NAME
chocolate-doom.cfg - Chocolate Doom configuration file
DESCRIPTION
chocolate-doom.cfg is a configuration file for chocolate-doom(6). This file acts as an
auxiliary configuration file; the main configuration options are stored in default.cfg,
which contains the same configuration options as Vanilla Doom (for compatibility).
chocolate-doom.cfg contains configuration options that are specific to Chocolate Doom
only.
chocolate-doom.cfg is normally stored in the user's home directory, as
~/.local/share/chocolate-doom/chocolate-doom.cfg. The path can be overridden using the
XDG_DATA_HOME environment variable (see the XDG Base Directory Specification).
The chocolate-setup(6) tool provides a simple to use front-end for editing chocolate-
doom.cfg.
FILE FORMAT
The file format is the same as that used for default.cfg(5).
CONFIGURATION VARIABLES
video_driver
Name of the SDL video driver to use. If this is an empty string, the default video
driver is used.
window_position
Position of the window on the screen when running in windowed mode. Accepted values
are: "" (empty string) - don't care, "center" - place window at center of screen,
"x,y" - place window at the specified coordinates.
fullscreen
If non-zero, the game will run in full screen mode. If zero, the game will run in
a window.
video_display
Index of the display on which the game should run. This has no effect if running in
windowed mode (fullscreen=0) and window_position is not set to "center".
aspect_ratio_correct
If non-zero, the screen will be stretched vertically to display correctly on a
square pixel video mode.
integer_scaling
If non-zero, forces integer scales for resolution-independent rendering.
window_width
Window width when running in windowed mode.
window_height
Window height when running in windowed mode.
fullscreen_width
Width for screen mode when running fullscreen. If this and fullscreen_height are
both set to zero, we run fullscreen as a desktop window that covers the entire
screen, rather than ever switching screen modes. It should usually be unnecessary
to set this value.
fullscreen_height
Height for screen mode when running fullscreen. See documentation for
fullscreen_width.
force_software_renderer
If non-zero, force the use of a software renderer. For use on systems lacking
hardware acceleration.
max_scaling_buffer_pixels
Maximum number of pixels to use for intermediate scaling buffer. More pixels mean
that the screen can be rendered more precisely, but there are diminishing returns
on quality. The default limits to 16,000,000 pixels, which is enough to cover 4K
monitor standards.
startup_delay
Number of milliseconds to wait on startup after the video mode has been set, before
the game will start. This allows the screen to settle on some monitors that do not
display an image for a brief interval after changing video modes.
show_endoom
If non-zero, the ENDOOM text screen is displayed when exiting the game. If zero,
the ENDOOM screen is not displayed.
show_diskicon
If non-zero, a disk activity indicator is displayed when data is read from disk. If
zero, the disk activity indicator is not displayed.
png_screenshots
If non-zero, save screenshots in PNG format. If zero, screenshots are saved in PCX
format, as Vanilla Doom does.
snd_samplerate
Sound output sample rate, in Hz. Typical values to use are 11025, 22050, 44100 and
48000.
snd_cachesize
Maximum number of bytes to allocate for caching converted sound effects in memory.
If set to zero, there is no limit applied.
snd_maxslicetime_ms
Maximum size of the output sound buffer size in milliseconds. Sound output is
generated periodically in slices. Higher values might be more efficient but will
introduce latency to the sound output. The default is 28ms (one slice per tic with
the 35fps timer).
snd_pitchshift
If non-zero, sound effects will have their pitch varied up or down by a random
amount during play. If zero, sound effects play back at their default pitch.
snd_musiccmd
External command to invoke to perform MIDI playback. If set to the empty string,
SDL_mixer's internal MIDI playback is used. This only has any effect when
snd_musicdevice is set to General MIDI output.
snd_dmxoption
Value to set for the DMXOPTION environment variable. If this contains "-opl3",
output for an OPL3 chip is generated when in OPL MIDI playback mode.
opl_io_port
The I/O port to use to access the OPL chip. Only relevant when using native OPL
music playback.
use_libsamplerate
Controls whether libsamplerate support is used for performing sample rate
conversions of sound effects. Support for this must be compiled into the program.
