Dump the game files directly to your PC 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.

=== Prerequisites ===
=== Dumping from a Switch ===
 
Dump the game files directly to your PC 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.
 
====Prerequisites====
* Keys file generated using [https://github.com/saneki/Lockpick_RCM/releases/ 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 file generated using [https://github.com/saneki/Lockpick_RCM/releases/ 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.
* [https://github.com/DarkMatterCore/nxdumptool/releases/tag/rewrite-prerelease nxdumptool rewrite] (get both <code>nxdt_host.7z</code> and <code>nxdt_rw_poc.nro</code>).
* [https://github.com/DarkMatterCore/nxdumptool/releases/tag/rewrite-prerelease nxdumptool rewrite] (get both <code>nxdt_host.7z</code> and <code>nxdt_rw_poc.nro</code>).
* [https://zadig.akeo.ie/ Zadig] to setup the driver (used for dumping through USB)
* [https://zadig.akeo.ie/ Zadig] to setup the driver (used for dumping through USB)


=== Dumping game files ===
====Setting up the driver====
 
# First, make sure to dump your keys by injecting the '''Lockpick_RCM''' payload and selecting "Dump title keys", then reboot to Atmosphère.
# Place nxdumptool rewrite (<code>nxdt_rw_poc.nro</code>) into the switch folder of your SD card, open it through the Homebrew Launcher, and plug the Switch to your computer with a USB cable.
# With nxdumptool open, launch Zadig on your computer
# Go to <code>Options</code> and make sure <code>List all devices</code> is checked -- if not, click that option.
# Using the dropdown list with USB devices, select the name of the NRO you launched on your Switch (e.g. <code>nxdt_rw_poc</code>).
# Change the <code>Driver</code> dropdown on the right to <code>libusbK</code> (the actual version number doesn't matter).
# Wait until the installation process finishes. If you did it correctly, Zadig should look like this:

====Dumping game files (romfs)====


* First, make sure to dump your keys by injecting the '''Lockpick_RCM''' payload and selecting "Dump title keys", then reboot to Atmosphère.
# Open the host app (.exe file extracted from <code>nxdt_host.7z</code>), and click <code>Start Server</code>
# If the UI says that the Switch is not detected, make sure that nxdt is running on your Switch, that you have setup the driver properly, and that you don't have a bad USB cable.
# On nxdumptool, navigate through the menu by selecting the following options:
## Go to <code>user titles menu</code>, then select <code>The Legend of Zelda: Breath of the Wild</code>
## Select the following options: <code>nca / nca fs dump options</code>  -> <code>dump base application</code> -> <code>Program #0</code> -> <code>FS section #2: RomFS</code>
## On the line with <code>use base/patch title</code>: select the installed update
## On the line with <code>output storage</code>: select <code>usb host (pc)</code>
## Select <code>start nca fs section dump</code>


* Place nxdumptool rewrite (<code>nxdt_rw_poc.nro</code>) into the switch folder of your SD card, open it through the Homebrew Launcher, and plug the Switch to your computer with a USB cable.
*With nxdumptool open, launch Zadig on your computer, and follow the driver installation instructions below
*# Go to <code>Options</code> and make sure <code>List all devices</code> is checked -- if not, click that option.
*# Using the dropdown list with USB devices, select the name of the NRO you launched on your Switch (e.g. <code>nxdt_rw_poc</code>).
*# Change the <code>Driver</code> dropdown on the right to <code>libusbK</code> (the actual version number doesn't matter).
*# Wait until the installation process finishes. If you did it correctly, Zadig should look like this:

* Open the host app (.exe file extracted from <code>nxdt_host.7z</code>), and click <code>Start Server</code>

'''Dumping DLCs'''
Just like mentioned previously, updates share their filesystem data with the base game, so dumping the RomFS with 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 and update separately.
