EDIT: THIS TUTORIAL IS OUTDATED! NO SUPPORT!

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 best results move your game files to unpack folder.

I'm trying to run hactool.exe but it immediately closes after opening it, not even enough time to see what the command prompt window says.

 

[Dark9Volt]

I'm trying to get game files from WarioWare: Get It Together! NSP file. - And i've got this:

>"Key ( ) must be 32 hex digits!"

What should i do?

 

[Impossible_Igntiz]

This program needs to be updated, i'm trying to extract Sakura Swim Club and it refuses to dump every single file/folders in it's section0 directory.

 

[Digika]

is this the best and the only tools that allow to unpack NSP/XCI?

Are there any authoring/repacking tools as well?

 

[Melly]

Thank you so, so much for this tool! I was able to extract the files I needed using it.

 

[Imancol]

Just use nsp builder

I remember using this tool to repackage after joining Base + Update in The Witcher 3. But notice that when I start the game the logo loading screen stays and it is removed if I go Home and return to the game. Will there be any solution?

 

[Geror128]

Attempt №2.
Already do not hope that someone sits here and answer me (unless delete my comment.) But I'll try my luck. Who can tell me what to do if V1 immediately asks for NCA after I put the game + patch, and does not want to unpack the NSP?

I watched the process more complicated, good tutorial.
