       prboom-plus - PrBoom+, a version of Doom for Unix, Linux and Windows systems


       prboom-plus [options] [values|files]


       PrBoom  is  a  version  of  the  first-person shooter game Doom, originally released by iD
       software  in  1993.   It  is  based  on  Boom,  a  version  of  Doom  adapted  by  TeamTNT
       (  for  Dos.  PrBoom uses the SDL library, meaning it can run on a
       variety of different systems, including Windows and Unix/X11.

       PrBoom+ is a Doom source port  developed  from  the  original  PrBoom  project.   It  adds
       uncapped  framerate, variable gamespeed, re-record, walkcam, chasecam, full mouselook, FOV
       and other features without loss of compatibility with original Doom.


       -complevel lvl
              This sets the compatibility mode that PrBoom+ runs in. If you need to change  this,
              see README.compat.

       -loadgame { 0,1,2,3,4,5,6,7 }
              Instructs PrBoom+ to load the specified saved game immediately.

       -warp { map | epis level }
              Tells PrBoom+ to begin a new game immediately. For Doom 1 or The Ultimate Doom, you
              must specify the episode and level number to begin at (epis is 1 for  Knee-Deep  in
              the  Dead,  2 for Shores of Hell, 3 for Inferno, 4 for Thy flesh Consumed; level is
              between 1 and 9). For Doom 2 or Final Doom, you must specify the map to  begin  at,
              which is between 1 and 32 (30 for German Doom 2).

       -skill n
              Tells PrBoom+ to begin the game at skill level n (1 for I'm Too Young To Die; 2 for
              Hey, Not Too Rough; 3 for Hurt Me Plenty; 4 for Ultra-Violent; 5 for Nightmare!).

              Tells PrBoom+ that monsters that die should respawn (come back  to  life)  after  a
              while. Not for the inexperienced.

       -fast  Tells  PrBoom+  to  make  all  the  monsters  move  and  react  faster. Not for the

              Tells PrBoom+ to include no monsters in the game.

              Disable applying cheats from dehacked files.


       -iwad iwadname
              Specifies the location of the  IWAD  file,  typically  doom.wad  or  doom2.wad  (or
              doom2f.wad). This tells PrBoom+ where the main .wad file that came with the version
              of Doom that you own is.

       -file wad1 ...
              Specifies a list of PWAD files to load in addition to the  IWAD  file.  PWAD  files
              modify  the  existing  Doom  game, by adding levels or new sounds or graphics. PWAD
              files are widely available for download; try  for

       -deh deh_file
              Tells PrBoom+ to load the dehacked patch deh_file.


       -record demofile
              Instructs  PrBoom+  to  begin  recording a demo, to be stored in demofile.lmp.  You
              should specify game options to specify which level and skill to record at.

       -playdemo demofile
              Play the recorded demo demofile.lmp.

       -timedemo demofile
              Play the recorded demo demofile.lmp, reporting information about the length of  the
              demo (in gametics) afterwards.

       -viddump filename
              Record a movie file, it requires external command-line encoding tools, oggenc2 (ogg
              vorbis audio encoder), x264 (h264 video encoder) and mkvmerge (mkv muxer).   It  is
              meant  to be used with -timedemo, e.g.  "prboom-plus -timedemo anydemo.lmp -viddump

       -fastdemo demofile
              Play the recorded demo demofile.lmp as fast as possible.  Useful  for  benchmarking
              PrBoom+, as compared to other versions of Doom.

       -ffmap num
              Fast  forward  the  demo (play at max speed) until reaching map num (note that this
              takes just a number, not a map name, so so -ffmap 7  to  go  fast  until  MAP07  or

       -warp x
              Warps  directly  to  the start of map x of a recording without rendering any of the
              play up to that point. Pressing Use (<Space> by default) during skipping shows  the
              current frame.

       -avidemo fileprefix
              Grabbing of the screenshots to frmXXXX.tga.

