Emulator configurator for Steam Deck

EmuDeck

EmuDeck is a collection of scripts that allows you to autoconfigure your Steam Deck or any other Linux Distro, it creates your roms directory structure and downloads all of the needed Emulators for you along with the best configurations for each of them. EmuDeck works great with Steam Rom Manager or with EmulationStation DE

How to use EmuDeck?

We recomend you take a look at our extensive Wiki, you'll find guides, videos and all sorts of content about the project:

EmuDeck Wiki

Developers, developers, developers.

If you wanna help us improve EmuDeck we are open to accept your PR! Just keep in mind this simple guide:

• Think that EmuDeck is for everybody, tech savvy and is specially directed to regular users that are new to Emulation, so everything has to be properly explained.
• Things using sudo are a big no no, there are exceptions but always try to find a way of prevent using sudo.
• Every Emulator needs to have a SRM profile and follow the AmberElec hotkey mapping.
• Always do your PR to the dev branch.

Submitting a PR Request for a Steam ROM Manager Parser

If you would like to submit a PR request for a Steam ROM Manager parser, use the following format:

The Basics

• Spell out console names - no acronyms
  • For example, PSP should be spelled out as PlayStation Portable
• Respect original capitalization and spacing
  • A few examples:
    • RetroArch uses a capital R and capital A
    • The Nintendo Game Boy uses a capital N, G, and B with spaces between each word
    • The PlayStation Portable uses a capital P and S in PlayStation as do the other PlayStation handhelds and consoles

Parser Structure

• configTitle:
  • COMPANYNAME SYSTEMNAME - EMULATORNAME RETROARCHCORENAME
    • If the standalone emulator name is identical to the RetroArch core name, add (Standalone) behind the EMULATORNAME
  • A few examples:
    • Config Title: "configTitle": "Amiga - RetroArch PUAE",
    • Config Title: "configTitle": "Nintendo Game Boy Color - mGBA (Standalone)",
    • Config Title: "configTitle": "Sony PlayStation 2 - PCSX2",
• steamCategory:
  • Note: Non-Default Parsers refer to when a system has multiple emulation choices (through alternative emulators or RetroArch cores). Only one of these parsers is enabled by default and any alternative choices are disabled by default.
  • Default Parsers:
    • COMPANYNAME CONSOLENAME
  • Non-Default Parsers:
    • Standalone: COMPANYNAME CONSOLENAME - EMULATORNAME
    • RetroArch Core: COMPANYNAME CONSOLENAME - RETROARCHCORENAME
      • If the RetroArch core's name is identical to the Standalone emulator name, add RetroArch in front of the RETROARCHCORENAME
      • If the standalone emulator name is identical to the RetroArch core name, add (Standalone) behind the EMULATORNAME
  • A few examples:
    • Default Parsers:
      • Mupen64Plus Next (RetroArch core for Nintendo 64)
        • Steam Category Name: "steamCategory": ""${Nintendo 64}",
      • DuckStation (PSX Emulator)
        • Steam Category Name: "steamCategory": "${Sony PlayStation}",
    • Non-Default Parsers:
      • Rosalie's Mupen GUI (N64 Emulator)
        • Steam Category Name: "steamCategory": "${Nintendo 64 - Rosalie's Mupen GUI}",
      • Beetle PSX HW (RetroArch core for PSX)
        • Steam Category Name: "steamCategory": "${Sony PlayStation - Beetle PSX HW}",

Parser Filename

companyname_systemname-emulatorname-retroarchcore.json

If it is a RetroArch core, replace emulatorname with ra.

• A few examples:
  • nintendo_wii-dolphin.json
  • nintendo_64-rmg.json
  • nintendo_gba-ra-mgba.json
  • sega_saturn-ra-mednafen.json

emudeck's Issues

Controls not recognized on GameCube games

When I launch GameCube games from EmulationStation, the controls works just fine on my GameCube games, but when I launch them directly from the shortcut in Steam, they doesn't work. When I load the games in EmulationStation I can see a little box appearing telling me that the virtual controller has been set or something like that, but not on the shortcut version. Is there a way to fix this, or maybe I'm doing something wrong?

