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 ------ * **Right CTRL is left ALT:** let the right Ctrl key act as a left Alt key, to match 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. * **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. * **Exit:** quit 86Box. Requires confirmation. View ---- * **Resizeable window:** allow the 86Box window to be freely resized. Unchecking this option will return the window to its normal size. * **Remember size & position:** automatically save the size and position of the 86Box window to the configuration file. * **Renderer:** select a graphical renderer for the emulated display. *SDL (Hardware)* is recommended, but it may not work on some host systems, where *SDL (Software)* is the best option. * **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. * **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 fit 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. * **Integer scale:** scale the emulated display to the largest integer scale amount to fit the host display. This provides the highest possible picture quality, at the cost of black bars. * **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 phosphor, green phosphor and white phosphor monitors can be selected. * **Grayscale conversion type:** select the color-to-grayscale conversion profile to use when a grayscale monitor is selected. * **CGA/PCjr/Tandy/EGA/(S)VGA overscan:** enable an overscan border around the display for 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 removable media drives attached to the emulated machine, and provides the same controls that are accessible by clicking the respective drive icon on the :doc:`status bar `. Tools ----- * **Settings:** open the :doc:`Settings <../settings/index>` window. * **Update status bar icons:** enable the blinking lights on :doc:`status bar ` icons. Unchecking this may improve emulation performance on low-end host systems. * **Enable Discord integration:** enable Discord Rich Presence. Other Discord users will know that you're running 86Box, as well as the names of the virtual machine directory, emulated machine and emulated CPU you're using. * **Take screenshot:** take a screenshot of the emulated display. Screenshots are saved as PNG images in the ``screenshots`` directory. .. note:: Discord integration will not be available if the Discord desktop app is not running, or if the ``discord_game_sdk.dll`` library is not present in the 86Box directory. Help ---- * **Documentation:** open the very documentation you're reading. * **About 86Box:** show credits and license information about 86Box.
