Where Does EmuDeck install?

Back to the Top

When you install EmuDeck, EmuDeck prompts for an install location, either the SD Card or the Internal SSD. This install location contains the directory for your ROMs, BIOS, and storage files. Regardless of the location you choose, EmuDeck will install its suite of emulators and tools onto your internal SSD.

How are the various emulators and tools installed or downloaded?

Back to the Top

The emulators and tools that come with EmuDeck come in four primary types: AppImage, Binary, Flatpak, and EXE (through Proton).

Note:

  • Flatpaks can also be updated and managed through Discover.

Why is EmuDeck not downloading?

Back to the Top

Internet issues are an increasingly common issue among Steam Decks, even if your internet works perfectly fine on other devices, or you have the latest and fastest internet. You may notice that EmuDeck isn't installing properly, or is taking a long time time to install. You may notice these same internet issues when you try to browse the internet or download a game and the internet speeds are much slower than you would expect.

You can fix these issues by adjusting your DNS, in System Settings within Desktop Mode, in Configure Network Settings.

Note: If you are noticing unexpected behavior with RetroAchievements causing errant controls or freezing, consider trying the below steps.

Here's How:

  1. Click the bottom left icon in the taskbar (Steam Deck icon), click Settings in the list, open System Settings.
  2. Click Connections on the left.
  3. On the IPv4 tab, change the Method to Automatic (Only Addresses).
  4. In the DNS Servers box, enter 1.1.1.1.
  5. Click the IPv6 tab at the top, change the Method to Disabled.
  6. For good measure, restart your Steam Deck.

Note: If the above steps still do not fix the issue for you, you can try switching to a 2.4 GHz WiFi network if your ISP provides you with one.

What are the hotkeys for the various emulators?

Back to the Top

Refer to the Hotkeys page for a list of hotkeys per system.

If I install EmuDeck, will it clutter my Steam library?

Back to the Top

No! EmuDeck is a "dumb" script that installs a suite of tools and emulators to your Steam Deck. One tool that EmuDeck installs is "Steam ROM Manager", a tool that allows you to add ROMs as non-Steam game shortcuts to your library. You are not required to use Steam ROM Manager.

EmuDeck also installs ES-DE, a front-end that manages all of your ROMs within a single app. You may choose to use either Steam ROM Manager, ES-DE, both, or neither of them. EmuDeck is simply a script, and how you choose to use its installed suite of tools and emulators is up to you.

After you have installed EmuDeck, you can use Steam ROM Manager and select which parsers you would like to use. You can use the ES-DE parser and the Emulators parser to add ES-DE and EmuDeck's installed suite of emulators to your Steam library. Adding emulators to your library allows you to tweak settings directly in Game Mode. Turning on other parsers will add the respective system's ROMs to your library. Learn how to generate and save an app list here: How to Generate and Save an App List.

How do I transfer my initial install of EmuDeck to my SD Card and Vice Versa?

Back to the Top

Preface

When you install EmuDeck, EmuDeck prompts for an install location, either the SD Card or the Internal SSD. This install location contains the directory for your ROMs, BIOS, and storage files. Regardless of the location you choose, EmuDeck will install its suite of emulators and tools onto your internal SSD.

However, you may decide to buy an SD Card and want to move that install location from your internal SSD to your SD card. Or you may want to move all of your files back to the internal SSD.

Here's how:

How do I change the Steam Input Controller Profile?

Back to the Top

Preface

EmuDeck comes with a few Steam Input profiles to make hotkeys easier to use in a few emulators. If an emulator does not have a Steam Input Profile, make sure you're on Gamepad with Joystick Trackpad, otherwise some controls may not work.

EmuDeck comes with Steam Input Profiles for the following emulators:

  • Cemu
  • The Steam Input Profile is necessary to switch screens
  • Citra
  • The Steam Input Profile is necessary to switch screens
  • DuckStation
  • melonDS
  • mGBA
  • PPSSPP
  • RMG

Changing Steam Input Profiles

In Game Mode, single click the game you would like to change the Steam Input Profile for, and click the Controller Icon on the right of the screen. Click the layout (whatever name it is currently set to) at the top, and you will see a drop-down menu. When playing a PSX, 3DS, or Wii U Game, switch to the respective Steam Input Profile.

How to Verify ROMs

Back to the Top

How to Verify a ROM Successfully Transferred

Sometimes, data loss or corruption can occur when you transfer ROMs to your Steam Deck. You can verify that the ROM successfully transferred by checking its MD5 Checksum. An MD5 Checksum is a 32-character hexadecimal number that is computed on a file. If the MD5 checksum on both the file on the Steam Deck and the original PC is an exact match, the file transferred successfully. If they do not match, the file is potentially corrupt. You will need to correct or adjust how you transfer files.

