Unlocking the Gaming Past with DOS_deck

In the modern era of gaming, we're spoiled for choice with instant access to games, thanks to game consoles and streaming services, all seamlessly controlled with our trusty gamepads. But let's rewind the clock. Long before these conveniences, there was an era where the gaming world was defined by the MS-DOS operating system, and it laid the foundation for what we enjoy today.

Between 1980 and 1995, MS-DOS reigned as the standard computer operating system. It was a period of innovation and creativity that introduced entirely new gaming genres. Wolfenstein pioneered the first-person shooter (FPS) genre, while Dune 2 set the stage for real-time strategy (RTS) games. Moreover, it was the birthplace of legendary franchises we adore today, including Grand Theft Auto, Fallout, Need for Speed and Warcraft.

However, as technology progressed, MS-DOS fell by the wayside, and in 2001, Microsoft ceased support for this iconic system. Many of these classic games became incompatible with modern versions of Windows, leaving a void in the hearts of gamers.

Enter a dedicated group of enthusiasts who weren't ready to let the classics fade into obscurity. They developed a PC emulator aimed at preserving the MS-DOS experience, and thus, DOSBox was born. This remarkable piece of software was the key to resurrecting the past.

DOSBox allowed these classic games to run, but it required installation on a computer, limiting accessibility. Fortunately, the magic of modern web technology came to the rescue. Some ingenious individuals managed to make DOSBox run within a web browser, giving rise to the marvelous software package known as JS-DOS.

DOS_deck is built upon the foundation of JS-DOS, which, in turn, relies on DOSBox. Together, they breathe new life into MS-DOS games by bringing them to your browser. However, there's a twist. Games from that era were designed for keyboard and mouse input, without established standards for interaction or control patterns. Here at DOS_deck, a tremendous effort was put into creating a seamless experience, enabling you to effortlessly navigate and play these games, ideally with the comfort of a controller in hand.

Rediscover a golden age of gaming with DOS_deck. It's the bridge between the past and the present, connecting you to a world of digital memories and timeless adventures.

A few tips

Playing these games in a browser is a blast. But browsers behave a certain way and it's good to know a few things:

  1. Browsers only play sound effects and music after you've "interacted" with the page at least once. So click or press a key once to activate audio.
  2. In many games, Escape activates a menu. But Escape also exits full screen in a browser. Therefore, you can press the equals key ("=") to simulate Escape at all times.
  3. Some browsers require you to click on the game once before you can actually use the mouse or emulate the mouse with a controller.

Steam Deck Installation

DOS_deck runs great on Chrome or Edge on a Steam Deck, but it needs a few steps to activate the controller properly. By default, browsers cannot detect the controller. Instead, controller input is received by Chrome and Edge as if you pressed a keyboard key. So follow these steps to install DOS_deck in Steam Deck game mode:

  1. Press the Steam button, select Power > Switch to Desktop.
  2. Open the Discover Software Center.

  5. Once it's installed, return to the Desktop. Select Application Launcher.
  6. Select Internet, right-click on Chrome or Edge and select Add to Steam.
  7. Check the box next to Chrome or Edge. Select Add Selected Programs.
  8. Back on the Desktop, open Application Launcher > System > Konsole (terminal window).
  9. Chrome or Edge needs access to the Steam Deck controller.
    Enter this command in Konsole and press Enter:

    For Chrome:
    flatpak override --user --filesystem=/run/udev:ro

    For Edge:
    flatpak override --user --filesystem=/run/udev:ro

  10. Open Steam
  11. Navigate to Chrome or Edge, right-click and select Properties.
  12. Change the name to DOS_deck
