1. About
QuakeSpasm <http://quakespasm.sourceforge.net> is a modern, cross-
platform Quake engine based on FitzQuake
<http://www.celephais.net/fitzquake>.
It includes support for 64 bit CPUs and custom music playback, a new
sound driver, some graphical niceities, and numerous bug-fixes and
other improvements.
Quakespasm utilizes either the SDL or SDL2 frameworks, so choose which
one works best for you. SDL is probably less buggy, but SDL2 has
nicer features and smoother mouse input - though no CD support.
2. Downloads
o Project Downloads: http://quakespasm.sourceforge.net/download.htm
o Latest code repository:
https://sourceforge.net/p/quakespasm/quakespasm/ci/master/tree/
3. Hints
Visit the FitzQuake homepage <http://www.celephais.net/fitzquake> for
a full run-down of the engine's commands and variables.
o To disable some changes, use "quakespasm -fitz"
o Quakespasm's custom data is stored in "quakespasm.pak". Install
this file alongside your id1 directory to enable the custom console
background and other minor features.
o For different sound backend drivers use :
"SDL_AUDIODRIVER=DRIVER ./quakespasm"
where DRIVER may be alsa, dsp, pulse, esd ...
o Shift+Escape draws the Console.
o From the console, use UP to browse the command line history and TAB
to autocomplete command and map names.
o There is currently no CD Music volume support and SDL2 doesn't
support CD audio. cd_sdl.c needs replacing with cd_linux.c,
cd_bsd.c etc..
o In windows, alternative CD drives are accessible by
"quakespasm -cddev F" (for example)
o Quakespasm allows loading new games (mods) on the fly with
"game GAMENAME {-quoth/hipnotic/rogue}"
o Use "quakespasm -condebug" to save console log to "qconsole.log".
SDL2 builds no longer generate stdout.txt/stderr.txt.
3.1. Music Playback
Quakespasm can play various external music formats, including MP3, OGG
and FLAC.
o Tracks should be named like "track02.ogg", "track03.ogg" ... (there
is no track01) and placed into "Quake/id1/music".
o Unix users may need some extra libraries installed: "libmad" or
"libmpg123" for MP3, and "libogg" and "libvorbis" for OGG.
o As of 0.90.0, music is played back at 44100 Hz by default with no
need to adjust "-sndspeed".
o Use the "-noextmusic" option to disable this feature.
o See Quakespasm-Music.txt for more details.
3.2. Controller Support
The SDL2 variant of Quakespasm supports Xbox 360 style game
controllers.
The default configuration uses the left analog stick for movement and
the right for looking.
If your controller doesn't work you can try placing this file
https://raw.githubusercontent.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt
in your Quake directory, it is a community-maintained database that
adds support for more controllers to SDL2.
3.2.1. Cvars
o joy_deadzone - Fraction of the stick travel to be deadzone, between
0 and 1. Default 0.175.
o joy_deadzone_trigger - Fraction of trigger range required to
register a button press on the analog triggers, between 0 and 1.
Default 0.2.
o joy_sensitivity_yaw/pitch - Max angular speed in degrees/second
when looking. Defaults are 300 for yaw (turning left/right) and 150
for pitch (up/down).
o joy_exponent - For the look stick, the stick displacement (between
0 and 1) is raised to this power. Default is 3. A value of 1 would
give a linear relationship between stick displacement and fraction
of the maximum angular speed.
o joy_invert - Set to 1 to invert the vertical axis of the look
stick.
o joy_swapmovelook - Set to 1 to swap the left and right analog stick
functions. Default 0, move on the left stick, look on the right
stick.
o joy_enable - Set to 0 to disable controller support. Default 1.
3.2.2. Buttons
Some of the controller buttons are hardcoded to allow navigating the
menu:
o Back - alias for TAB
o Start - alias for ESC
o DPad, analog sticks - mapped to arrow keys
o A Button - alias for ENTER in menus
o B Button - alias for ESC in menus
These buttons can be bound normally:
o LTRIGGER - Left trigger
o RTRIGGER - Right trigger
o LSHOULDER - Left shoulder button
o RSHOULDER - Right shoulder button
o LTHUMB - Clicking the left thumbstick
o RTHUMB - Clicking the right thumbstick
o ABUTTON
o BBUTTON
o XBUTTON
o YBUTTON
quakespasm.pak contains a default.cfg which has been updated to give
some default bindings. L/R shoulder buttons are bound to weapon
switching, and L/R triggers are jump and attack.
The controller support started as Jeremiah Sypult's implementation in
Quakespasm-Rift and also uses ideas and code from LordHavoc
(DarkPlaces).
4. Compiling and Installation
See the Downloads section to get the sourcecode, then below for
platform specific instructions. Quakespasm can also be built with the
cross-platform Codeblocks.
Quakespasm's (optional) custom data is now stored in the file
quakespasm.pak. This file should be placed alongside your quakespasm
binary and id1 directory.
4.1. Linux/Unix
After extracting the source tarball, "cd Quake" and edit the Makefile
for music options.
Streaming music playback requires "libmad" or "libmpg123" for MP3, and
"libogg" and "libvorbis" for OGG files.
Then type "make" to compile the program, and copy the "quakespasm"
binary (and "quakespasm.pak") to your Quake game directory.
Compile time options include
o make DO_USERDIRS=1 to include user directories support
o make DEBUG=1 for debugging
o make SDL_CONFIG=/PATH/TO/sdl-config for unusual SDL installations
o make USE_SDL2=1 to compile against SDL2 instead of SDL-1.2
4.2. Windows
The QuakeSpasm developers cross-compile windows binaries using MinGW
<http://www.mingw.org> and MinGW-w64 <http://mingw-w64.sf.net>.
The project can also be built using Visual Studio 2005 (or newer).
4.3. Mac OS X
A Quakespasm App (including program launcher and update framework) can
be made using the Xcode template found in the MacOSX directory.
Alternatively, have a look at Makefile.darwin for more instructions on
building from a console.
4.4. Quake '2021 re-release'
QuakeSpasm 0.94.0 has initial support for playing the 2021 re-release
content: Copy the quakespasm binary to your rerelease installation and
run quakespasm as you normally do.
5. Changes
5.1. Changes in 0.94.3
o Handle sky textures with non-standard sizes and warn about them
(e.g. ad_tears)
o Allow loading textures not aligned to 16 pixels and warn about them
(eg. the horde2 map of Dimension of the Machine from 2021 rerelease
update/2.)
o Updated included SDL2 to latest version 2.0.18.
5.2. Changes in 0.94.2
o 2021 rerelease: Support for playing the latest update.
o 2021 rerelease: Fix pitch black models in lit areas in DOTM.
o 2021 rerelease: Fix black candles in the DOTM start map.
o 2021 rerelease: Look for QuakeEX.kpf under userdir, too.
5.3. Changes in 0.94.1
o Fix lightmap issues after vkQuake surface mark/cull optimizations
merge (sf.net bug/50)
5.4. Changes in 0.94.0
o Initial support for playing the 'Quake 2021 re-release' content

