Step 1: Prep Your Storage

Before using EmuDeck, decide where your ROMs and BIOS files will live. Most users either use:

The internal SSD for speed and simplicity
A microSD card (U3-rated, A2 class recommended) for expanded capacity

To format your SD card:

1. Insert the card into your pc handheld steam.

2. Open Settings > System.

3. Scroll to Format SD Card and press Format (this will erase all data).

Step 2: Switch to Desktop Mode

To begin the installation, you must leave the standard gaming interface. Press the Steam Button, navigate to Power, and select Switch to Desktop.

Pro Tip: Using an external wireless Bluetooth mouse and keyboard is highly recommended; navigating the Linux desktop with trackpads can be fiddly.

Pro Tip: Once downloaded, drag the file from your “Downloads” folder directly onto your Desktop; the script often fails to execute properly if run from the downloads folder.

Step 3: Install EmuDeck

After downloading:

Double-click the installer icon on your desktop and choose Custom Mode. This mode is essential for beginners because it allows you to select your storage location and configure specific emulator settings that Easy Mode skips.

Pro Tip: If the installer appears to be stuck, look at your taskbar for a glowing yellow terminal icon. A hidden popup window is likely waiting for you to click “Continue” or “OK”.

For users who want their retro library to feel like a native part of the SteamOS experience. Selecting this option during the custom setup process primarily enables the Steam ROM Manager to “inject” your games directly into your library.

NES / SNES
Game Boy / GBA / GBC

Step 5: Add Your ROMs and BIOS Files

1- ROM

Navigate to the emulation/roms folder created by EmuDeck. Drag and drop your game files into the folder that matches the console (e.g., put .gba files in the gba folder).

Use a USB drive or SD card to move files from your PC.
ROMs go into /emulation/roms/

Pro Tip: Use the Emu Compressor tool within EmuDeck to convert large .bin/.cue or .iso files into .chd format; this saves significant storage space while keeping games playable.

2- BIOS

consoles like PS2 and Switch require system BIOS or Firmware files to function. Open the emulation/bios folder on your storage drive and place your sourced files directly into the root of this folder.

BIOS files go into /emulation/bios/

Pro Tip: For PlayStation 1, the file must be named exactly SCPH1001.bin (case sensitive) and placed in the BIOS root or the /duckstation folder.

Detailed BIOS and Firmware Paths

Console	Path in `emulation/bios/`	Required Files/Notes
PlayStation 1	Root or `/duckstation`	`SCPH1001.bin`
PlayStation 2	Root	Multiple files (e.g., `SCPH-70012`)
Nintendo Switch	`/yuzu/keys` or `/ryujinx/system`	`prod.keys` and Firmware

• Return to Gaming Mode and launch the Emulation Station app from your library.
