yuzu Quickstart Guide

To start playing games, yuzu needs a couple of system files and folders from your switch in order to play them properly. To check if your Switch is hackable, visit https://damota.me/ssnc/checker and test your Switch’s serial number.

- If your Switch is patched, you will be unable to complete the following steps.
- The Switch v2 (Mariko) and the Switch Lite are both patched and you will not be able to complete the following steps.

This guide will help you copy all your system files, games, updates, and DLC from your switch to your computer and organize them in a format yuzu understands. This process should take about 60 to 90 minutes.

IMPORTANT:
Make sure to place your Nintendo Switch into Airplane Mode before starting this guide.

System Settings -> Airplane Mode -> Airplane Mode "ON"

Prerequisites

  • A Nintendo Switch vulnerable to the fusée gelée RCM exploit – Visit https://damota.me/ssnc/checker and test your Switch’s serial number
  • An SD card with at least 30 GB of free space (an almost empty 32GB card will work)
  • A USB-C to USB-A or USB-C to USB-C Cable to connect your Switch to your computer
  • TegraRcmGUI – Download the TegraRcmGUI installer
  • Hekate – Download the hekate zip file
  • Atmosphere – Download both the atmosphere zip file and fusee-primary.bin
  • Lockpick_RCM – Download Lockpick_RCM.bin
  • nxdumptool – Download nxdumptool.nro
  • Copy Script
  • HacDiskMount
  • microSD Card Reader – If your computer has one built-in, you can use that
  • RCM Jig <– We highly recommend one like this, but you could use any of the methods outlined here

%YUZU_DIR% is the home directory for yuzu on your computer:

- For Windows, this is '%APPDATA%\yuzu' or 'C:\Users\{username}\AppData\Roaming\yuzu'
- For Linux, this is '~/.local/share/yuzu'

Preparing the microSD Card

  1. We will now prepare the microSD card.
    • 1a. Extract the contents of the atmosphere and hekate zip files into the root of your SD card.
    • 1b. Place the fusee-primary.bin and Lockpick_RCM.bin files into the bootloader/payloads folder of the SD card.
    • 1c. Create a folder named nxdumptool within the switch folder of your SD card and place the nxdumptool.nro file inside it.
    • 1d. Once done, eject the SD card and place it into your Nintendo Switch.
Your SD card should look like this.

Your SD card should look like this.

Dumping BIS Keys

  1. We will now dump your BIS (Built-In Storage) keys for use in later decryption.
    • 2a. Run the TegraRcmGUI installer you downloaded from the prerequisites, and after installation, start the program.
    • 2b. In the Settings tab, click on Install Driver which will install the drivers necessary for your computer to interface with your Nintendo Switch.
    • 2c. After the drivers have been installed, plug your Nintendo Switch into your computer.
    • 2d. Power off your Switch while it is still connected to your computer.
    • 2e. Insert your RCM jig into the right joy-con slot, make sure it is seated securely at the base, and then press VOL+ and Power buttons at the same time. Nothing should happen on your Switch; if the switch starts to turn on normally, go back to the beginning of step 2d and try again.
    • 2f. In the program TegraRcmGUI you should see the Nintendo Switch icon in the lower left corner flash green and state RCM O.K.
    • 2g. In the Tools tab of TegraRcmGUI, click on biskeydump (by rajkosto).
    • 2h. Your Switch will briefly flash with a blue QR code (you may or may not see this) and your computer will prompt you to save a text document titled BIS_keys.txt. Navigate to %YUZU_DIR%/keys and save the file as console.keys. Open the file to make sure you have the following key entries.
      • HWI
      • SBK
      • TSEC KEY
      • BIS KEY 0 (crypt)
      • BIS KEY 0 (tweak)
      • BIS KEY 1 (crypt)
      • BIS KEY 1 (tweak)
      • BIS KEY 2 (crypt)
      • BIS KEY 2 (tweak)
      • BIS KEY 3 (crypt)
      • BIS KEY 3 (tweak)


