NAME

       crispy-doom - historically compatible Doom engine

SYNOPSIS

       crispy-doom [OPTIONS]

DESCRIPTION

       Crispy  Doom  is  a  port  of Id Software's 1993 game "Doom" that is designed to behave as
       similar to the original DOS version of Doom as is possible.

       -af <files>
              Simulates the behavior of NWT's -af  option,  merging  flats  into  the  main  IWAD
              directory.  Multiple files may be specified.

       -as <files>
              Simulates  the  behavior  of  NWT's  -as option, merging sprites into the main IWAD
              directory.  Multiple files may be specified.

       -deh <files>
              Load the given dehacked patch(es)

       -merge <files>
              Simulates the behavior of deutex's -merge option, merging  a  PWAD  into  the  main
              IWAD.  Multiple files may be specified.

       -mergedump <file>
              [crispy] experimental feature: in conjunction with -merge <files> merges PWADs into
              the main IWAD and writes the merged data into <file>

              files. [crispy] load DEHACKED lumps by default, but allow overriding

       -nwtmerge <files>
              Simulates the behavior of NWT's -merge option.  Multiple files may be specified.

DEMO OPTIONS

       -longtics
              Record a high resolution "Doom 1.91" demo.

       -maxdemo <size>
              Specify the demo buffer size (KiB)

       -strictdemos
              When  recording  or  playing back demos, disable any extensions of the vanilla demo
              format - record demos as vanilla would do, and play back demos as vanilla would do.

       -timedemo <demo>
              Play back the demo named demo.lmp, determining the framerate of the screen.

COMPATIBILITY

       -donut <x> <y>
              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.

       -gameversion <version>
              Emulate a specific version of Doom.  Valid values are "1.666", "1.7", "1.8", "1.9",
              "ultimate", "final", "final2", "hacx" and "chex".

       -pack <pack>
              Explicitly specify a Doom II "mission pack" to run  as,  instead  of  detecting  it
              based on the filename. Valid values are: "doom2", "tnt" and "plutonia".

       -setmem <version>
              Specify  DOS  version to emulate for NULL pointer dereference emulation.  Supported
              versions are: dos622, dos71, dosbox. The default is to  emulate  DOS  7.1  (Windows
              98).

       -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  ctrlapi.zip
              in the /idgames archive).

OBSCURE AND LESS-USED OPTIONS

       -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.

       -mb <mb>
              Specify the heap size, in MiB (default 16).

       -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.

IWAD SEARCH PATHS

       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.

       DOOMWADDIR
              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.

       DOOMWADPATH
              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.

       $HOME/.local/share/games/doom
              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/games/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.

ENVIRONMENT

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

       DOOMWADDIR, DOOMWADPATH
              See the section, IWAD SEARCH PATHS above.

       PCSOUND_DRIVER
              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).

       OPL_DRIVER
              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.

FILES

       $HOME/.local/share/crispy-doom/default.cfg
              The main configuration file for Crispy Doom.  See default.cfg(5).

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