QuakeSpasm
Page last edited: July 2024.
About
QuakeSpasm is a modern cross-platform Quake engine based on 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 SDL-1.2 or SDL2 frameworks, choose one which works best for you. SDL2 has nicer features, smoother mouse input and better support for newer operating systems, but no CD-ROM support.
Downloads
Project Downloads: http://quakespasm.sourceforge.net/download.htm
Latest code repository: https://sourceforge.net/p/quakespasm/quakespasm/ci/master/tree/
Github mirror: https://github.com/sezero/quakespasm
Hints
Visit the FitzQuake homepage https://celephais.net/fitzquake/ for a full run-down of the engine's commands and variables.
To disable some changes, use "quakespasm -fitz"
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.
For different sound backend drivers use : "SDL_AUDIODRIVER=DRIVER ./quakespasm" where DRIVER may be alsa, dsp, pulse, esd ...
Shift+Escape draws the Console.
From the console, use UP to browse the command line history and TAB to autocomplete command and map names.
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..
In windows, alternative CD drives are accessible by "quakespasm -cddev F" (for example)
Quakespasm allows loading new games (mods) on the fly with "game GAMENAME {-quoth/hipnotic/rogue}"
Use "quakespasm -condebug" to save console log to "qconsole.log". SDL2 builds no longer generate stdout.txt/stderr.txt.
Music Playback:
Quakespasm can play various external music formats, including MP3, OGG and FLAC.
Tracks should be named like "track02.ogg", "track03.ogg" ... (there is no track01) and placed into "Quake/id1/music".
Unix users may need some extra libraries installed: "libmad" or "libmpg123" for MP3, and "libogg" and "libvorbis" for OGG.
Use the "-noextmusic" option to disable this feature.
As of 0.90.0, music is played back at 44100 Hz by default with no need to adjust "-sndspeed".
See Quakespasm-Music.txt for more details.
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.
Controller Support - Cvars:
joy_deadzone_look - Fraction of look stick travel to be deadzone, between 0 and 1. Default is 0.175.
joy_deadzone_move - Same as above, but for the move stick. Default is 0.175.
joy_deadzone_trigger - Fraction of trigger range required to register a button press on the analog triggers, between 0 and 1. Default 0.2.
joy_outer_threshold_look - Outer deadzone for the look stick, between 0 and 1. Default 0.02.
joy_outer_threshold_move - Outer deadzone for the move stick, between 0 and 1. Default 0.02.
joy_sensitivity_yaw/pitch - Max angular speed in degrees/second when looking. Defaults are 240 for yaw (turning left/right) and 130 for pitch (up/down).
joy_exponent - For the look stick, the stick displacement (between 0 and 1) is raised to this power. Default is 2. A value of 1 would give a linear relationship between stick displacement and fraction of the maximum angular speed.
joy_exponent_move - Same as joy_exponent but for the move stick. Default is 2.
joy_invert - Set to 1 to invert the vertical axis of the look stick.
joy_swapmovelook - Set to 1 to swap the left and right analog stick functions. Default is 0, move on the left stick, look on the right stick.
joy_enable - Set to 0 to disable controller support. Default is 1.
Controller Support - Buttons:
Some of the controller buttons are hardcoded to allow navigating the menu:
These buttons can be bound normally:
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/code from LordHavoc's DarkPlaces.
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.
Compiling for 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
make DO_USERDIRS=1 to include user directories support
make DEBUG=1 for debugging
make SDL_CONFIG=/PATH/TO/sdl-config for unusual SDL installations
make USE_SDL2=1 to compile against SDL2 instead of SDL-1.2
Compiling for Windows:
QuakeSpasm developers cross-compile windows binaries using MinGW-w64 http://mingw-w64.sf.net and MinGW https://mingw.osdn.io. The project can also be built using Microsoft Visual Studio 2005 and newer versions.
Compiling for 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.
Quake '2021 re-release':
QuakeSpasm 0.94 has support for playing the 2021 re-release content: Copy the quakespasm binary to your rerelease installation and run as you normally do.

New "find" / "apropos" command, searches for commands/cvar names for the given substring (from Spike).
New "randmap" command for loading a random map.
New "gl_cshiftpercent_contents", "gl_cshiftpercent_damage", "gl_cshiftpercent_bonus", "gl_cshiftpercent_powerup" cvars for tuning the strength of specic view blends.
GL2 renderer: use a GLSL shader for world faces. Fixes reports of integrated+discrete GPU laptops having inconsistent fog rendering.