P.S. I really like EmuDeck, I think it's amazing what you've done!

Atari Lynx fix

Dolphin Config

Paths in the dolphin config are weird.

EmuDeck/configs/org.DolphinEmu.dolphin-emu/config/dolphin-emu/Dolphin.ini

Line 35 in dc33a0c

ISOPath0 = /run/user/1000/doc/77fd26b2/GameCube

I tested manually changing the file to the correct paths and it was fine, but if i updated them in the front end they look like that.

Why format sd card

The instructions say in the first step to format your sd card but fails to explain why a sd card is needed.

AT-SPI: Could not obtain desktop path or name

Currently encountering this issue after deleting the Emulation folder on my BTRFS formatted SD Card and running the .desktop file again to rerun the Emudeck installation script.

After running the .desktop file, it asks if I want to install my roms on either the Internal Storage or SD Card. Selecting SD Card will lead to an error:

EmuDeck ERROR

An error has occurred.

and the Konsole will close with the log below:

Whenever duplicate preexisting symlinks occur, symlinking in install.sh creates recursive copies in their target folders

@dragoonDorise, while working on the Launchbox folders solution, I am noticing a bug with the current symlink creation scheme for EmuDeck. The problem is a symlink will be created recursively inside of the target folder if the symlink already exists. For example, if the megadrive symlink already exists, the command in the install script will create that symlink inside of the megadrive symlinked folder. The fix to this is creating a conditional if statement check to see if the symlink already exists.

That would mean changing this:
cd $(echo $romsPath | tr -d '\r') ln -s segacd megacd &>> ~/emudeck/emudeck.log (...)
To this:
cd $(echo $romsPath | tr -d '\r') if [ ! -d "megacd" ]; then ln -s "segacd" megacd fi (...)

This impacts all symlinks in the bash script install.sh in the same way. You need this format of check to test for folder existence first or symlinking will recurse with subsequent runtimes. I have to delete a ton of nested symlinks because of this anomaly whenever rerunning the script.

[feature request] Xenia support

Xenia is a Xbox 360 emulator on windows at the moment and is being ported to Linux. Xenia is able to do a range amount of games. Currently only way that the developers on the discord suggested to run Xenia at the moment is to use wine/proton and seems like some people get good results on Linux. There haven't really been much testing that I saw on steam deck on Linux side but some have been testing on windows 10 dual booted which seemed to run alright. What would be ideal is to have Linux port used on emudeck but other option is using wine/proton as a compatibility layer.

PCSX2 always crash when trying to boot a game

Hi!

I've been trying to boot any ps2 game and I always get the same result; pcsx2 just closes.

I've tried with games in US and EU region, with .iso and .chd and it's always the same.

The only strange thing I noticed was that I installed it using the internal storage but when it tried to search for bios it was trying to search on run/media/mmcblkppq/Emulation/bios, I just switched it to home/deck/Emulation/bios.

For now it's the only emulator I've been having trouble with. I've tried SNES/N64/PS3/3DS/Switch and everything ran perfectly.

The log doesn't really says anything helpful but here it is in case that you need it:

Please give us an option for which emulators to install

I don't want to install all of them. I pretty much only care for Nintendo games.

RetroArch Steam support

It would be great to support the Steam version of RetroArch (cloud save, ...)

Should be doable with just changing paths to the steam version (maybe user-selectable?).

Installing cores might be tricky, IDK if that's possible outside of steam.
Still would be great to support it, even if cores have to be installed manually.

Flatpak Permissions Automation

We should automate the setting for rpcs3.

Especially for SD card installs, we should add the sd card path to the flatpak permissions.

https://docs.flatpak.org/en/latest/sandbox-permissions.html

I haven't actually read through how to do this yet, still in idea phase.

I'd want to prompt the user with a question about it, rather than adusting their permissions without them knowing.

Retroarch config

Reports that retroarch config doesn't get updated during the script when internal is selected. Test in dev!

