• Use the following commands:
  • ALT+ENTER = Full Screen.
  • ALT+PAUSE = Pause emulation.
  • CTRL+F1 = Show the keymapper configuration screen
  • CTRL+F4 = Update cached information about mounted drives. Useful if you changed something on a mounted drive outside of DOSBox. Also cycles through disk images mounted using IMGMOUNT.
  • CTRL+F5 = Save a screenshot (goes to capture folder).
  • CTRL+ALT+F5 = Start/Stop recording of AVI video. NOTE: You may well have some problems with this, please see Recording Video for more information.
  • CTRL+F6 = Start/Stop recording sound output to a wave file (goes to capture folder).
  • CTRL+ALT+F7 = Start/Stop recording of OPL commands.
  • CTRL+ALT+F8 = Start/Stop the recording of raw MIDI commands.
  • CTRL+F7 = Decreases frameskip
  • CTRL+F8 = Increases Frameskip
  • CTRL+F9 = Kill (close) DOSBox.
  • CTRL+F10 = Capture/Release the mouse (if you need to use the mouse within DOSBox).
  • CTRL+F11 = Slows down the game
  • CTRL+F12 = Speeds up the game
  • ALT+F12 = Unlock speed (turbo button).
  • cycles=xxxx = cpu cycles (default = auto). Try cycles=max.
  • core=auto, dynamic, normal, ...
  • Graphics emulation (speed up)
    • VGA emulation is a demanding part of DOSBox in terms of actual CPU usage. Increase the number of frames skipped (in increments of one) by pressing CTRL-F8. Your CPU usage should decrease when using a fixed cycle setting, and you will be able to increase cycles with CTRL-F12. You can repeat this until the game runs fast enough for you. Please note that this is a trade-off: you lose in fluidity of video what you gain in speed.
    • Press CTRL+ALT+DEL to open the Task Manager, and click the Performance tab. Start by pressing CTRL+F12 until your CPU Usage level begins to go above 95/o. After that, if you still need a performance boost, hit CTRL+F8 to have DOSBox not render some frames. The console window will display all of the changes you' ve made, and the top of the game window will display the current settings. Adjust these settings as needed until your game goes smoothly. Please keep in mind that not all games will run smoothly on DOSBox.
