Configuration:SDL

fullscreen = true | false: Start DOSBox directly in fullscreen.; Default is false.; (since 0.??)

fulldouble = true | false: Use double buffering in fullscreen.; Default is false.; (since 0.??)

fullresolution = width x height | original: The resolution to use for fullscreen. If original is specified, DOSBox will try to switch the screen resolution to best match the resolution request by the application. For example, if a game in DOSBox is requesting a graphics screen resolution of (320 x 240) while your desktop is (1280 x 1024), DOSBox will perform the switch or try other resolutions that closely matches it, e.g. (400 x 300) if (320 x 240) is not available.; Default is original.; (since 0.62)

windowresolution = width x height | original: Scale the window to this size IF the output device supports hardware scaling (i.e. any output other than surface). Note that the window size actually has a fixed 1.6 aspect ratio, so if you ask for 1280x1024, you'll end up with a squished 1280x800 window. original means 1x zoom and will resize as the emulator switches graphics modes.; Default is original.; (since 0.62)

output = surface | overlay | opengl | openglnb | ddraw: What to use for output.; Default is surface.; (since 0.??)

autolock = true | false: Mouse will automatically lock, if you click on the screen.; Default is true.; (since 0.??)

waitonerror = true | false: Wait before closing the console if DOSBox has an error.; Default is true.; (since 0.??)

priority = when-focused,when-minimzed: Priority levels for DOSBox. Second entry behind the comma is for when DOSBox is not focused/minimized. Valid priorities are: lowerest, lower, normal, higher, highest, and pause.; Default is higher,normal.; (since 0.??)

mapperfile = path-to-mapper-file: File used to load/save the key/event mappings from.; Default is mapper.txt.; (since 0.??)

usescancodes = true | false: Avoid usage of symkeys, might not work on all operating systems.; Default is true.; (since 0.??)

Deprecated parameters

fullfixed = true | false: Deprecated as of 0.65. See fullresolution.; (since 0.??)

fullwidth = width: Deprecated with 0.62. See fullresolution.; (since 0.61)

fullheight = height: Deprecated with 0.62. See fullresolution.; (since 0.61)
