - Unpack *.XCI base game patched with *.NCA update that was already inside *.XCI

    What you need is the newest as possible "keys.txt" which can be found in Google or derived from your own Switch with Lockpick tool

    https://gbatemp.net/threads/switch-7-0-key-derivation-lockpick_rcm-payload.532916/
    As sharing keys is illegal, it cannot be uploaded to my package.

    Unpackv2.zip unlike Unpack.zip can find correct files in NSP to unpack automatically. It will crash if one NSP contains more than one game possible to launch from Home Menu.
    Additionally contains countermeasures in case when there will be different quantity than 1 *.tik file (Execution aborted) or 1 *.xml file (goes to manually drop NCA file).

    Download "Unpack.zip" or "Unpackv2.zip" from attachments and unpack it.
    Put "keys.txt" in the same folder as "Unpack.cmd".
    If your keys file is named "keys.ini" or "prod.keys", you need to rename it to "keys.txt".

    Tested on Windows 10.

    • For Unpack.zip
      1. Drop your game with *.NSP extension to "Unpack.cmd".
      Wait until window will be refreshed.
      In Unpack folder there is now "ExtractedNSP" folder with unpacked temporary files.

      2. If you don't have update, press ENTER without writing or dropping anything and go to point 3.

      2.1. Drop update file with *.NSP extension to command line.
      Press ENTER.
      Wait until window will be refreshed.
      In Unpack folder there is now "ExtractedNSPatch" folder with unpacked temporary files.

      2.2 Drop correct NCA file (probably the biggest one) from "ExtractedNSPatch" folder to command line.
      Press ENTER.

      3. Drop correct NCA file (probably the biggest one) from "ExtractedNSP" folder to command line.
      Press ENTER.

      4. Now wait until is finished. It will show you where tool unpacked game files.
      If you want to delete temporary files, press two times ENTER when asked. Otherwise close window.
    • For Unpack.zip
      1. Drop your game with *.XCI extension to "Unpack.cmd".
      Wait until window will be refreshed.
      In Unpack folder there is now "ExtractedXCI" folder with unpacked temporary files.

      2. If you have patch with *.NSP extension, go to 2.1.1. if it's with *.NCA extension (Custom XCIs) inside ExtractedXCI, go to point 2.2.1.
      If you don't have patch, press ENTER without writing or dropping anything and go to point 3.

      2.1.1 Drop update file with *.NSP extension to command line. Press ENTER.

      Press ENTER. Go to point 3.

      2.2.1 Write "1" and press ENTER.
      Drop correct NCA file (probably the second biggest file) from "ExtractedXCI" folder to command line.
      Press ENTER.

      3. Drop correct NCA file (probably the biggest one) from "ExtractedXCI" folder to command line.