o Reject lit files if they're the wrong size (eg hipnotic/start.bsp
vs id1/start.lit or just a bsp that no longer has any coloured
lits, etc)
o External ent files are now versioned using 4 digit crc of the
original map's ents, like [email protected], which is much safer. The
old method (e.g. e1m1.ent) still works but isn't recommended.
o Support for external vis files.
o Save: remove CR/LFs from level name to avoids broken saves, e.g.
with autumn_sp map.
o Music: improvements to mp3 tag detection / skipping.
o Music: umx loader fix for malformed / crafted files.
o New console command music_jump: Jump to given order in music, like
Unreal's music change - only for module (tracker) music.

o Alpha-masked model support. (MF_HOLEY: 0x4000).
o Invalid skin index now draws skin 0 (WinQuake behaviour) instead of
blue checkerboard.
o Change default screenshot format to png. The 'screenshot' command
now supports optional format (tga, png or jpg) and quality (1-100)
arguments.
o Revert "always run" changes from 0.85.9 and move the QuakeSpasm
customizations to a new "cl_alwaysrun" cvar: Set to 1 in order to
scale forward/side/up speed by "cl_movespeedkey" (usually 2), and
to make "speedkey" act as "slowkey".
o Change the "always run" menu option to offer three choices:
off (cl_alwaysrun 0, cl_forwardspeed 200, cl_backspeed 200)
vanilla (cl_alwaysrun 0, cl_forwardspeed 400, cl_backspeed 400)
quakespasm (cl_alwaysrun 1, cl_forwardspeed 200, cl_backspeed 200)
o New "r_scale" cvar. Set to 2, 3, or 4 to render the view at 1/2,
1/3, or 1/4 resolution.
o New "r_viewmodel_quake" cvar. Set to 1 for WinQuake gun position
(from MarkV).

