Updated January 8th, 2025: This guide now includes instructions for installing Decky Loader and Power Tools for optimal Game Gear performance on your Steam Deck.

Before You Begin: Preparation is Key

Before diving into EmuDeck, ensure you've taken these preparatory steps:

Enable Developer Mode

2. Navigate to the System menu.
3. In System Settings, enable Developer Mode.
4. Access the new Developer menu.
5. Under Miscellaneous, enable CEF Remote Debugging.
6. Restart your Steam Deck.

Essential Tools & Considerations

• External Storage: An A2 microSD card (or external HDD connected via dock) is crucial for storing ROMs and emulators, keeping your internal SSD free for Steam games.
• Input Devices: A keyboard and mouse simplify ROM transfers and artwork management.
• Legal ROMs: Ensure you legally own copies of any Game Gear ROMs you use.

Installing EmuDeck: Your Retro Gateway

With your Steam Deck prepared, let's install EmuDeck:

1. Switch to Desktop Mode (Steam button > Power > Switch to Desktop).
2. Open a web browser and download EmuDeck from its official website.
3. Select the SteamOS version and choose Custom Install.
4. During installation, select your SD card as the primary installation location.
5. Choose your desired emulators (we recommend RetroArch, Emulation Station, and Steam ROM Manager).
6. Enable Auto Save.
7. Complete the installation.

Essential EmuDeck Quick Settings

1. Open EmuDeck and navigate to Quick Settings.

4. Verify artwork and save changes to Steam.

Addressing Missing Artwork: A Troubleshooting Guide

If artwork is missing or incorrect:

• Use the "Fix" function in Steam ROM Manager to search for correct artwork.
• Rename ROMs to remove any numbers preceding the game title (this can interfere with artwork detection).
• Manually upload missing artwork by downloading images online and placing them in the Steam Deck's Pictures folder, then using the Upload function in Steam ROM Manager.

Playing Your Games and Optimizing Performance

Time to play!

1. Switch back to Gaming Mode.

Game Gear games may default to 30 FPS, causing slowdown. Adjust these settings for optimal performance:

1. Press the QAS button (three dots below the right trackpad).
