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

Updated January 8th, 2025, by Michael Llewellyn: Given the Steam Deck's resemblance to the Game Gear, running Game Gear games on it is fitting. EmuDeck developers recommend Power Tools via Decky Loader for optimal performance. This guide includes Decky Loader and Power Tools installation, plus a post-Steam Deck update fix.