Here's How

On the Steam Deck

  1. Right click the ROM
  2. Click Properties
  4. Click the Checksums tab
  5. Click Calculate to the right of MD5
  6. Wait, it may take a few moments

On the non-Steam Deck PC

How to Verify a ROM is Valid

For one reason or another, your ROM may be corrupt and may not work properly. One way to confirm that you have a valid ROM is by comparing it to the ROM page on redump.org. Redump is an internet community "dedicated to collecting precise and accurate information about every video game ever released". You can validate your ROM by comparing its MD5 Checksum, a 32-character hexadecimal number that is computed on a file, to the MD5 Checksum on redump.org.

Here's How

How to Find your MD5 Checksum

Note: Vampire Night, for the Playstation 2 is being used as an example in the below guide.

  1. Right click the ROM
  2. Click Properties -
  3. Click the Checksums tab
  4. Click Calculate to the right of MD5 - Wait, it may take a few moments - - Note down the MD5 Checksum for the next section

How to Compare your MD5 Checksum to Redump

  1. Open redump.org, and search for your ROM - For example, Vampire Night's page: http://redump.org/disc/13152/
  2. Note down the MD5 Checksum on the redump.org page and compare it to your ROM - Using Vampire Night as an example:
    • MD5 Checksum on the ROM:
    • Redump's MD5 Checksum:
  3. The Vampire Night ISO MD5 Checksum matches to the MD5 Checksum on the redump page, meaning the ROM is valid

Why is my emulator or game muted?

Back to the Top

There is no one known reason why an emulator or ROM (run through an emulator) can accidentally be muted. However, the fix is simple.

Tutorial

  1. In Desktop Mode, open the emulator - Example: If you are playing a PS2 ROM, open PCSX2
  2. Either temporarily turn off the Start in Fullscreen feature or make sure you have a way to use Alt + Tab - You can bind Alt + Tab to a back bumper, plug in a keyboard, or use Anydesk to switch out of the emulator
  3. Launch a game
  4. In the taskbar, press the audio icon, select the Applications tab, in the list, you should see your emulator with a muted speaker icon -
  5. Click the speaker icon to unmute the emulator - Make sure to turn fullscreen back on if you turned it off
  6. This fix applies to any game you launch through that emulator

For systems with multiple emulators, how do I select which emulator to use?

Back to the Top

Steam ROM Manager

These systems will have multiple parsers, each corresponding to a different emulator or RetroArch core. For example: PSX can be played through DuckStation (Standalone), SwanStation, or Beetle PSX. If you prefer to use DuckStation (Standalone) for PSX, enable the Sony PlayStation - DuckStation parser and make sure the SwanStation and Beetle PSX parsers are disabled

ES-DE

These systems will have a set default. However, you can change which emulator or RetroArch core is used:

  1. In ES-DE, press the Start button
  2. Scroll down and select Other Settings
  3. Select Alternative Emulators
  4. Scroll down to the system you would like to configure, press B, and select your preferred emulator

How do I reset an emulator's configurations?

Back to the Top

Sometimes after installing EmuDeck, you may notice an emulator's configurations were not set properly or you tweaked something on accident and you do not remember the default settings.

You may reset an emulator's configurations in the Manage Emulators page.

Tutorial

  1. Open EmuDeck on your desktop.
  2. Click the Manage Emulators button.
  3. Select which emulator configurations you would like to reset in the drop-down menu.
  4. Click Reset configuration, wait a moment.
  5. Using PCSX2 as an example:
  6. Your selected emulator has been reset.

How do I navigate to my SD Card through an emulator's menu?

Back to the Top

For some emulators, you may need to navigate to your SD Card to install updates/DLC or locate a file of some sort for the emulator. On Linux, your SD card is a file path, so navigating there through the menu will look different.

Using Yuzu as a Reference:

  1. Open Yuzu.
  2. Click Files, Install files to NAND.
  3. Click Computer on the left.
  4. Your SD Card path is /run/media/mmcblk0p1.
  5. mmcblk0p1 is the default name of the SD Card when formatted by the Steam Deck.
  6. You will now see your Emulation folder and you can proceed to locate your files.

For some emulators, you may need to click Other Locations first before seeing Computer.

Why are my emulators stuttering? How do I improve emulator performance?

Back to the Top

There may be a number of reasons for this, but your first debugging tool should be to ensure that both the frame limiter and the refresh rate are off. Consider turning off half rate shading if you had it previously on. Half rate shading may cause visual glitches as well.

To find these options, press the QAM ("..." button), press the battery icon, press advanced view.

Note: It's a good idea to use per game profiles if you intend on changing any of these settings.