       -skipsec x
              Skip X secs during viewing of the demo.

       -warp x -skipsec y
              Will skip y seconds on level x.

       -recordfromto n.lmp m
              Play back the demo n.lmp, allowing the user to take over the controls at a point of
              his choosing, and save the resulting demo as m.lmp.

              Outputs a text-file called levelstat.txt containing level-by-level  information  on
              times, kills, items and secrets.

       -spechit xxx
              Provides a spechits magic number, overriding the program's default value.

              For playback of -nomonsters demos recorded with Doom.exe 1.2.

              For playback of -respawn demos recorded with Doom.exe 1.2.

       -auto  Enables  the  autoloading  of  wads  according  to the lmp file-name. See below for

       -emulate prboom_ver
              For viewing old desynching PrBoom demos with all recording bugs from  a  particular
              version  emulated.  For  example,  "-emulate  2.2.6"  would  be used to play back a
              desynching demo recorded with PrBoom 2.2.6. This would  be  instead  of  using  the
              various command-line options for each recording bug (see below) from that version.

              For   viewing   old   desynching   doom-compatible   PrBoom   demos  recorded  with
              "monster_avoid_hazards 1" in config.

              For viewing old desynching doom-compatible demos  recorded  with  old  versions  of
              PrBoom  (<  2.4.6)  or  PrBoom+  (< that are affected by the "remove slime
              trails" incompatibility.

              For viewing old desynching doom-compatible demos  recorded  with  old  versions  of
              PrBoom  (including 2.2.5 and 2.2.6) that padded a short REJECT with ones instead of

              For emulation of old buggy behaviour whereby Boom's generalized effects could  work
              instead of failing in a compatibility mode in the case of a bad action number.

              For  emulation  of  MBF_compatibility  behaviour  in  PrBoom 2.2.2 - 2.4.7, whereby
              things did not drop off ledges when they would have done in MBF.

              For emulation of old buggy behaviour whereby Boom's friction and bobbing code  were
              not faithfully replicated.

              For  emulation  of  Boom's  behaviour  with  respect  to the Monster Spawner, which
              differed slightly from that of "vanilla" Doom.

              For emulation of all bugs in demo compatibility mode in lxdoom.

              Forces the Boom DEH parser.

       -setmem system
              The desynch in fez1-924.lmp @ fez1.wad is gone, but you still need to add  "-setmem
              dosbox"  or  "-setmem  dos71"  command line parameter, because the default "dos622"
              memory layout causes a desynch.


       -net hostname[:port]
              Specifies that a TCP/IP network game is to be started. hostname is the name of  the
              machine  on which the network game server is running (prboom-plus-game-server). For
              more information about this, see prboom-plus-game-server(6)  and  the  README  that
              came  with  PrBoom+.  port  is  the  port  number on the remote machine to which to
              connect; if not specified, the default of 5030 (which is the  default  for  prboom-
              plus-game-server(6) ) is assumed.  The server will configure your PrBoom+ settings,
              so that all the players have the same game settings (skill, map etc).

       Also, the server may specify additional PWAD files to play with; if you do  not  have  the
       required  .WAD  file,  PrBoom+ will ask the server for a download path, and attempt to use
       wget(1) and if necessary unzip(1) to download and extract the required WAD.

       -port portnum
              Specifies the local port to use to communicate with the server in a netgame.

              No longer used. Tells PrBoom+ to begin a deathmatch game, but this is overridden by
              the server's settings. Only works for single play (!).

              Similar  to  -deathmatch,  but  implies a different set of rules for the deathmatch
              game. No longer used (specified by the server).

       -timer mins
              No longer used. Specifies that levels will end after mins minutes of  play  if  the
              level  is  still  being  played,  but is overridden by the server in a netgame. Not
              really useful for single play.

       -avg   Equivalent to -timer 20.

