# This is the configurationfile for DOSBox 0.73. # Lines starting with a # are commentlines. # They are used to (briefly) document the effect of each option. [sdl] # fullscreen: Start dosbox directly in fullscreen. # fulldouble: Use double buffering in fullscreen. # fullresolution: What resolution to use for fullscreen: original or fixed size (e.g. 1024x768). # windowresolution: Scale the window to this size IF the output device supports hardware scaling. # output: What video system to use for output. # Possible values: surface, overlay, opengl, openglnb, ddraw. # autolock: Mouse will automatically lock, if you click on the screen. # sensitivity: Mouse sensitivity. # waitonerror: Wait before closing the console if dosbox has an error. # priority: Priority levels for dosbox. Second entry behind the comma is for when dosbox is not focused/minimized. (pause is only valid for the second entry) # Possible values: lowest, lower, normal, higher, highest, pause. # mapperfile: File used to load/save the key/event mappings from. # usescancodes: Avoid usage of symkeys, might not work on all operating systems. fullscreen=false fulldouble=true fullresolution=original windowresolution=1280x960 output=opengl autolock=true sensitivity=100 waitonerror=true priority=higher,normal mapperfile=mapper.txt usescancodes=true [dosbox] # language: Select another language file. # machine: The type of machine tries to emulate. # Possible values: hercules, cga, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe. # captures: Directory where things like wave, midi, screenshot get captured. # memsize: Amount of memory DOSBox has in megabytes. # This value is best left at its default to avoid problems with some games, # though few games might require a higher value. # There is generally no speed advantage when raising this value. language= machine=svga_s3 captures=capture memsize=64 [render] # frameskip: How many frames DOSBox skips before drawing one. # aspect: Do aspect correction, if your output method doesn't support scaling this can slow things down!. # scaler: Scaler used to enlarge/enhance low resolution modes. If 'forced' is appended,the scaler will be used even if the result might not be desired. # Possible values: none, normal2x, normal3x, advmame2x, advmame3x, advinterp2x, advinterp3x, hq2x, hq3x, 2xsai, super2xsai, supereagle, tv2x, tv3x, rgb2x, rgb3x, scan2x, scan3x. frameskip=1 aspect=true scaler=hq3xforced [cpu] # core: CPU Core used in emulation. auto will switch to dynamic if available and appropriate. # Possible values: auto, dynamic, normal, simple. # cputype: CPU Type used in emulation. auto is the fastest choice. # Possible values: auto, 386, 386_slow, 486_slow, pentium_slow, 386_prefetch. # cycles: Amount of instructions DOSBox tries to emulate each millisecond. Setting this value too high results in sound dropouts and lags. Cycles can be set in 3 ways: # 'auto' tries to guess what a game needs. # It usually works, but can fail for certain games. # 'fixed #number' will set a fixed amount of cycles. This is what you usually need if 'auto' fails. # (Example: fixed 4000) # 'max' will allocate as much cycles as your computer is able to handle # # Possible values: auto, fixed, max. # cycleup: Amount of cycles to increase/decrease with keycombo. # cycledown: Setting it lower than 100 will be a percentage. core=auto cputype=auto cycles=auto cycleup=500 cycledown=20 [mixer] # nosound: Enable silent mode, sound is still emulated though. # rate: Mixer sample rate, setting any device's rate higher than this will probably lower their sound quality. # Possible values: 22050, 44100, 48000, 32000, 16000, 11025, 8000, 49716. # blocksize: Mixer block size, larger blocks might help sound stuttering but sound will also be more lagged. # Possible values: 2048, 4096, 8192, 1024, 512, 256. # prebuffer: How many milliseconds of data to keep on top of the blocksize. nosound=false rate=48000 blocksize=4096 prebuffer=15 [midi] # mpu401: Type of MPU-401 to emulate. # Possible values: intelligent, uart, none. # mididevice: Device that will receive the MIDI data from MPU-401. # Possible values: default, win32, alsa, oss, coreaudio, coremidi, none. # midiconfig: Special configuration options for the device driver.
