How to increase size of DOSBox window?

  • go to dosbox installation directory (on my machine that is C:\Program Files (x86)\DOSBox-0.74 ) as you see the version number is part of the installation directory name.
  • run “DOSBox 0.74 Options.bat”
  • the script starts notepad with configuration file: here changewindowresolution=1600x800output=ddraw

(the resolution can’t be changed if output=surface – that’s the default).

  • safe configuration file changes.
