I've installed Steam with Wine on my Mac. Then I installed Worms. It comes with an integrated DOSBox for Windows. For Windows only, unfortunately; although DOSBox is available for Linux and Mac as well. It works via the Steam client in Wine, but it's kind of a hassle to start Steam in Wine to run Worms in a DOSBox.

So I installed DOSBox for Mac via brew to run Worms directly. In

.wine/drive_c/Program Files (x86)/Steam/steamapps/common/Worms

and its sub-directories there are quite a few .BAT and .EXE files. I think I've tried them all

dosbox <file>

but no success so far in launching Worms. I think I read somewhere that Worms is DRM free. In theory this should work I think. So, how to run Worms in DOSBox?


Thanks to Stephen's answer, I found the file worms.conf. Using that running

dosbox -conf worms.conf

had the only effect of starting DOSBox in fullscreen mode. Then I've investigated the file a little and found this line:

imgmount d .\worms.CUE -t iso -fs iso

which I changed to

imgmount d ./worms.cue -t iso -fs iso

This had no effect however. What now?

This is the full content of worms.conf:

# This is the configurationfile for DOSBox 0.74. (Please use the latest version of DOSBox)# Lines starting with a # are commentlines and are ignored by DOSBox.
# They are used to (briefly) document the effect of each option.

#       fullscreen: Start dosbox directly in fullscreen. (Press ALT-Enter to go back)
#       fulldouble: Use double buffering in fullscreen. It can reduce screen flickering, but it can also result in a slow DOSBox.
#   fullresolution: What resolution to use for fullscreen: original or fixed size (e.g. 1024x768).
#                     Using your monitor's native resolution with aspect=true might give the best results.
#                     If you end up with small window on a large screen, try an output different from surface.
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
#                     (output=surface does not!)
#           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. (Press CTRL-F10 to unlock)
#      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. Resetmapper only works with the defaul value.
#     usescancodes: Avoid usage of symkeys, might not work on all operating systems.


# 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.


# 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, then 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.


#      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 decrease/increase with keycombo.(CTRL-F11/CTRL-F12)
# cycledown: Setting it lower than 100 will be a percentage.


#   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: 44100, 48000, 32000, 22050, 16000, 11025, 8000, 49716.
# blocksize: Mixer block size, larger blocks might help sound stuttering but sound will also be more lagged.
#            Possible values: 1024, 2048, 4096, 8192, 512, 256.
# prebuffer: How many milliseconds of data to keep on top of the blocksize.


#     mpu401: Type of MPU-401 to emulate.
#             Possible values: intelligent, uart, none.

# sbmixer: Allow the soundblaster mixer to modify the DOSBox mixer.
# oplmode: Type of OPL emulation. On 'auto' the mode is determined by sblaster type. All OPL modes are Adlib-compatible, except for 'cms'.

    I'm voting to close this question as off-topic because this is a Steam support issue, not a Unix and Linux issue – Alexander Jun 3 '19 at 21:14
  • This is NOT a Steam support issue, as I'm trying to do something NOT intended by Steam or the developer of the game. – user1785730 Jun 3 '19 at 21:17
  • As far as I can tell, you are using DOSbox correctly. I don't think this is a Unix and Linux issue. – Alexander Jun 3 '19 at 21:24
  • Where would you recommend me asking this question, if not here? – user1785730 Jun 3 '19 at 21:26

    Worms in DOSBox – eyoung100 Jun 3 '19 at 21:26

The general approach to run a Steam (or GOG, or ...) game which uses DOSBox, without using the provided DOSBox, is to find the configuration file that’s used, and start DOSBox with that:

cd ..../common/Worms
dosbox -conf fullscreen.conf

(replacing fullscreen.conf as appropriate).

This will ensure that everything is set up correctly — CD images and directories mounted, graphics options set, etc.

In this particular case, runworms.bat gives the complete recipe; adapted for Linux or macOS:

dosbox DriveC/goworms.bat -conf worms.conf -fullscreen -exit
