Menu bar

The menu bar located at the top of the 86Box window provides controls for the emulated machine as a whole, its display, and the 86Box user interface.

Action

  • Keyboard requires capture: require the mouse to be captured for keypresses to be forwarded to the emulated machine. Enabling this option allows the use of keyboard combinations (such as Alt+Tab) on the host system while 86Box is focused.
  • Right CTRL is left ALT: let the right Ctrl key act as a left Alt key, to simulate some special keyboards where the Alt key is located on the right side of the space bar.
  • Hard Reset: force a reset of the emulated machine. Requires confirmation, which can be disabled by checking the Don't show this message again box.
  • Ctrl+Alt+Del: send a Ctrl+Alt+Del key combination to the emulated machine. You can alternatively press Ctrl+F12 to send that combination.
  • Ctrl+Alt+Esc: send a Ctrl+Alt+Esc key combination to the emulated machine.
  • Pause: pause emulation. Uncheck this option to resume emulation.

Note

Emulation is automatically paused when the emulated machine enters ACPI sleep mode.

  • Exit: quit 86Box. Requires confirmation, which can be disabled by checking the Don't show this message again box.

View

  • Hide status bar: hides the :doc:`status bar <statusbar>` at the bottom of the window.

  • Resizeable window: allow the 86Box window to be freely resized. Unchecking this option will also return the window to its normal size.

  • Remember size & position: automatically save the size and position of the 86Box window to the emulated machine's configuration file.

  • Renderer: select a graphical renderer for the emulated display.

    • SDL (Hardware) is recommended in most cases.
    • SDL (Software) and SDL (OpenGL) are known to perform better on some host systems. Try these if your system is struggling to maintain 100% emulation speed.
    • OpenGL (3.0 Core) allows for shader effects to be applied to the emulated display, however, it is not compatible with older integrated GPUs.

  • OpenGL options: configure the OpenGL (3.0 Core) renderer. This submenu will be available if that renderer is selected.

    • Target framerate: select the framerate at which the emulated display is updated. Sync with video uses the emulated display's current refresh rate.
    • VSync: enable vertical sync. Recommended if tearing artifacts are observed.
    • Select shader: load a .glsl shader file to apply on the emulated display. Many shaders are available for simulating CRT displays, VHS tapes and other aesthetics; the RetroArch glsl-shaders repository is a good place to start.
    • Remove shader: disable the currently-loaded shader.

Note

  • Shaders that take advantage of multipass and previous frames are not supported.
  • .cg and .cgp shaders are not supported either, as these formats are long deprecated.

  • Specify dimensions: open a window where an exact size (in pixels) for the emulated display can be set. If checked, the Lock to this size box prevents changes in the emulated display's resolution from overriding the specified size.

  • Force 4:3 display ratio: stretch the emulated display to a 4:3 aspect ratio, independently of the emulated machine's screen resolution.

  • Window scale factor: scale the emulated display to half (0.5x), normal (1x), 50% larger (1.5x) or double (2x) sizes.

  • Filter method: select the filtering method (Nearest or Linear) to be used when scaling the emulated display.

  • HiDPI scaling: automatically scale the emulated display to real size if your host system has a HiDPI display. This option can be used alongside Window scale factor above.

  • Fullscreen: enter full screen mode. Press Ctrl+Alt+Page Down to go back to windowed mode. You can also enter full screen mode by pressing Ctrl+Alt+Page Up.

  • Fullscreen stretch mode: select the picture mode to use when in full screen mode.

    • Full screen stretch: stretch the emulated display to completely fill the host display.
    • 4:3: stretch the emulated display to a 4:3 aspect ratio, then scale it to fit the host display.
    • Square pixels (keep ratio): scale the emulated display to fit the host display, without changing the aspect ratio.
    • Integer scale: scale the emulated display to the largest integer scale factor to fit the host display. This provides the highest possible picture quality, at the cost of black bars if the host display's resolution is not divisible by the emulated display's resolution.

  • EGA/(S)VGA settings: contains display settings specific to EGA, VGA and Super VGA video hardware.

    • Inverted VGA monitor: emulate a VGA monitor with inverted colors.
    • VGA screen type: select the VGA monitor type to emulate. Color, Grayscale, Amber, Green and White phosphor monitors can be selected.
    • Grayscale conversion type: select the color-to-grayscale conversion profile (BT.601, BT.709 or Average) to use when a grayscale monitor is selected.

  • CGA/PCjr/Tandy/EGA/(S)VGA overscan: add an overscan border around the display. This border is only added when emulating the specified video hardware types.

  • Change contrast for monochrome display: optimize the contrast of monochrome CGA monitors for 4-color operation.

Media

This menu lists all storage drives attached to the emulated machine, and provides the same controls that are accessible by clicking the respective drive's icon on the :doc:`status bar <statusbar>`.

Tools

Note

Discord integration will not be available if the Discord desktop app is not running, or if the included discord_game_sdk.dll file is missing from the 86Box directory.

  • Take screenshot: take a screenshot of the emulated display. Screenshots are saved as .png images in the screenshots subdirectory found in the emulated machine's directory.
  • Sound gain: open the :ref:`sound gain control <usage/statusbar:|sound| Sound>`, which is also accessible through the status bar.

  • Documentation: open the very documentation you're reading.
  • About 86Box: show credits and license information about 86Box.
