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 games are now easily playable on the Steam Deck thanks to EmuDeck. This guide provides a comprehensive walkthrough.

Updated January 8th, 2025, by Michael Llewellyn: For optimal Game Gear performance on the Steam Deck, EmuDeck developers recommend Power Tools via Decky Loader. This updated guide includes Decky Loader and Power Tools installation, plus a fix for maintaining compatibility after Steam Deck updates.

Recommended Items:

• An A2 microSD card (or external HDD connected via dock) for storing emulators and ROMs to preserve internal SSD space.
