chocolate-doom.cfg(5)

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.

graphical_startup
    If non-zero, display the graphical startup screen.

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

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
    If non-zero, movement on the vertical joystick axis is inverted.