Dumping Prod.keys and Title.keys

  1. We will now dump your prod.keys and title.keys for decryption of your game files.
    • 3a. Boot your Nintendo Switch into RCM mode (steps 2d to 2f) and make sure it is connected to your computer.
    • 3b. Extract the hekate.bin file from the hekate zip file you downloaded from the prerequisites.
    • 3c. Run TegraRcmGUI. In the Payload tab of TegraRcmGUI, click on the folder icon and navigate to the hekate.bin file you extracted earlier.
    • 3d. Click on Inject Payload and your Switch will boot into the Hekate menu.
    • 3e. When it has successfully booted into the Hekate menu, tap on Payloads. This will show a list of payloads.
    • 3f. Tap on Lockpick_RCM.bin in the list of payloads.
    • 3g. After Lockpick_RCM has successfully booted, press the power button to select Dump from SysNAND.
    • 3h. It will automatically boot to sept and start deriving the keys. Wait for it to finish deriving the keys.
    • 3i. After Lockpick_RCM has finished deriving the keys, please make note of the location of the key files. Default is: sd:/switch/prod.keys and sd:/switch/title.keys.
    • 3j. Press any key to return to the menu, then navigate with the VOL+/VOL- buttons to highlight and select Power Off by pressing the power button.
    • 3h. Once your Switch is powered off, remove the SD card.
    • 3i. Insert your SD card into your computer and copy both prod.keys and title.keys to the %YUZU_DIR%/keys directory.

Backing up System Files

  1. We will now boot Hekate to dump your system files:
    • 4a. Boot your Nintendo Switch into RCM mode (steps 2d to 2f) and make sure it is connected to your computer.
    • 4b. Run TegraRcmGUI. In the Payload tab of TegraRcmGUI, click on the folder icon and navigate to the hekate.bin file you extracted earlier. (step 3b)
    • 4c. Click on Inject Payload and your Switch will boot into the Hekate menu.
    • 4d. Select Tools, the wrench icon at the top of the screen, and select Backup eMMC. Underneath the Full section, tap on eMMC BOOT0 & BOOT1. This may take a few seconds to load. After it is finished filling the progress bar it should say Finished and verified!. Beneath Filepath: you will see the location of the dump.
    • 4e. Click Close and select eMMC RAW GPP. This should take some time as the Switch’s rawnand.bin is quite large. If the progress bar appears to go backwards at some points or turn green, do not worry as this is Hekate verifying the data. This should take between 15-45 minutes depending on the quality/speed of your SD card and the default verification setting. Please keep note of the location the output file is placed.
    • 4f. Power off your switch to avoid damage to your SD card by selecting Back and then selecting Power Off and then eject your SD card. Insert your SD card into your computer and use your file explorer to open the contents. Place the yuzu_copy.bat file you downloaded earlier into the root of your SD card. Double-click it to start combining your rawnand.bin if it was dumped into sections i.e. rawnand.bin.00. If your rawnand.bin dumped as one ~30gb file, then proceed with the guide.
    • 4g. If you needed to dump the rawnand.bin into sections due to lack of space on your sd card, transfer the files that did dump to a new folder on your desktop, and then resume the backup of your eMMC RAW GPP. After you have obtained all of the rawnand.bin files, add them to the same folder as before, place the yuzu_copy.bat file you downloaded earlier into that same folder and double-click to run. After they are combined, please proceed with the guide.

Moving SYSTEM and USER to the yuzu directory

  1. We will now extract the necessary directories from your rawnand.bin for yuzu to read your system files.
    • 5a. Open HacDiskMount as Administrator (Right-click and select Run As Administrator) and go to File > Open file and select your rawnand.bin.
    • 5b. Double-click on the row marked PRODINFO. Under the dump to file area, click browse and pick somewhere easy to get to, like your Desktop. Dump the file as PRODINFO.bin. Click start and wait for it to complete. Then close the window. (NOTE: There is no need to enter any keys in the boxes at the top of the dialog at this moment.)
    • 5c. Select the row named BCPKG2-1-Normal-Main. Under the dump to file area, click browse and pick somewhere easy to get to, like your Desktop. Dump the file as BCPKG2-1-Normal-Main.bin. Click start and wait for it to complete. Again, no keys are necessary at this point. After it finishes, close the window.
    • 5d. Copy the PRODINFO.bin and BCPKG2-1-Normal-Main.bin files to the %YUZU_DIR%/sysdata directory.
    • 5e. Double-click on the row named SYSTEM. In the keys box, enter the bis_key2_crypt key in the crypt box and the bis_key2_tweak key in the tweak box and click test. If the text is red, double check your keys. If the text is blue, click on Install and wait until it says Driver (ver XXXXX) installed, Service is running where XXXXX is anything, then select Y: in the dropdown and click Mount. The application may become unresponsive for a moment. Press Windows-R and type Y: into the box and click OK and there will be a couple of folders with some named Contents and save. Copy all of these into %YUZU_DIR%/nand/system. After this is done, click Unmount and close the window.
    • 5f. Double-click on the row named USER. Enter the same key and click Mount (the tool may become unresponsive again). Once this mounts, open the new drive and copy the Contents and save folders to %YUZU_DIR%/nand/user. After this, click Unmount and close the window and then the program.
    • 5g. If you have games or game data stored on your SD card, copy the Nintendo folder of your SD card into %YUZU_DIR%/sdmc.