Issues loading PS3 Games

Users have reported the PS3 games don't load on STEAM UI

Revamp controls

I would like to create more / revamp the controller templates.

Moskeeto, in our discord, has come up with a really nice left touchpad quick menu setup. I'd like to propose we build this for each emulator for emulation hotkeys.

I'd also like to standarize the right touchpad as mouse instead of joystick.

[Suggestion] Thinking of ideas to add specific controller mappings

First of all thanks for this script and setup!

I was wondering if it's possible to use your script to add controller mappings on the deck to specific emulators maybe?

For example, Yuzu doesn't quit properly if a game is launched via Steam command line in full screen and the most common fix is mapping CTRL+Q on a button to force close it. But since mappings on steam are individual by the game in the library, I was wondering if those kinds of extras could be done as part of the script?
something like, IF YUZU THEN ADD CTRL+Q TO R5 BUTTON

3ds and n3ds folders

Symlink one to the other so it works for both retroarch and emulationstation-de.

PCSX2 Config

Reports that when selecting internal, it doesn't update the path in the config from the external location. test in dev, see if it fixes it with the other sed fixes.

Issues installing with more than 1 SD Cards

Move emulationstation config directory to SD card

When configuring EmuDeck for the SD card, it should also point EmulationStation's config directory to the SD card. This is because if you decide to scrape game media using ES, your home directory can get quite large, filling your internal storage rather quickly. My workaround for this was to move ~/.emulationstation to /run/media/mmcblk0p1/Emulation/es_config and then create a symbolic link between the two locations. This allows me to download as much metadata as I'd like on my 64GB SteamDeck 🙂

Undo what's done by the script

I wasn't satisfied with EmuDeck and I couldn't find any way to complete undo what was done by the script. This goes in particular for the controller templates that get added by it.

For now I just deleted the folder, but I still need to find out how to delete the templates. Anyhow it would be greatly appreciated to add instructions (or a script) on how to get rid EmuDeck if you don't want it anymore.

Yuzu controls don't work

User reported

Yuzu directory config errors after recent SteamOS Update.

My deck was caught in a bootloop from trying to update via the Desktop, after re-imaging was performed I reinstalled Emudeck using the new Easy mode. Upon opening Yuzu I found that it was pointing to the wrong game directory folder and the one configured didn't exist, as well as the Keys folder link not having been created in the deck/emulation/Bios/Yuzu directory.

Support for ROMs on SD & Internal storage

There should be no need to specify if roms and BIOSes should "live" on the internal storage or on the SD card. Emulators like Dolphin already support adding multiple paths to the config (so for Dolphin the scripts could just add both the SD card path and the internal storage path to the config), and if there's emulators that don't, maybe something like OverlayFS could be added to EmuDeck?

That'd make it so that both files from /home/deck/Emulation and from /run/media/*/Emulation would be visible under one standard path like /opt/Emulation, and it would be possible to have some ROMs on internal storage and others on the SD card, and the emulators would always see all of them, as if they were all on the same storage.

Unable to save config: retroarch.cfg

Versions
EmuDeck: 0.14.1, 015.1
RetroArch: 1.10.2
SteamOS: 20220227.3

Issue Description
After using the EmuDeck script, I lose the ability to save to the retroarch.cfg config file. After loading a core and rom, I get the following error:

Failed saving config to
"/home/deck/.var/app/org.libretro.RetroArch/config/retroarch/retroarch.cfg"

Troubleshooting Steps

• Issue is replicatable. If you wipe the Steam Deck to factory-default and install via EmuDeck script, you will be unable to save the local config.
• Enabled all file permissions in Flatseal
• Enabled write permissions for others for retroarch.cfg
• Restoring the Deck to factory-default and installing RetroArch first allows you to save the config. After installing EmuDeck, I then lose the ability to save.

Workaround

• Install EmuDeck
• Delete the RetroArch Flatpak
• Delete the "/home/deck/.var/app/org.libretro.RetroArch/" folder
• Install RetroArch Flatpak
• Overwrite the retroarch.cfg file with the EmuDeck version
• Manually install cores

Bezels / Overlays not showing

Hey I just tried Emudeck, great work, but the bezels don't show up for me I even reinstalled everything, chose expert mode and made sure to select the overlays. Didn't work. I'm using Emulation Station and didn't import any games with steam rom manager. I've tested SNES, N64 and NES. No bezels.

