How to Install EmuDeck on Steam Deck
EmuDeck is the fastest way to set up emulation on your Steam Deck. It installs and configures over 40 emulators automatically, sets up ROM folders, and integrates with Steam so your emulated games appear in your library like native titles. The full install takes 15–30 minutes.
What EmuDeck Does
- Installs emulators for NES, SNES, GBA, N64, PS1, PS2, PS3, GameCube, Wii, Nintendo Switch, and 30+ more
- Configures each emulator with optimal Steam Deck settings automatically
- Creates standardised ROM folder structure on your microSD card
- Sets up Steam ROM Manager so emulated games appear as Steam games
- Includes RetroAchievements support for earning trophies in retro games
Before You Start
- A microSD card: EmuDeck stores ROMs on a separate card from your main SSD. A 256GB+ card is recommended
- ROMs: You need your own game files — EmuDeck does not provide them
- Internet connection: Required for the installer download
- 30 minutes of time
How to Install EmuDeck on Steam Deck
Step 1: Switch to Desktop Mode
From the Steam Deck main menu, press the Steam button → Power → Switch to Desktop.
Step 2: Open a Web Browser
In Desktop Mode, open Firefox or Chrome and go to emudeck.com. Click “Download for Steam Deck.”
Step 3: Run the Installer
Open the downloaded EmuDeck installer file. A setup wizard will launch and ask you a few questions — where to install (microSD is recommended), which emulators to include, and your display aspect ratio. Accept the defaults if you’re unsure.
Step 4: Wait for Installation
EmuDeck downloads and configures all selected emulators automatically. This takes 10–20 minutes depending on your internet speed. Don’t close the installer until it finishes.
Step 5: Add Your ROMs
After installation, EmuDeck creates a ROMs folder structure on your microSD (e.g., /Emulation/roms/snes/, /Emulation/roms/psx/). Copy your ROM files into the appropriate folders — one folder per system.
Step 6: Run Steam ROM Manager
Open EmuDeck and launch Steam ROM Manager. It scans your ROM folders and adds each game to your Steam library with cover art. This takes a few minutes to run.
Step 7: Return to Gaming Mode
Switch back to Gaming Mode (desktop shortcut or Power menu). Your emulated games now appear in a “Non-Steam” category in your library, each with its own artwork.
Adding BIOS Files
Some emulators (PS1, PS2, DS) require BIOS files to run accurately. EmuDeck creates a /Emulation/bios/ folder for these. Without BIOS files, some games may not launch or will have accuracy issues. BIOS files must be sourced from your own hardware — EmuDeck cannot provide them.
Updating EmuDeck
Run EmuDeck from Desktop Mode and select “Update” to fetch the latest emulator versions. EmuDeck updates frequently — checking monthly keeps your emulators current.
Bottom Line
EmuDeck turns a 30-minute setup process into a complete retro gaming library. It’s the standard recommended approach for Steam Deck emulation — widely documented, actively maintained, and works out of the box. Install it before doing anything else if emulation is part of your Steam Deck plans.
