Yuzu Reader How To Use

Please use the general how-to guide, which includes instructions on dumping the necessary files from your switch to have yuzu derive all of your keys,

For all: If you try to run recent games and you haven’t done the key derivation process recently, you may need to redump and rerun it as newer games use newer keys only available on newer firmwares. Getting an incorrect key means you might have a bad dump of your switch’s files. Try again and if it persists, contact the discord. If you are missing the titlekey or an update won’t load, sometimes updates change the titlekey between versions – either way redump and if that doesn’t work contact the discord/devs.

Other Common Errors

Corruption Errors - All of these errors are indicative of a bad/corrupt dump. If there are no special instructions, try redumping. Should the error persist contact the devs/discord for help.

Less Common General Errors - You should not expect to see these unless you are doing more than just playing games

Less Common Key Errors - Below errors should not be obtained if using the normal key derivation process (which is highly encouraged for newcomers), but if you are not using it these errors will make sense to you.

Internal Errors - Should never be seen ever. Report to the devs immediately.

Downloading and Installing yuzu

Hardware Requirements

• Our recommended specifications don’t guarantee perfect performance in most games, but rather strive to provide a cost effective recommendation while still considering performance.

• Most games are playable on older Nvidia GPUs from the Fermi family (400 series) or later, but at least Pascal (1000 series) is strongly recommended.

• CPUs lacking the FMA instruction set will produce very poor results. Intel Core gen 3 series or older, AMD phenom II or older and all Pentium/Celeron/Atom CPUs will not produce optimal results.

• Mobile CPUs will not reach the same performance as their desktop counterparts due to thermal, power, and technical limitations.

• GPUs must support OpenGL 4.6 & OpenGL Compatibility profile, or Vulkan 1.1 (or higher).
  To find out if your GPU meets these requirements, visit https://opengl.gpuinfo.org or https://vulkan.gpuinfo.org/ and check your GPU details.

yuzu Quickstart Guide

To start playing commercial 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.

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 TegraRcmGUI_v2.6_Installer.msi
• Hekate – Download hekate_ctcaer_X.X.X_Nyx_X.X.X.zip
• Atmosphere – Download both atmosphere-X.X.X-master-XXXXXXXX+hbl-X.X.X+hbmenu-X.X.X.zip and fusee-primary.bin
• Lockpick_RCM – Download Lockpick_RCM.bin
• nxdumptool – Download nxdumptool.nro
• nxDumpMerger – Download nxDumpMerger_Windows.zip
• TegraExplorer – Download TegraExplorer.bin
• 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:

Preparing the microSD Card

1. We will now prepare the microSD card.
   • 1a. Extract the contents inside the atmosphere-X.X.X-master-XXXXXXXX+hbl-X.X.X+hbmenu-X.X.X.zip and hekate_ctcaer_X.X.X_Nyx_X.X.X.zip files into the root of your microSD card. Just drag and drop the contents, do not create any new folders.
   • 1b. Rename the hekate_ctcaer_X.X.X.bin file to reboot_payload.bin and move it into the atmosphere folder. Replace the file when prompted.
   • 1c. Place the fusee-primary.bin, Lockpick_RCM.bin and TegraExplorer.bin files into the payloads folder, which is inside the bootloader folder in your microSD card.
   • 1d. Create a folder named nxdumptool within the switch folder of your SD card and place the nxdumptool.nro file inside it.
   • 1e. Once done, eject the microSD card and insert it into your Nintendo Switch.

Booting into RCM

1. We will now boot your Nintendo Switch into RCM mode
   • 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. If you see the Nintendo Switch icon in the lower left corner flash green and state RCM O.K., your switch has successfully entered RCM mode.

Booting into Hekate

1. We will now boot your Nintendo Switch (already in RCM mode) into Hekate, a custom bootloader.
   • 3a. Extract the hekate_ctcaer_X.X.X.bin file from the hekate_ctcaer_X.X.X_Nyx_X.X.X.zip file you downloaded from the prerequisites to any accessible directory on your computer.
   • 3b. Run TegraRcmGUI. In the Payload tab of TegraRcmGUI, click on the folder icon and navigate to the hekate_ctcaer_X.X.X.bin file you extracted earlier.
   • 3c. Click on Inject Payload and your Switch will boot into the Hekate menu.
     

Mounting the microSD card to your computer in Hekate

NOTE: These steps will be used in other sections below. Do not follow this section yet if you are booted into Hekate for the first time. Skip to the next section for now.

   • 7e. Tap on 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.
