Getting Started with Yuzu

Back to the Top

In order to play Nintendo Switch games on Yuzu, you will need a prod.keys file and title.keys to decrypt your ROMs. You will need to continue to keep your prod.keys and title.keys up to date as new Nintendo Switch firmware releases.

If you play a Nintendo Switch game with Miis (for example - Mario Kart 8 Deluxe), you will need firmware files.

Read Yuzu's Quick Start guide to learn how to dump Nintendo Switch keys, firmware, and ROMs: https://yuzu-emu.org/help/quickstart/.

Place your ROMs in Emulation/roms/switch. Place your prod.keys file in Emulation/bios/yuzu/keys. Place your firmware files in Emulation/bios/yuzu/firmware.

Read the Configuration section to learn more about Yuzu and its folder locations.

To launch your ROMs in game mode, use Steam ROM Manager and use one of the following parsers to play your Nintendo Switch ROMs:

  • EmulationStation-DE
  • Nintendo Switch - Yuzu
  • Emulators

How to Manage DLC and Updates

Back to the Top

Preface: Do not keep your DLC or update files in the Emulation/roms/switch folder. Steam ROM Manager will parse your updates and DLC and create broken shortcuts. After installing your DLC or updates, you can discard them or save them for Ryujinx.

Ryujinx expects your DLC and update files to stay permanently in a folder, either in a folder of your choice, or in Emulation/storage/ryujinx/patchesAndDlc. For further detail, read: https://github.com/dragoonDorise/EmuDeck/wiki/ryujinx#how-to-manage-dlc-and-updates.

DLC and Updates are installed directly through the Yuzu menu.

Quick Tutorial

  1. In Desktop Mode, open Yuzu
  2. Click File
  3. Click Install Files to NAND..
  4. (Optional) If your DLC or update files are on your SD Card, your path is: /run/media/.... To navigate here, click Computer on the left, open the / folder, open the run folder, then the media folder, and follow the path to the files on your SD Card.
  5. Locate your DLC or update files in your directory
  6. Your DLC or update files are now installed

Yuzu Common Issues

Special Characters

Back to the Top

Files with special characters in the ROM name will not launch from Steam. Rename your ROMs and remove the special character.

Known Cases:

  • é in Pokémon
  • ' in The Legend of Zelda: Link's Awakening

If you used Steam ROM Manager previously, re-run Steam ROM Manager after renaming your ROMs.

Combined XCI Files

Combined Nintendo Switch games can be unreliable. These combined games will still work if you open them through Yuzu directly.

However, using combined games may cause issues if you are using a shortcut created by Steam ROM Manager or running the game through EmulationStation-DE.

It is recommended you do not use combined games if you want to use shortcuts created by Steam ROM Manager or run your games through EmulationStation-DE.

Why is Mario Kart 8 stuck on the Mii selection screen?

Back to the Top

Dump and use your firmware and keys from your console following Yuzu's quickstart guide.

The firmware must contain Mii data. Without it, the game will get stuck on the Mii selection screen.

If the game is stuck on a Mii selection screen, that means your firmware does not contain Mii data. You will need to re-dump your firmware.

Reference Image:

After you dump your firmware with Mii data, place it in Emulation/bios/yuzu/firmware.

Once you have dumped your firmware with the proper Mii data and place it in the correct folder, you will be able to proceed through the Mii selection menu.

Why is New Super Mario Bros U Deluxe stuck on a black screen?

Back to the Top

Dump and use your firmware and keys from your console following Yuzu's quickstart guide.

The firmware must contain Mii data. Without it, the game will launch into a black screen.

If the game is stuck on a black screen, that means your firmware does not contain Mii data. You will need to re-dump your firmware.

After you dump your firmware with Mii data, place it in Emulation/bios/yuzu/firmware.

Once you have dumped your firmware with the proper Mii data and place it in the correct folder, the game will proceed and you will be able to play.