don't read uninitialized memory.
o Support for Open Watcom compiler.
o Update the third-party libraries.
5.8. Changes in 0.92.1
o Fixed large menu scale factors (was broken in 0.92.0).
o Fixed PAUSE key (was broken in 0.92.0).
o Updated some of the third-party libraries.
5.9. Changes in 0.92.0
o SDL2 Game Controller support.
o Contrast support with new "contrast" cvar, behaving the same as
MarkV. It may be a useful alternative to the existing gamma control
for laptops in a bright environment, etc. Raising contrast gives
less of a gray/washed out look than raising gamma, but at a
disadvantage: colors near white get clipped to white.
o RMQ protocol (999) support, adapted from RMQEngine.
o New "-protocol x" command line option. Accepted values for 'x' are
15 (NetQuake), 666 (FitzQuake, default), and 999 (RMQ).
o New "setpos" console command.
o New "vid_borderless" cvar for getting a borderless window.
o Increased MAX_MAP_LEAFS from 65535 to 70000 and MAX_LIGHTMAPS from
256 to 512 in order to handle the oms3 map pack.

o Worked around an OSX 10.6 driver bug when using FSAA, which was
leading to an unplayable HOM effect on the rest of the screen.
o Fix wrong trace endpoint from the tracepos console command.
o Updated some of the third-party libraries. Other fixes/clean-ups.
5.10. Changes in 0.91.0
5.10.1. Bugfixes
o Fix unwanted fog mode change upon video restart.
o Work around Intel 855 bug in status bar drawing with "r_oldwater 0"
and "scr_sbaralpha 0".
o Fix an obscure GLSL bug where changing gamma would result in the
screen turning to noise.

during map start wouldn't be drawn.
o Fix the order of OpenGL context creation and window creation in
SDL2 video.
o Fix a calling convention issue in windows DPI awareness function
pointers.
o Fix a random texture recoloring after video mode change.
o Fix a liquid turning to garbage after several video mode changes
and "r_oldwater 0".
o Fix a wrong alpha-sorting bug introduced in 0.90.1.

in 0.90.1).
o Prevent a possible buffer overflow in Cbuf_Execute (old Q1/Q2 bug).
o Prevent a possible vulnerability in MSG_ReadString (old Q1/Q2 bug).
5.10.2. Visual improvements
o New cvars r_lavaalpha, r_slimealpha, r_telealpha for fine-tuning
specific liquid opacities (from DirectQ/RMQEngine, non-archived,
default to 0), and new worldspawn keys _wateralpha, _lavaalpha,
_slimealpha, _telealpha, _skyfog (unique to Quakespasm, similar to
the behaviour of the "fog" worldspawn key).
o GLSL gamma is now supported on older hardware without NPOT
extension.
5.10.3. Interface improvements
o New r_pos command to show player position.
o NaN detection in traceline with "developer 1" set now warns instead
of errors.
5.10.4. Code cleanup / Other

5.10.5. Raised limits
o Default max_edicts 8192 (was 2048) and no longer saved to
config.cfg.
o Default heapsize 256 MB (was 64 MB).
o Default zone 4 MB (was 384 KB).
o Raised MAX_SFX to 1024 (was 512).

with retrojam1_skacky.bsp.
o Fix viewmodel not lerping on extended-limit maps.
o Fix crash on out-of-bounds skin number.
5.11.2. Performance
o Use multithreaded OpenGL on OS X for better performance.
o New, faster mdl renderer using GLSL. Disable with "-noglslalias".
5.11.3. Visual improvements
o New gamma correction implementation using GLSL. Fixes all known
gamma issues (affecting the full display, persisting after
quitting, or darkening the screen on OS X). Disable with
"-noglslgamma".
o Use high-quality water by default (r_oldwater 0).
o Shadows use stencil buffer to avoid overlapping artifacts (from
MarkV.)
o r_noshadow_list cvar added (from MarkV.)
5.11.4. Interface improvements
o Support pausing demo playback with the "pause" command.
o Autocompletion for "game", "record", "playdemo".
o Experimental windowed fullscreen mode available with
vid_desktopfullscreen 1 (only in SDL2 builds, takes effect upon
entering fullscreen mode the next time.)
o Silence "exceeded standard limit" messages unless developer cvar is
>= 1.
o Some spam moved from developer 1 to 2: "can't find tga/lit/ent",
"trying to load ent", "bad chunk length", "meshing",
"PR_AlocStringSlots: realloc'ing"
5.11.5. Code cleanup
o Clean up IDE project files to build on fresh systems.
o Update 3rd-party libraries.
5.12. Changes in 0.90.0

