Mario DOS Demo Controls — DOS Keyboard Keys
Default keyboard bindings for Mario DOS Demo on our in-browser DOS emulator. Plug in a USB or Bluetooth gamepad to auto-detect mappings, or rebind any key from the emulator settings menu.
DOS games use the keyboard directly as the controller — there is no console-button mapping. Open the in-game documentation or check the game-specific options screen for the key layout used by this title.
Rebind any key from the EmulatorJS in-game settings menu (gear icon → Controls). A connected gamepad auto-maps to the same buttons.
