The Steam Deck is a versatile gaming device capable of running modern games and, with the help of EmuDeck, it can also serve as an excellent platform for playing retro games, including those from the original Game Boy. The charm of these classic games lies in their craftsmanship, despite the limitations of the Game Boy's monochrome display. Here's a comprehensive guide on how to install EmuDeck and enjoy Game Boy games on your Steam Deck.
