The Sega Game Gear was a pioneering handheld console from the early 90s, designed to rival Nintendo's Game Boy. With its vibrant full-color display and innovative features, it stood out in the market. The Game Gear boasted a cartridge expansion for playing Sega Master System games, a TV tuner for turning it into a portable television, and a rich library of games. While it didn't achieve the longevity of its competitor, fans can relive the magic on the Steam Deck through EmuDeck. This guide will walk you through the process of installing EmuDeck and enjoying Game Gear games on your Steam Deck.
Updated January 8th, 2025, by Michael Llewellyn: The Sega Game Gear's design shares similarities with the Steam Deck, making it an ideal candidate for emulation on Valve's handheld PC. To optimize performance, EmuDeck developers recommend installing Power Tools via Decky Loader. This guide covers the steps for setting up Decky Loader, installing the Power Tools plugin, and ensuring compatibility after Steam Deck updates.
Before Installing The EmuDeck
Before diving into the world of retro gaming with EmuDeck, it's essential to prepare your Steam Deck and gather the necessary tools.
