# gus: Enable the Gravis Ultrasound emulation. Use 49716 for highest quality (set the mixer rate accordingly). # oplrate: Sample rate of OPL music emulation. # Possible values: default, compat, fast, old. compat or old might provide better quality (see oplrate as well). # oplemu: Provider for the OPL emulation. # Possible values: auto, cms, opl2, dualopl2, opl3, none. All OPL modes are Adlib-compatible, except for 'cms'. On 'auto' the mode is determined by sblaster type. # sbmixer: Allow the soundblaster mixer to modify the DOSBox mixer. # hdma: The High DMA number of the soundblaster. # dma: The DMA number of the soundblaster. # irq: The IRQ number of the soundblaster. # sbbase: The IO address of the soundblaster. # Possible values: sb1, sb2, sbpro1, sbpro2, sb16, none. This is usually the id of the device you want to use. # midiconfig: Special configuration options for the device driver. # Possible values: default, win32, alsa, oss, coreaudio, coremidi, none. # mididevice: Device that will receive the MIDI data from MPU-401. # Possible values: intelligent, uart, none. # prebuffer: How many milliseconds of data to keep on top of the blocksize. # blocksize: Mixer block size, larger blocks might help sound stuttering but sound will also be more lagged. # rate: Mixer sample rate, setting any device's rate higher than this will probably lower their sound quality. # nosound: Enable silent mode, sound is still emulated though. # cycledown: Setting it lower than 100 will be a percentage. # cycleup: Amount of cycles to increase/decrease with keycombo. # 'max' will allocate as much cycles as your computer is able to handle This is what you usually need if 'auto' fails. # 'fixed #number' will set a fixed amount of cycles. # It usually works, but can fail for certain games. # 'auto' tries to guess what a game needs. Setting this value too high results in sound dropouts and lags. # cycles: Amount of instructions DOSBox tries to emulate each millisecond. # Possible values: auto, 386, 386_slow, 486_slow, pentium_slow, 386_prefetch. # Possible values: auto, dynamic, normal, simple. auto will switch to dynamic if available and appropriate. # Possible values: none, normal2x, normal3x, advmame2x, advmame3x, advinterp2x, advinterp3x, hq2x, hq3x, 2xsai, super2xsai, supereagle, tv2x, tv3x, rgb2x, rgb3x, scan2x, scan3x. If 'forced' is appended,the scaler will be used even if the result might not be desired. # scaler: Scaler used to enlarge/enhance low resolution modes. # aspect: Do aspect correction, if your output method doesn't support scaling this can slow things down!. # frameskip: How many frames DOSBox skips before drawing one. # There is generally no speed advantage when raising this value. # though few games might require a higher value. # This value is best left at its default to avoid problems with some games, # memsize: Amount of memory DOSBox has in megabytes. # captures: Directory where things like wave, midi, screenshot get captured. # Possible values: hercules, cga, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe. # machine: The type of machine tries to emulate. # language: Select another language file. # usescancodes: Avoid usage of symkeys, might not work on all operating systems. # mapperfile: File used to load/save the key/event mappings from. # Possible values: lowest, lower, normal, higher, highest, pause. (pause is only valid for the second entry)

Second entry behind the comma is for when dosbox is not focused/minimized. # waitonerror: Wait before closing the console if dosbox has an error. # autolock: Mouse will automatically lock, if you click on the screen. # Possible values: surface, overlay, opengl, openglnb, ddraw. # output: What video system to use for output. # windowresolution: Scale the window to this size IF the output device supports hardware scaling. # fullresolution: What resolution to use for fullscreen: original or fixed size (e.g. # fulldouble: Use double buffering in fullscreen. # fullscreen: Start dosbox directly in fullscreen. # They are used to (briefly) document the effect of each option.

# Lines starting with a # are commentlines. # This is the configurationfile for DOSBox 0.73. Is it worth trying an older version of DosBox? In case it helps, here is my current config: I have tried running with the default DosBox settings as well as a variety of custom ones. Same guy as above - just created an account.
