RetroArch Configuration

Back to the Top

  • Type of Emulator: Flatpak
  • Config Location: /home/deck/.var/app/org.libretro.RetroArch/config/retroarch
  • Storage Location: Emulation/storage/retroarch
  • ROMs: Refer to the Cheat Sheet
  • BIOS: Refer to the Cheat Sheet
  • Saves:
    • Symlink: Emulation/saves/retroarch/saves
    • Target Location: /home/deck/.var/app/org.libretro.RetroArch/config/retroarch/saves/
  • Save States:
    • Symlink: Emulation/saves/retroarch/states
    • Target Location: /home/deck/.var/app/org.libretro.RetroArch/config/retroarch/states/
  • Systems Location: Emulation/bios
    • Libretro wikis or guides may mention either placing your files into a System folder or creating a folder in the System directory. Though Emulation/bios is not named System, treat it as the System folder for RetroArch
      • For example, the Libretro wiki page for Dreamcast expects you to create a dc folder in RetroArch's system directory. Instead, create a dc folder in Emulation/bios and place any required files in Emulation/bios/dc
        • Dreamcast Example

Note: ~/.var is an invisible folder by default. In Dolphin (file manager), click the hamburger menu in the top right, click Show Hidden Files to see these folders.

Works With

  • Steam Rom Manager
  • EmulationStation-DE

RetroArch Folder Locations

Back to the Top

These file locations apply regardless of where you chose to install EmuDeck (to your internal SSD, to your SD Card, or elsewhere). Some emulator configuration files will be located on the internal SSD as listed below.

$HOME refers to your home folder. If you are on a Steam Deck, this folder will be named /home/deck (you will likely not see deck in the file path when navigating using the file manager).

Paths beginning with Emulation/.. correspond to your EmuDeck install location. If you installed on an SD Card, your path may be /run/media/mmcblk0p1/Emulation/roms/... If you installed on your internal SSD, your path may be /home/deck/Emulation/roms/..

Note: Folders with a . (.var, .local, .config, etc.) at the beginning are hidden by default. In Dolphin (file manager), click the hamburger menu in the top right, click Show Hidden Files to see these folders.

How to Launch RetroArch in Desktop Mode

Back to the Top

How to Launch RetroArch in Desktop Mode

  • Launch RetroArch from the Applications Launcher (Steam Deck icon in the bottom left of the taskbar)
  • Launch the script from Emulation/tools/launchers, retroarch.sh
  • Launch the emulator from Steam after adding it via the Emulators parser in Steam Rom Manager

A Breakdown of Overrides

Back to the Top

  1. Global = Everything.
  2. Core = Anything run by a specific core.
  3. Content Directory = Any ROM in a specific directory.
    • These are used for the EmuDeck applied shaders.
  4. Game = that specific ROM.

As you get lower in this list it takes precedence, so if you do nothing but set a core shader preset, it will not override the content directory preset already applied.

RetroArch Tips and Tricks

Back to the Top

How to Optimize Storage (Compression Tool)

Back to the Top

To optimize storage, you can use the EmuDeck Compressor within EmuDeck.

The EmuDeck Compressor will compress your Dreamcast, Playstation 1, Sega/MegaCD, 3DO, Saturn, TurboGraphix/PCEngineCD, PC-FX, Amiga CD32, and NeoGeoCD ROMs to CHD. If your ROM is a BIN/CUE, the Compression Tool will only compress it if you have both the BIN and the CUE files for a ROM. If the ROM is in a zip file or is missing a paired BIN or CUE file, the Compression Tool will not detect the ROM.

After running the EmuDeck Compression Tool, re-run Steam ROM Manager to update your ROM shortcuts to the newly compressed ROM.

How to Change Shaders

Back to the Top

How to Download/Update Shaders

  1. Open RetroArch
    • You may also do this in game by pressing L3 and R3
  2. Open the Main Menu
  3. Select Online Updater
  4. Select Update Slang Shaders

How to Apply New Shaders if Shaders Are Already Applied

  2. Open the Quick Menu with L3 and R3
  3. Select Shaders
  4. In Shaders, select the Remove button
  5. Select Remove Content Directory Preset
  6. Close RetroArch and reload content. No shaders will be applied
    • Yes, it may be hard to see, but no more LCD squares
  7. If you want to select a different shader, open the Shaders menu again, and select your preferred settings/shaders. When you are satisfied, select the Save button, and click Save Content Directory Preset

How to Apply Shaders if Shaders Are Not Already Applied

  5. Select a shader
  6. Back out to the Shaders menu
  7. Click Save, click Save Content Directory Preset
  8. Back out to the Quick Menu, click Overrides, and click Save Content Directory Overrides

Override Precedence

The order they are listed in is the order they take precedence, from most general to most specific.

  1. Global = Everything.
  2. Core = Anything run by a specific core.
    • Keep in mind that some cores run multiple systems. For example, the Gambatte RetroArch core plays both Game Boy and Game Boy color games. If you use the Core override, it will apply to both systems.
  3. Content Directory = Any ROM in a specific directory.
    • The folders can be found in your Emulation folder, on the storage device you selected for EmuDeck.
    • These are used for the EmuDeck applied shaders.
  4. Game = that specific ROM.

As you get lower in this list it takes precedence, so if you do nothing but set a core shader preset, it will not override the content directory preset already applied.

How to Roll Back RetroArch to an Older Version

Back to the Top

If you do not have access to a mouse and keyboard for the below section, use L2 to right click and R2 to left click. Alternatively, remote into your Steam Deck using one of the methods found in the FAQ, How do I remotely control my Steam Deck?.

  1. In Desktop Mode, open Konsole
  2. To see a list of prior versions of the emulator, type:
    • flatpak remote-info --log flathub org.libretro.RetroArch
  3. If Konsole prompts you to select system or user, enter 2 to select user
  4. Konsole will list a list of previous versions for the flatpak. The important line for each version is the Commit: line. The Commit: line will have a long accompanying alphanumeric string (the “commit” code). Copy the string for the version you want to downgrade to.
    • Using Citra as an example:
      • How to Roll Back Flatpaks: 1
  5. To downgrade to the version you want:
    • flatpak update --commit=put_commit_code_here org.libretro.RetroArch
    • Replace put_commit_code_here with the actual code you located in Step 2.
      • Using Citra as an example:
        • How to Roll Back Flatpaks: 2

If the above steps did not work and you are getting an error message along the lines of Flatpak not installed, your Flatpak is likely installed at the system level instead. Select one of the below solutions:

Solution 1: Open the EmuDeck application, click the Manage Emulators page, select the emulator in question, and click Reinstall / Update.

Solution 2: Add sudo in front of the commands written in Step 2 and Step 5. In Step 2, write sudo flatpak remote-info --log flathub com.github.Rosalie241.RMG and in Step 5, write sudo flatpak update --commit=put_commit_code_here com.github.Rosalie241.RMG.

How to Configure Controls for Fuse

Back to the Top

You will want to set a joystick in the quick menu/controls/port one.

RetroArch sets it controller by default, but thats useless for a computer.

I always suggest setting it to "Kempston" and saving a core remap.

Kempston works for a lot of games so is a good base, but it may need changing on a game by game basis, which is easy enough.

If you load a game and kempston doesnt work, just head back to quick menu/controls/port one, and try one of the other joysticks.

When you find one that works save that as a game remap.

Bear in mind though the speccy was a computer, and some games will be keyboard only, you may be able to work around that via steam input.