If zero, libsamplerate support is disabled. If non-zero, libsamplerate is enabled.
Increasing values roughly correspond to higher quality conversion; the higher the
quality, the slower the conversion process. Linear conversion = 1; Zero order hold
= 2; Fast Sinc filter = 3; Medium quality Sinc filter = 4; High quality Sinc filter
= 5.
libsamplerate_scale
Scaling factor used by libsamplerate. This is used when converting sounds
internally back into integer form; normally it should not be necessary to change it
from the default value. The only time it might be needed is if a PWAD file is
loaded that contains very loud sounds, in which case the conversion may cause sound
clipping and the scale factor should be reduced. The lower the value, the quieter
the sound effects become, so it should be set as high as is possible without
clipping occurring.
music_pack_path
Full path to a directory containing configuration files for substitute music packs.
These packs contain high quality renderings of game music to be played instead of
using the system's built-in MIDI playback.
timidity_cfg_path
Full path to a Timidity configuration file to use for MIDI playback. The file will
be evaluated from the directory where it is evaluated, so there is no need to add
"dir" commands into it.
gus_patch_path
Path to GUS patch files to use when operating in GUS emulation mode.
gus_ram_kb
Number of kilobytes of RAM to use in GUS emulation mode. Valid values are 256, 512,
768 or 1024.
vanilla_savegame_limit
If non-zero, the Vanilla savegame limit is enforced; if the savegame exceeds 180224
bytes in size, the game will exit with an error. If this has a value of zero,
there is no limit to the size of savegames.
vanilla_demo_limit
If non-zero, the Vanilla demo size limit is enforced; the game exits with an error
when a demo exceeds the demo size limit (128KiB by default). If this has a value
of zero, there is no limit to the size of demos.
vanilla_keyboard_mapping
If non-zero, the game behaves like Vanilla Doom, always assuming an American
keyboard mapping. If this has a value of zero, the native keyboard mapping of the
keyboard is used.
player_name
Name to use in network games for identification. This is only used on the
"waiting" screen while waiting for the game to start.
grabmouse
If this is non-zero, the mouse will be "grabbed" when running in windowed mode so
that it can be used as an input device. When running full screen, this has no
effect.
novert If non-zero, all vertical mouse movement is ignored. This emulates the behavior of
the "novert" tool available under DOS that performs the same function.
mouse_acceleration
Mouse acceleration factor. When the speed of mouse movement exceeds the threshold
value (mouse_threshold), the speed is multiplied by this value.
mouse_threshold
Mouse acceleration threshold. When the speed of mouse movement exceeds this
threshold value, the speed is multiplied by an acceleration factor
(mouse_acceleration).
mouseb_strafeleft
Mouse button to strafe left.
mouseb_straferight
Mouse button to strafe right.
mouseb_use
Mouse button to "use" an object, eg. a door or switch.
mouseb_backward

mouseb_prevweapon

mouseb_nextweapon
Mouse button to cycle to the next weapon.
dclick_use
If non-zero, double-clicking a mouse button acts like pressing the "use" key to use
an object in-game, eg. a door or switch.
joystick_guid
SDL GUID string indicating the joystick to use. An empty string indicates that no
joystick is configured.
joystick_index
Index of SDL joystick to use; this is only used in the case where multiple
identical joystick devices are connected which have the same GUID, to distinguish
between devices.
joystick_x_axis
Joystick axis to use to for horizontal (X) movement.
joystick_x_invert
If non-zero, movement on the horizontal joystick axis is inverted.
joystick_y_axis
Joystick axis to use to for vertical (Y) movement.
joystick_y_invert
