This guide details how to install and use EmuDeck to play Sega Game Gear games on your Steam Deck, maximizing performance with Decky Loader and Power Tools.

Before You Begin: Essential Preparations

Before installing EmuDeck, ensure you've taken these steps:

• Enable Developer Mode: Access Steam > System > System Settings > Enable Developer Mode. Restart your Steam Deck after enabling CEF Remote Debugging in the Developer menu.
• Essential Equipment: An A2 microSD card (or external HDD connected via dock) is crucial for storing ROMs and emulators, freeing up your internal SSD. A keyboard and mouse are highly recommended for easier file management.
• Legal ROMs: Only use ROMs of games you legally own.

Installing EmuDeck

Follow these steps to install EmuDeck:

1. Switch to Desktop Mode (Steam button > Power > Switch to Desktop).
2. Download EmuDeck from their website.
3. Choose the SteamOS version and "Custom Install."
4. Select your microSD card (Primary) as the installation location.
5. Select your desired emulators (RetroArch, Emulation Station, Steam ROM Manager are recommended).
6. Enable "Auto Save."
7. Complete the installation.

Quick EmuDeck Settings

Within EmuDeck, navigate to Quick Settings and:

• Ensure "AutoSave" is enabled.
• Enable "Controller Layout Match."
• Set "Sega Classic AR" to 4:3.
• Turn on "LCD Handhelds."

Transferring ROMs and Using Steam ROM Manager

Get your Game Gear ROMs playing:

1. Transfer ROMs: In Desktop Mode, navigate to Primary > Emulation > ROMs > gamegear and copy your ROMs into this folder.
2. Steam ROM Manager (SRM): Open EmuDeck, launch SRM, and follow the on-screen prompts. Select the Game Gear parser, add your games, and parse them. Correct any artwork issues using SRM's built-in tools.

Fixing Missing Artwork

If SRM fails to find artwork:

• Use SRM's "Fix" function and search for the game title.
• Remove any numbers preceding the game title in the ROM filename.
• Manually upload artwork: Find the artwork online, save it to your Steam Deck's Pictures folder, and use SRM's "Upload" feature.

Playing Your Games

1. Switch back to Gaming Mode.
2. Access your Game Gear games via the Steam Library's Collections tab.
3. Adjust in-game performance settings (QAS button > Performance) to 60 FPS to avoid slowdown.

Enhancing Performance with Decky Loader and Power Tools

For optimal performance:

1. Install Decky Loader: Download from their GitHub page, and choose "Recommended Install" in Desktop Mode. Restart your Steam Deck.
2. Install Power Tools: Access Decky Loader via the QAM button, open the Decky Store, and install the Power Tools plugin.
3. Power Tools Settings: Within Power Tools, disable SMTs, set Threads to 4, enable Manual GPU Clock Control (set to 1200), and enable Per-Game Profile.

Fixing Decky Loader After a Steam Deck Update

If a Steam Deck update removes Decky Loader:

1. Switch to Desktop Mode.
2. Re-download Decky Loader from GitHub.
3. Run the downloaded file (choose "Execute," not "Open"). Enter your sudo password.
4. Restart your Steam Deck.
