Unleash 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 titles, including unique versions and ports of popular games like Golden Axe, Double Dragon, and Streets of Rage. Even more impressive are its surprisingly robust versions of titles like Mortal Kombat and Asterix & Obelix, which pushed the system's capabilities to near-16-bit levels.
While playing Sega Master System games on modern hardware can be challenging, the Steam Deck, combined with EmuDeck, makes it remarkably easy. This guide details the installation and optimization process.
Updated January 15, 2024: This guide has been updated to include Decky Loader and Power Tools, recommended by EmuDeck developers for enhanced performance and to address potential issues after Steam Deck updates.