I'm actually pretty familiar on retroarch on windows, so I don't think I'm missing something here. Usually when auto loading overlays, overlays should be set to on in the retroarch main config and opacity should be set to 100. Both is not so. Also there should be a core config or content directory in the retroarch config folder for snes9x, but there is none. I guess something goes wrong during installation.

Also the aspect ratio of the snes core is wrong it's stretched, not 4:3. That is also because the custom config files is missing.

scripts improvements

• Switch shebang to bash, it seems to be a bash script and you are even executing it in bash DONE
• remove the 999999 sleeps and swap them for a simple read, it'll hang until enter is pressed instead of "unexitable" sleep DONE
• since you seem to be using versioning - why not add the version to the script itself? DONE
• make your editor to kill trailing newlines, there's a bunch of tabs strewn around the files at ends of lines DONE
• make your editor show you spaces/tabs in the first place, sometimes there's a mix of 'tab-space-tab' DONE
• make your editor run shellcheck on the file - it'll show you problems like unused variables (for example raCorePath) DONE
• use a different delimiter for sed other than / when dealing with file paths, it'll allow you not to have to escape a bazillion slashes DONE
• why make the user download and extract cemu instead of doing it in the script itself? DONE
• probably should say 'BIOSs'

Add Option to not overwrite / reset steam rom manager configuration

Hi,

I've made many changes to the steam rom manager config file (using SRM itselve). But there does not seem to be an option to keep my config changes, even when choosing no at installing SRM (as i had it downloaded manually) it will still try to configure the Steam rom manager overwriting / resetting any changes i / we did. Maybe also ask a question if we want steam rom manager config reconfigured / rewritten so we can keep our customn configs but still update all other parts using emudeck script

PS3 not working at all

Invalid file or folder. I think it's related to flatpak or something like that. If I install disc from same folder as would steam rom manager and create shortcut from that it will have completely different path: Exec="/app/bin/rpcs3" --no-gui "/run/user/1000/doc/e74b382/Persona 5/PS3_GAME"

Open Emulator Menus from inside SteamUI

Kriss Hietala — Today at 10:58 PM
@dragoonDorise Is it possible for emudeck to configure hotkeys/shortcuts for quick menu ? Like retroarch L3+r3?

[Suggestion] Bios scanning

Whilst including bios files for various systems may not be possible. And automatically downloading them from an external source, will be unreliable and also questionable.

EmuDeck could scan for files in a user provided directory (maybe default to the user directory) and automatically copy them to the needed directory and rename them as needed.

This would make things easier for less technically savvy users. (A similar feature using rom fingerprinting systems may also be possible)

Scanning should use known hashes to match correct bioses.

Suggested implementation would go something like.

• Prompt: Do you already have any system bioses you wish to use? (y/N) ...
• If yes. Prompt: Where are they located? (~) ...
• Scan the directory hashing files to find bioses.
• Copy/rename bioses that match appropriate hashes to their appropriate folder wherever user specified (sdcard or not)

Known hashes can be found on various wiki's like https://emulation.gametechwiki.com/index.php/File_Hashes (some like for yuzu or so may need sourcing elsewhere)

Now fails on BTRFS (non-ext4) formatted cards

Complains a BTRFS formatted SD card isn't ext4 even though BTRFS works just fine and refuses to continue.

Launching 3d0 roms from emulation station gives an error that 4d0_libretro.so is missing

Rumble does not work with Dolphin

The controller rumble for GameCube does not work with the dolphin emulator config, while it does work with the retroarch config.

Migrate save states and saves to dedicated folder

Just an idea -

Can we make fourth folder called Emulation/saves ?
Would be nice to have our saves be visible and portable. Probably require sub folders per emulator.
Maybe we can do states too?