              Used to run a single-player network game, without  a  network  game  server.   This
              enables  network  game  items  &  options for an otherwise single-player game; some
              demos are recorded like this.


       -width w
              Specifies the width of the PrBoom+ window, in pixels. Default  is  320,  the  width
              must be greater than 320.

       -height h
              Specifies  the  height of the PrBoom+ window, in pixels. Default is 200, the height
              must be greater than 200.

       -viewangle n
              Causes the player view to be rotated by  a  given  offset  (specified  in  45degree
              increments, in the range 0..7) from the way the player is facing.

       -vidmode gl
              Use the OpenGL video mode. The default is to use the software video mode.

       -fullscreen, -nofullscreen
              These options toggle fullscreen mode. The default is fullscreen.

       -window, -nowindow
              This  pair  of  options also toggle fullscreen mode. They only take effect for this
              PrBoom+ session and do not alter your configuration file.

              For PrBoom+, this prevents it using the MITShm server  extension  for  passing  the
              screen  data  to  the  X server. This option may be required if the X server is not
              local. For lsdoom, this tells lsdoom not to use the accelerated graphics  functions
              that  SVGALib  provides  even when they are supported for your video card (normally
              this is autodetected).

       -1, -2, -3
              Specifies the scale factor by  which  to  enlarge  the  window.  The  default,  -1,
              displays the normal 320x200 pixel Doom screen (or whatever size is specified by the
              -width and -height parameters or in the config file for PrBoom+).  If  this  window
              is too small, try using -2 or -3 to enlarge the window.

              Suppress all graphical display. Only for debugging & demo testing.

       -aspect NxM
              For using a different aspect ratio; e.g. -aspect 5x4, -aspect 8x5 or -aspect 2x1.

       -videodriver name
              For  setting  up  the  videodriver  name that SDL will use (See SDL documentation).
              "-videodriver default" can be used to force SDL behaviour by default.

              Restores the original gamma after a crash.

       -geom NxM
              Basic syntax, for temporarily using a particular resolution without saving this  in
              the cfg; e.g. -geom 1280x1024.

       -geom WidthxHeight[w|f]
              Advanced  syntax,  w  -  windowed,  f - fullscreen. Examples: -geom 320x200f, -geom


              Disables all sound effects and  in-game  music.  This  prevents  the  sound  server
              loading, which lets the game run a little faster.

       -nosfx Disables  sound  effects  during  the  game.  This  does  not stop the sound server
              loading, however, so for best performance use -nosound.

              Disables playing of music in the game.

       -nojoy Disables joystick support.

              Prevents the mouse being grabbed by the PrBoom+ window.

              Forces  the  same  mouse  behaviour  as  when  recording  (i.e.  the  converse   of


       -config myconf
              Loads  an  alternative  configuration  file,  named  myconf. The default is prboom-
              plus.cfg(5), taken from the same directory as PrBoom+ was run from.

       -save savedir
              Causes PrBoom+ to save games in the  directory  specified  by  savedir  instead  of

       -shotdir shotdir
              Causes PrBoom+ to save screenshots in shotdir instead of the current directory.


              Development  mode.  Mostly  redundant  these  days,  but  it  does  force  non-lazy
              generation of texture lookups which can  be  useful  for  level  authors  debugging

       -debugfile debug_file
              Causes  some debugging information, mainly network info, to be written to the named
              file as PrBoom+ runs.

              Causes no rendering to be  done.  The  only  conceivable  use  of  this  is  (a)  a
              multiplayer server (b) to test the speed of the other routines in the program, when
              combined with -timedemo.

              Causes no copying to the screen from the rendering buffer  to  be  performed.   The
              only  conceivable  use of this is (a) a multiplayer server (b) to test the speed of
              the other routines in the program, when combined with -timedemo.

       -bexout bexdbg
              Causes diagnostics related to bex and dehacked file processing to be written to the
              names file.

              Use if PrBoom-Plus reports a buggy blockmap.
