NCA-NSP-XCI to LayeredFS Extractor Switch

NCA-NSP-XCI to LayeredFS extractor and also includes update merging code.

Note: This tool (script) is deprecated. It is recommended to use DBI, it is more complex but also can be used to extract application files.

User guide

Add your keys.ini to the folder to use.

Notes:

You still need to patch the main.npdm.
You will have to extract the biggest NCA for Cart2 games yourself, since its a different partition than the original Cart1 games. You can use XCI-Explorer-v1.2.2.1 for it.

Extracting NCA files:

nca from a base nsp (1-2-2): 1 NCA - 2 Extract Ecrypted NCA - 2 Romfs folder.
nca from an update nsp (decrypted base nca needed) (1-3-2): 1 NCA - 3 Update (base.nca + update.nca) - 2 Romfs folder.

Extracting NSP files:

extract a Base NSP (2-4): 2 eShop NSP - 4 Extract GAME Files
extract an Update NSP (2-5): 2 eShop NSP - 5 Extract UPDATE Files
To combine both copy everything from the update to the base files overwriting all.

Where to find title keys:

When you extract NSPs you get *.tik file that contain title key, also some XCI carts can have it but it's for update nca not for base game.
Open *.tik file with any Hex Editor and look at 0x180 where it's in 32 characters.

Notes on title key:

NCAs that come from XCI don't need title key except updates.
NCAs that come from NSP needs title key.
If Secure folder from XCI contains *.tik file then there should be update game NCA in there that needs title key.
