The general process is:
Dump the game files directly to your SD card using nxdumptool. Update data can only be processed if the base game is available, because they share the same filesystem. DLCs don't, so they have to be dumped separately.
# Dump the base version NCA of the game.
# Dump the update NCA.
# Extract the romfs to get a copy of the content files.


'''Warning''': Running homebrew on the Switch can get you banned from Nintendo online services if you aren't careful. If you do not want to leave any traces, turn on airplane mode, back up your NAND '''before running any homebrew''' and do not ever go online before you have restored the backup.

=== Prerequisites ===
=== Prerequisites ===
* [https://github.com/SciresM/hactool hactool]
* [https://github.com/DarkMatterCore/nxdumptool nxdumptool].
* [https://github.com/DarkMatterCore/nxdumptool nxdumptool]
* Keys file generated using [https://github.com/shchmue/Lockpick_RCM Lockpick_RCM], located at <code>sdmc:/switch/prod.keys</code>. Run the payload on your console through RCM in order to dump the keys needed by nxdumptool to decrypt contents.
* Keys (see below)
*# Run [https://github.com/shchmue/Lockpick_RCM LockpickRCM] on your console in order to dump keys that are required to decrypt contents (or get a copy of the keys manually).
*# Copy the keys file from your SD to <code>$HOME/.switch/prod.keys</code>.


'''In the instructions below, every time you are dumping a NSP, turn on the "Remove console specific data" and "Generate ticket-less dump" options (to make extraction easier).'''
=== Dumping game files ===
* On your Switch, open nxdumptool. Afterwards:
*# '''If you have the gamecard''': Select <code>Dump gamecard content</code>.
*# '''If you have the eShop version''': Select <code>Dump SD card / eMMC content</code>, then select BotW.
* Select <code>RomFS options</code>.
* Highlight the <code>Use update/DLC</code> option and use the left/right buttons to cycle through the available updates/DLCs for the game.
*# '''If you have no available updates/DLCs''', this option won't appear. You'll only be able to dump the files from the non-updated base game (which is the same to just leaving this option set to <code>No</code>).
*# Updates are tagged as <code>(UPD)</code>, and they use <code>01007EF00011E800</code> as their ID. v786432 corresponds to BotW v1.6.0 update.
*# DLCs are tagged as <code>(DLC)</code>. <code>01007EF00011F001</code> and <code>01007EF00011F002</code> are the known IDs for the existent BotW DLCs.
* Select <code>RomFS section data dump</code> and wait for the process to finish. This will dump the internal filesystem from the selected update/DLC to the inserted SD card.


=== Dumping the base NCA ===
Just like it was previously mentioned, updates share their filesystem data with the base game, so dumping the RomFS from an update is equivalent to dumping the whole filesystem from the updated game data. In other words, it isn't necessary to dump the base game filesystem separately if you choose an update.
Because of how updates work on Switch, the base NCA must be dumped even if you're only interested in 1.6.0.


* On your Switch, open nxdumptool.
DLCs, on the other hand, must be dumped separately.
* '''If you have the game card''': Select "Dump gamecard content".
* '''If you have the eShop version''': Select "Dump SD card / eMMC content". Select BotW.
* Select "NSP dump". If asked to, select "Dump base application NSP".
* Copy the NSP to a computer, then extract it by running the command <code>hactool -t pfs0 [path to the NSP] --outdir [folder where to place the NCAs]</code> {{CLI help}}. The main NCA will be found in the folder you've told hactool to extract the files to, called <code>efecb2d6befccddc928e44416dbdee38.nca</code>.


=== Dumping the update ===
When you're done, you'll be able to find the output dumps in <code>sdmc:/switch/nxdumptool/RomFS</code>.
* On your Switch, open nxdumptool again.
* '''If you have a <1.6.0 game card''':
** Select "Dump SD card / eMMC content".
** Press Y to "dump installed content with missing base application".
** Select 01007EF00011E800 (this is the BotW update title).
** Select "Start NSP dump process".
* '''If you have a 1.6.0 game card''':
** Select "Dump gamecard content".
** Select "NSP dump", then select "Dump installed update NSP".
* '''If you have the eShop version''':
** Select "Dump SD card / eMMC content". Select BotW.
** Select "NSP dump", then select "Dump installed update NSP".
* Copy the NSP to a computer, then extract it by running the command <code>hactool -t pfs0 [path to the NSP] --outdir [folder where to place the NCAs]</code> {{CLI help}}. You now have the update NCA (see [[Versions]] for NCA hashes).
 
=== Extracting the romfs ===
Now that you have the base NCA and the update NCA, you can extract the romfs (which contains all [[content]] files) by running the command {{CLI help}}:
 
hactool -x -t nca path/to/update.nca  --basenca path/to/base.nca --romfsdir where/to/extract/the/romfs
 
To extract the exefs (which contains the [[executable]] and SDK libraries):
 
hactool -x -t nca path/to/update.nca  --basenca path/to/base.nca --exefsdir where/to/extract/the/exefs
 
=== Dumping the DLC ===
The [[DLC]] can be dumped by following the same procedure.
 
* '''If you have a game card''':
** Select "Dump SD card / eMMC content".
** Press Y to "dump installed content with missing base application".
** Select 01007EF00011F001 (this is the main BotW DLC title).
** Select "NSP dump".
* '''If you have the eShop version''':
** Select "Dump SD card / eMMC content". Select BotW.
** Select "Dump installed DLC NSP".
* Copy the NSP to a computer, then extract it by running the command <code>hactool -t pfs0 [path to the NSP] --outdir [folder where to place the NCAs]</code> {{CLI help}}. You now have the DLC NCA.
* Extract the exefs and the romfs by following the instructions in the previous section.