Unique IDs in Emulator configs (Dolphin)

Looking at the config for the Dolphin emulator an an example (Dolphin.ini), there's a hardcoded Analytics ID and a hard-coded WirelessMAC in the config file. I don't think that's a good idea, because it will make every SteamDeck install of Dolphin look identical.

Best would be to remove both of them from the config file in this repository (so Dolphin will auto-generate them once upon first boot), and while installing just check if they are already present in an existing config file and then keep the values as they are, so they don't change with each EmuDeck update.

Or, for the MAC address, have the script figure out the Steam Deck's actual MAC address and add that to the config.

(Also, is there a reason why in the logger config all the ultra-verbose logs are enabled and always written to the file system?

PPSSPP Standalone.

Just give the option on SRM

SD Card support is broken for sd cards not called mmcblk0p1

EmuDeck/install.sh

Lines 93 to 112 in bf9ba69

	sdCard=$(ls /run/media | grep -ve '^deck$' | head -n1)
	emulationPath="/run/media/${sdCard}/Emulation/"
	romsPath="/run/media/${sdCard}/Emulation/roms/"
	toolsPath="/run/media/${sdCard}/Emulation/tools/"
	toolsPathSed="\/run\/media\/${sdCard}\/Emulation\/tools\/"
	romsPathSed="\/run\/media\/${sdCard}\/Emulation\/roms\/"
	biosPath="/run/media/${sdCard}/Emulation/bios/"
	biosPathSed="\/run\/media\/${sdCard}\/Emulation\/bios\/"
	if [ $sdCard != "mmcblk0p1" ]; then
	text="You need to format your SD Card using Steam UI.<br>EmuDeck wont work if your SD card is not in ext4 format<br>Please come back when your SD Card is ready"
	zenity --error \
	--title="EmuDeck ERROR" \
	--width=250 \
	--text="${text}" &>> /dev/null
	exit
	fi
	fi

This block of code pulls the name of the SD Card for use in the script, and then it checks the sdcard name. If the sd card name isn't "mmcblk0p1" as referenced by line 103 above, it is treated as a failure.
I don't believe that's the correct behavior, and i believe the check block should be removed or you should look for /dev/mmcblk0p1 instead.
You can format an SD card with whatever name you like and it mounts and operates correctly.

for example mine is called "external" and here is the current mount parameter: "/dev/mmcblk0p1 on /run/media/external type ext4 (rw,noatime)"

Switch to flatpak I fixed it

Rom manager treating each bin file as separate game (PSX)

PSX games with multi track bins are showing in the rom manager as duplicates of the same game. Also happens if the psx image is a single bin and cue showing as two games on the list.

[question] Is it possible to add dlc to Yuzu using EmuDeck?

I don't see any roms when opening Yuzu directly. If I add the dlc to the switch folders they are picked up by steam rom manager and they show up in steam as duplicate games. Is there a best practice for organizing dlc and making it automatically launch with Yuzu?

--system resolves the query on the command line for me, and matches what the default is for the deck. (validated with a new user.)

We should probably add --system explicitly in case any other users have a similar setup or other wonkyness.

Currently only .rpx .wud and .wux files are supported in Cemu. If you don't want to use keys raw files make it easier like with Wii U UsbHelper to get raw files but they aren't supported yet

[feature request] xemu support

The xemu core is a original Xbox emulator that is LLE based emulation which uses a hdd,bios,eeprom (if none used it auto generates one that is bound to the hdd image) to run. They have a internal updating system to update the emulator and don't know if it would interfere with stuff. It supports arguments from command line during launch to boot a game. It currently can run on the steamdeck via the flatpack and I'm unsure if you can just build to arch Linux natively (no flatpak) would have to look at that (likely possible would have to ask about that on their discord).

Minor Limitation: from last I heard mango hud doesn't work on it and using other external fps/mspf measurement programs don't work because it just captures the emulated monitor refresh rate. Xemu has its own one in debug and in video. Other possible limitation idk if it is one I don't currently own a deck yet saving up but the update system.

Current development: currently the developer (mattboregson) is making a big picture mode where it is a gamepad experience for bigger screens hints the name.
