Introducing an Easy Guide to Running Sega Game Gear Games on Steam Deck

This guide details how to play Sega Game Gear games on your Steam Deck using EmuDeck, including optimizing performance and troubleshooting common issues.

Quick Links

The Game Gear, Sega's 90s handheld, boasted a full-color screen and innovative features like Master System game compatibility and a TV tuner. While not as enduring as the Game Boy, its game library thrives on the Steam Deck thanks to EmuDeck. This guide covers EmuDeck setup, Game Gear game play, and performance enhancement.

Updated January 8th, 2025, by Michael Llewellyn: This guide now includes installing Decky Loader and its Power Tools plugin for optimal Game Gear performance on the Steam Deck, along with a fix for maintaining compatibility after Steam Deck updates.

Before Installing EmuDeck

Before installing EmuDeck, prepare your Steam Deck with these steps:

Enabling Developer Mode

  1. Press the Steam button.
  2. Access the System menu.
  3. In System Settings, enable Developer Mode.
  4. Access the new Developer menu.
  5. In the Miscellaneous section, enable CEF Remote Debugging.
  6. Restart your Steam Deck.

Essential Items

  • External storage (A2 microSD card recommended) for emulators and ROMs to preserve internal SSD space for Steam games. Alternatively, an external HDD with a dock is possible.
  • Keyboard and mouse (highly recommended) for easier file transfers and artwork management.
  • Legally obtained Game Gear ROMs (copies of games you own).

Installing EmuDeck on the Steam Deck

With developer mode enabled, install EmuDeck:

  1. Switch to Desktop Mode.
  2. Open a web browser and download EmuDeck.
  3. Select the SteamOS version and "Custom Install."
  4. Choose your microSD card as the installation drive.
  5. Select desired emulators (RetroArch, Emulation Station, Steam ROM Manager recommended).
  6. Enable Auto Save.
  7. Complete the installation.

Quick EmuDeck Settings

  1. Open EmuDeck and go to Quick Settings.
  2. Ensure AutoSave is enabled.
  3. Enable Controller Layout Match.
  4. Set Sega Classic AR to 4:3.
  5. Turn on LCD Handhelds.

Transferring Game Gear ROMs and Using Steam ROM Manager

Transfer your ROMs and integrate them into Steam:

Transferring ROMs

  1. In Desktop Mode, use Dolphin File Manager.
  2. Navigate to your microSD card ("Primary").
  3. Go to the Emulation/ROMs/gamegear folder.
  4. Transfer your Game Gear ROMs into this folder.

Using Steam ROM Manager

  1. Open EmuDeck and select Steam ROM Manager.
  2. Close the Steam client if prompted.
  3. Follow the on-screen instructions, selecting the Game Gear icon and adding your games.
  4. Verify artwork and save to Steam.

Fixing Missing Artwork in EmuDeck

If artwork is missing or incorrect:

  • Use the "Fix" function in Steam ROM Manager, searching for the game title.
  • Remove any numbers preceding the game title in the ROM filename, as this can interfere with artwork detection.
  • Manually upload missing artwork via the browser, saving it to the Steam Deck's Pictures folder, then using the "Upload" function in Steam ROM Manager.

Access and optimize your Game Gear games:

  1. Switch to Gaming Mode.

  3. Enable per-game profiles and set the Frame Limit to 60 FPS.

Installing Decky Loader on the Steam Deck

Decky Loader enhances control and adds features:

  1. Switch to Desktop Mode.
  2. Download Decky Loader from its GitHub page.

  4. In Power Tools, disable SMTs, set Threads to 4, enable Manual GPU Clock Control, increase GPU Clock Frequency to 1200, and enable per-game profiles.

Troubleshooting Decky Loader After a Steam Deck Update

If Decky Loader disappears after an update:

  1. Switch to Desktop Mode.
  2. Download Decky Loader again from GitHub.
  3. Run the installer, selecting "Execute" (not "Open").
