              Use  the  specified  magic values when emulating behavior caused by memory overruns
              from improperly constructed donuts. In Vanilla Doom this can  differ  depending  on
              the  operating system.  The default (if this option is not specified) is to emulate
              the behavior when running under Windows 98.

              Emulate a specific version of Doom.  Valid values are "1.2", "1.666", "1.7", "1.8",

       -spechit <n>
              Use the specified magic value when emulating spechit overruns.

       -statdump <filename>
              Dump statistics information to the specified file on the levels that  were  played.
              The  output  from this option matches the output from statdump.exe (see
              in the /idgames archive).


       -cdrom [windows only] Save configuration data and savegames in c:\doomdata, allowing  play
              from CD.

       -dumpsubstconfig <filename>
              Read  all  MIDI  files  from  loaded  WAD files, dump an example substitution music
              config file to the specified filename and quit.

       -mmap  Use the OS's virtual memory subsystem to map WAD files directly into memory.

       -nogui If specified, don't show a GUI window for error messages when the game  exits  with
              an error.


       To  play,  an  IWAD  file  is  needed.  This is a large file containing all of the levels,
       graphics, sound effects, music and other material that make up the game.  IWAD  files  are
       named according to the game; the standard names are:

       doom.wad, doom1.wad, doom2.wad, tnt.wad, plutonia.wad
              Doom, Doom II, Final Doom

       heretic.wad, heretic1.wad, hexen.wad, strife1.wad
              Heretic, Hexen and Strife (commercial Doom engine games).

       hacx.wad, chex.wad
              Hacx and Chex Quest - more obscure games based on the Doom engine.

       freedm.wad, freedoom1.wad, freedoom2.wad
              The Freedoom open content IWAD files.

       The following directory paths are searched in order to find an IWAD:

       Current working directory
              Any IWAD files found in the current working directory will be used in preference to
              IWADs found in any other directories.

              This environment variable can be set to contain a path to  a  single  directory  in
              which  to  look for IWAD files. This environment variable is supported by most Doom
              source ports.

              This  environment  variable,  if  set,  can  contain  a  colon-separated  list   of
              directories  in  which  to  look  for  IWAD  files,  or alternatively full paths to
              specific IWAD files.

              Writeable directory in the user's home directory. The path can be overridden  using
              the XDG_DATA_HOME environment variable (see the XDG Base Directory Specification).

       /usr/local/share/doom, /usr/local/share/games/doom, /usr/share/doom,
              /usr/share/games/doom  System-wide locations that can be accessed by all users. The
              path /usr/share/games/doom is a standard path that is supported by most Doom source
              ports.  These  paths can be overridden using the XDG_DATA_DIRS environment variable
              (see the XDG Base Directory Specification).

       The above can be overridden on a one-time basis by using the -iwad command line  parameter
       to provide the path to an IWAD file to use. This parameter can also be used to specify the
       name of a particular IWAD to use  from  one  of  the  above  paths.  For  example,  '-iwad
       doom.wad' will search the above paths for the file doom.wad to use.


       This section describes environment variables that control Crispy Doom's behavior.

              See the section, IWAD SEARCH PATHS above.

              When running in PC speaker sound effect mode, this environment variable specifies a
              PC speaker driver to use for sound effect playback.  Valid options are "Linux"  for
              the  Linux console mode driver, "BSD" for the NetBSD/OpenBSD PC speaker driver, and
              "SDL" for SDL-based emulated PC speaker playback (using the digital output).

              When using OPL MIDI playback, this environment variable specifies  an  OPL  backend
              driver  to  use.   Valid  options  are "SDL" for an SDL-based software emulated OPL
              chip,  "Linux"  for  the  Linux  hardware  OPL  driver,  and  "OpenBSD"   for   the
              OpenBSD/NetBSD hardware OPL driver.

              Generally speaking, a real hardware OPL chip sounds better than software emulation;
              however, modern machines do not often include one. If present, it may still require
              extra work to set up and elevated security privileges to access.


              The main configuration file for Crispy Doom.  See default.cfg(5).

              Extra  configuration  values  that  are  specific to Crispy Doom and not present in
              Vanilla Doom.  See crispy-doom.cfg(5).
