COMPATIBILITY¶

-donut <x> <y>

-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>

-statdump <filename>

IWAD SEARCH PATHS¶

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¶

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).