'make DO_USERDIRS=1' to enable it.
o SDL2 support. Disabled by default, 'make USE_SDL2=1' to enable it.
o Revised keyboard input code.
o Revised/improved the 'game' command, i.e. on-the-fly mod changing.
It now accepts an optional second argument for mission packs or
quoth support i.e. -hipnotic, -rogue, or -quoth. For example, for
WarpSpasm: "game warp -quoth"
o Command line: "-game {quoth/hipnotic/rogue}" is now treated the
same as -quoth, -hipnotic, or -rogue.
o Console speed now resolution-independent.
o Disabled gl_zfix, which caused glitches and is undesirable for new
maps. Replacement .ent files to fix z-fighting for several id1 maps
added to quakespasm.pak.
o PF_VarString buffer bumped to 1024, avoids truncated centerprints
from the 'In The Shadows' mod.
o Support for opengl non-power-of-two-textures extension (disable

for world and brush models (disable with command line: "-novbo".)
o Antialiasing (FSAA) support (command line: -fsaa x, where x can be
0, 2, 4, 8).
o Fence textures support.
o Dynamic light speedup. Speedup loading of tga and pcx external
images.
o Brush model drawing speedup.
o Support for BSP2 and 2PSB map formats.
o Support for Opus, FLAC, and tracker music (S3M, IT, UMX, etc.), as
compile-time options.
o Music and sfx now mixed at 44100 Hz to avoid downsampling music.
Low-pass filter applied to the sfx if -sndspeed is 11025 (the
default), to preserve the same sound quality as 0.85.9. New
-mixspeed option sets the rate for mixing sfx and music, and output
to the OS (default 44100), setting it to 11025 reverts to 0.85.9
behaviour. New snd_filterquality cvar, value can be between 1
(emulate OS X resampler) and 5 (emulate Windows resampler),
controls the sound of the low-pass filter.
o Better Hor+ field of view (FOV) scaling behavior.
o Better cross-map demo playback support.

using custom content.)
o Fix broken behavior upon gamedir changes if -basedir is specified
on the command line.
o NET_MAXMESSAGE and MAX_MSGLEN limits bumped to 64000.
o MAX_EFRAGS bumped to 4096, and MAX_CHANNELS to 1024.
o MAX_ENT_LEAFS bumped from 16 to 32 to work around disappearing or
flickering brush models in some situations. Also, if an entity is
visible from MAX_ENT_LEAFS or more leafs, we now always send it to
the client.
o Fix cvar cycle command not working sometimes.
o Host_Error upon missing models. (Prevents segmentation faults.)
o Change sv_aim default value to 1 (i.e. turn off autoaim)
o Add 'prev' and 'next' keywords to the 'cd' command.
o Work around a linux cdrom issue (playback might not start for a
while after a stop).
o Quakespasm content customization moved from engine-embedded into a
new optional quakespasm.pak file.
o Version bumped to 0.90.0 (because Quakespasm has a decent life of
it's own)
o Other fixes and clean-ups.
5.13. Changes in 0.85.9
o Fixes for several undefined behaviors in C code (gcc-4.8 support.)
o Implemented Hor+ style field of view (FOV) scaling, useful for
widescreen resolutions. Configured by new cvar fov_adapt: set it to
1 and your fov will be scaled automatically according to the
resolution. Enabled by default.
o Adjusted string buffers for PR_ValueString and friends to fix
crashes with excessively long global strings seen in some rude
mods.
o Toned down warning messages from PF_VarString() a bit.
o Fixed Fitzquake's map existence check in changelevel (used to leak
file handles which would end up in a Sys_Error() due to consuming
all free handles if many maps reside not in pak files.)
o Fixes/cleanups in chat mode handling. Client no longer gets stuck
in chat mode upon disconnect.
o Mouse grab/key_dest fixes and key cleanups.
o The "speedkey" now acts as "slowkey" when "always run" is on.

C-style /*..*/ comments.
o Changed lightmaps to GL_RGBA instead of GL_RGB.
o Better parse for opengl extensions list (from quakeforge.)
o Vsync saving/loading fixes.
o Fixed pointfile loading.
o Multiple cleanups in gl_vidsdl.c.
o Opus music decoding support (as an optional patch only.)
o Several other minor fixes/cleanups.
5.14. Changes in 0.85.8
o Made Quake shareware 1.00 and 1.01 versions to be recognized
properly.
