Step 1 – Install EmuDeck on Your Steam Deck

Start by opening the browser on your Steam Deck. Visit the official website at 👉 www.emudeck.com and navigate to the downloads section. Download the SteamOS version of EmuDeck by following this direct link: EmuDeck Download for SteamOS.

Once the download is complete, double-click the file to begin installation. When prompted, choose Run. Opt for the Simple Install option rather than the Advanced one.

Next, decide where to install EmuDeck:

• Internal Storage
• microSD Card

After installation, you're ready to apply our BIOS Patch to enhance compatibility across various emulators.

Step 2 – Download the Retrogrados Gaming BIOS Patch

To streamline your setup, download the BIOS Patch from Retrogrados Gaming. Navigate to the BIOS section and select the Steam Deck version. This patch prepares most consoles for emulation, saving you a lot of time and effort.

Step 3 – Apply the BIOS Patch

Locate the Bios_Steam_Deck.rar file in your Downloads folder. Hold L2 and click on the file. From the menu, select Extract → Extract to…, and choose the directory: home/deck/Emulation/.

If you’re asked to overwrite files, select Yes to All. Now, most consoles are ready to emulate, except for the Nintendo Sw1tch, which requires additional setup.

Step 4 – Install the Nintendo Sw1tch Emulator (Ryujinx)

Open EmuDeck and go to Manage Emulators from the left sidebar. Find Ryujinx in the list and select Reinstall / Update. This will install the Ryujinx emulator.

Step 5 – Install Firmware and Keys for Nintendo Sw1tch

To complete the Nintendo Sw1tch setup, download the necessary Firmware and Keys from Retrogrados Gaming in the Sw1tch section. You’ll need:

• firmware.20.3.0.zip
• prod.keys

Open Desktop Mode on your Steam Deck, search for and launch Ryujinx. In the top menu, navigate to Actions → Install Keys and select the prod.keys file from your Downloads folder. Then, go to Actions → Install Firmware from ZIP and choose firmware.20.3.0.zip.

Configure Controller Input

Within Ryujinx, go to Options → Settings → Input. Set Steam Deck (0) as the input device and save your settings. You’re all set to start playing!

Step 6 – ROMs Download & Correct File Placement

For each game, ensure it’s placed in the correct platform folder. Here are some examples:

• Super Nintendo (SNES)

  • home/deck/Emulation/r0ms/snes/
  • Example: home/deck/Emulation/r0ms/snes/batmanreturns.smc

• Nintendo Sw1tch

  • home/deck/Emulation/r0ms/sw1tch/

• PlayStation 1 (PSX)

  • home/deck/Emulation/r0ms/psx/
