COMPATIBILITY
-donut <x> <y>

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 "1.2", "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>

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

OBSCURE AND LESS-USED OPTIONS

from CD.

-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/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.
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
