Steam Deck: How To Run Sega Master System Games

Unleash the Power of Retro Gaming on Your Steam Deck: A Comprehensive Guide to EmuDeck and Sega Master System

The Sega Master System, a classic 8-bit console, boasts a library of fantastic games, including unique versions and titles not found on other platforms. This guide walks you through setting up EmuDeck on your Steam Deck to play these retro gems.

Before You Begin:

• Power Up: Ensure your Steam Deck is fully charged or connected to power.
• Storage: A high-speed microSD card (recommended) or external HDD is needed. Note that an external HDD reduces portability.
• Peripherals: A keyboard and mouse are highly recommended for easier navigation. If unavailable, use the on-screen keyboard (Steam + X buttons).

Enable Developer Mode:

Enabling Developer Mode is crucial for smooth emulator operation.

1. Access the Steam menu.
2. Navigate to System > System Settings.
3. Enable Developer Mode.
4. Access the Developer menu (bottom of the access panel).
5. Under Miscellaneous, enable CEF Remote Debugging. Important: Remember to check this after Steam Deck updates, as it can be disabled.
6. Restart your Steam Deck.

Installing EmuDeck in Desktop Mode:

1. Power down and switch to Desktop Mode.
2. Download EmuDeck using a browser (Chrome or Firefox).
3. Choose your SteamOS version and run the installer.
4. Select Custom Install.
5. Select your SD card (it will be renamed "Primary").
6. Choose your desired emulators (at least RetroArch for Sega Master System). Select Steam ROM Manager for easy library integration. Consider enabling "Configure CRT Shader for Classic 3D Games" for a retro aesthetic.
7. Complete the installation.

Transferring ROMs:

1. Open Dolphin File Manager.
2. Navigate to Removable Devices > Primary > Emulation > ROMS > mastersystem.
3. Copy your Sega Master System ROMs (.sms files) into this folder. Ignore the 'media' file.

Adding Games to Your Steam Library:

1. Open EmuDeck in Desktop Mode.
2. Launch Steam ROM Manager.
3. Select "Sega Master System."
4. Click "Add Games" then "Parse."
5. Verify game and artwork display.
6. Click "Save to Steam."

Fixing or Uploading Missing Artwork:

• Fixing: Click "Fix" on a missing cover. Steam ROM Manager will attempt to find artwork automatically. If not found, search manually and save.
• Uploading: Save artwork to the Steam Deck's Pictures folder. In Steam ROM Manager, click "Upload," select the image, and save.

Playing Your Games:

1. Switch to Gaming Mode.
2. Open your Steam Library.
3. Navigate to your Sega Master System collection.
4. Select a game and play!

Performance Enhancements:

For smoother gameplay:

1. Open a game and access the Quick Access Menu (QAM).
2. Go to Performance.
3. Enable "Use game profile."
4. Set Frame Limit to 60 FPS.
5. Enable Half Rate Shading.

Installing Decky Loader and Power Tools:

EmuDeck recommends Decky Loader and Power Tools for enhanced control. Follow the instructions within the guide for installation. Power Tools settings (disable SMTs, adjust threads, GPU clock control) are also detailed.

Fixing Decky Loader After Updates:

Steam Deck updates can affect Decky Loader. Reinstall Decky Loader from GitHub, using the "Execute" option and your pseudo-password (create one if needed).

Enjoy your retro gaming experience on the Steam Deck!