Does EmuDeck have a game compatibility list?

Citra and Yuzu FAQ

Back to the Top

If I already have Citra or Yuzu installed on my system, will this EmuDeck update remove either emulator?

No, existing installs will not be touched.

I don't have Citra or Yuzu, how do I download them?

Since the original GitHub pages for both Citra and Yuzu have been taken down, there is no longer an official source for either emulator.

Forked repositories ("copies" in other words) of these repositories have been taken down by Nintendo (primarily forks/"copies" of Yuzu).

Due to take-down concerns, distribution of Citra and Yuzu is a sensitive subject and this wiki nor the EmuDeck Discord will cover how to locate copies of either Citra and Yuzu.

If you can locate a copy of Citra or Yuzu, you may proceed with the rest of the FAQ to learn how to properly use these copies to get the latest EmuDeck configurations.

Can I still use Citra or Yuzu through Steam ROM Manager and ES-DE?

For Steam ROM Manager, yes, a parser is included for both emulators. If you are missing these parsers, reset Steam ROM Manager's configurations on the Manage Emulators page in the EmuDeck application.

For ES-DE, Citra will continue to be supported. Yuzu support will be removed in the next update. This means that if you use ES-DE as a front-end for your ROMs, you will no longer be able to use Yuzu to launch Nintendo Switch games.

However, EmuDeck has pushed a hotfix to add back support for Yuzu. In order to get this hotfix, open the EmuDeck application and say yes to the prompt. If you say no or miss this prompt, you may also apply this hotfix at any time by resetting ES-DE or Yuzu on the "Manage Emulators" page in the EmuDeck application.

Why does ES-DE default to Ryujinx?

Since EmuDeck can no longer install Yuzu for new users, Ryujinx was set as the default emulator in ES-DE. However, swapping back to Yuzu is fairly easy. Do note, you will need the EmuDeck hotfix in order to continue using Yuzu in ES-DE. If you missed this hotfix, you may apply it at any time by resetting Yuzu on the "Manage Emulators" page in the EmuDeck application.

To swap back to Yuzu:

  1. In ES-DE, press the Start button
  2. Scroll down and select Other Settings
  3. Select Alternative Emulators
  4. Scroll down to switch, select Yuzu (Standalone)

How do I get the latest EmuDeck launchers and configurations on Linux/SteamOS?

Place citra-qt.AppImage and yuzu.AppImage directly in $HOME/Applications (/home/deck/Applications on a Steam Deck). No subfolders. The names are case sensitive.

After you have placed the AppImages in the appropriate place, you will see a "Reset configuration" button on each emulator page on the Manage Emulators page in the EmuDeck application. Click "Reset configuration" to get the latest launcher and configurations.

The latest configurations will work with the new Steam Input profiles included in EmuDeck 2.2. See Emulator Frontends Button Combinations Profile and Emulator Frontends Radial Menu Profile for more information.

File Extensions

Yuzu on Linux was distributed as both an AppImage and a Flatpak. With Yuzu shutting down, the Flatpak was also removed from Discover. If you are still using Yuzu, you will likely be using an AppImage. AppImages have a .AppImage file extension. Files that have a .exe file extension are for Windows only. You can run these through Wine/Proton, but there is little to no reason to since Yuzu also had a widely available Linux distribution.

How do I get the latest EmuDeck launchers and configurations on Windows?

The files for both emulators should be located in %USERPROFILE%\EmuDeck\EmulationStation-DE\emulators\citra and %USERPROFILE%\EmuDeck\EmulationStation-DE\emulators\yuzu\yuzu-windows-msvc respectively.

After you have placed the emulator files in the appropriate place, you will see a "Reset configuration" button on each emulator page on the Manage Emulators page in the EmuDeck application. Click "Reset configuration" to get the latest launcher and configurations.

File Extensions

Windows applications, including Yuzu, typically have a .exe file extension. If you have a file with a .AppImage file extension, you have the incorrect file. Files that have a .AppImage file extension are for Linux only. If you are playing on Windows, you must locate a file with a .exe file extension.

Why does the BIOS checker say I have missing firmware?

Now that EmuDeck installs Ryujinx by default and can no longer install Yuzu, the BIOS checker only checks for the presence of both Ryujinx keys and firmware.

For Ryujinx, both keys and firmware are required. If you do not have Ryujinx keys and firmware, the BIOS checker will say these are missing.

If you only have Yuzu keys (since the BIOS checker only checks for Ryujinx) and do not have Ryujinx configured, the BIOS checker will say these are missing.

However, the BIOS checker does not correlate to the validity of the keys in Yuzu. If you have the keys in place and you can confirm that these are valid, then Yuzu will work just fine.