Updated some of the third-party libraries.
Changes in 0.92.0:
SDL2 Game Controller support.
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.
RMQ protocol (999) support, adapted from RMQEngine.
New "-protocol x" command line option. Accepted values for 'x' are 15 (NetQuake), 666 (FitzQuake, default), and 999 (RMQ).
New "setpos" console command.
New "vid_borderless" cvar for getting a borderless window.

Fix wrong trace endpoint from the tracepos console command.
Updated some of the third-party libraries. Other fixes/clean-ups.
Changes in 0.91.0:
Bugfixes:
Fix unwanted fog mode change upon video restart.
Work around Intel 855 bug in status bar drawing with "r_oldwater 0" and "scr_sbaralpha 0".
Fix an obscure GLSL bug where changing gamma would result in the screen turning to noise.
Fix GLSL gamma causing the tiled screen border to turn white when "sizedown" is used.

Fix the order of OpenGL context creation and window creation in SDL2 video.
Fix a calling convention issue in windows DPI awareness function pointers.
Fix a random texture recoloring after video mode change.
Fix a liquid turning to garbage after several video mode changes and "r_oldwater 0".
Fix a wrong alpha-sorting bug introduced in 0.90.1.
Fix "flush" command not reloading mdl's from disk (bug introduced in 0.90.1).
Prevent a possible buffer overflow in Cbuf_Execute (old Q1/Q2 bug).
Prevent a possible vulnerability in MSG_ReadString (old Q1/Q2 bug).
Visual improvements:
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).
GLSL gamma is now supported on older hardware without NPOT extension.
Interface improvements:
New r_pos command to show player position.
NaN detection in traceline with "developer 1" set now warns instead of errors.
Code cleanup / Other:
Raised limits:
Default max_edicts 8192 (was 2048) and no longer saved to config.cfg.
Default heapsize 256 MB (was 64 MB).
Default zone 4 MB (was 384 KB).
Raised MAX_SFX to 1024 (was 512).
Changes in 0.90.1:
Bugfixes:
Fix dynamic light artifact where changing lightmap are rendered one frame late (bug introduced in 0.90.0).
Fix texture memory leak when changing video modes with SDL2.
Fix a rare incorrect mdl lighting on 64-bit builds. (details here: https://forums.insideqc.com/viewtopic.php?f=3&t=5620)
Fix fullbrights turning black after "kill" command (bug introduced in 0.90.0).
Clear all fog values on map change to prevent colored fog carrying over to jam3_tronyn.bsp.
Allow loading saves with } character in quoted strings, fixes issue with retrojam1_skacky.bsp.
Fix viewmodel not lerping on extended-limit maps.
Fix crash on out-of-bounds skin number.
Performance:
Use multithreaded OpenGL on OS X for better performance.
New, faster mdl renderer using GLSL. Disable with "-noglslalias".
Visual improvements:
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".
Use high-quality water by default (r_oldwater 0).
Shadows use stencil buffer to avoid overlapping artifacts (from MarkV.)
r_noshadow_list cvar added (from MarkV.)
Interface improvements:
Support pausing demo playback with the "pause" command.
Autocompletion for "game", "record", "playdemo".
Experimental windowed fullscreen mode available with vid_desktopfullscreen 1 (only in SDL2 builds, takes effect upon entering fullscreen mode the next time.)
Silence "exceeded standard limit" messages unless developer cvar is
= 1.
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"
Code cleanup:
Clean up IDE project files to build on fresh systems.
Update 3rd-party libraries.
Changes in 0.90.0:
Fix issues on Windows systems with DPI scaling.
Unix/Mac user directories support. Disabled by default, 'make DO_USERDIRS=1' to enable it.
SDL2 support. Disabled by default, 'make USE_SDL2=1' to enable it.
Revised keyboard input code.
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"
Command line: "-game {quoth/hipnotic/rogue}" is now treated the same as -quoth, -hipnotic, or -rogue.
Console speed now resolution-independent.
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.
PF_VarString buffer bumped to 1024, avoids truncated centerprints from the 'In The Shadows' mod.
Support for opengl non-power-of-two-textures extension (disable with command line: "-notexturenpot".)
Support for OpenGL vertex buffer objects (VBO, OpenGL 1.5 or newer) for world and brush models (disable with command line: "-novbo".)
Antialiasing (FSAA) support (command line: -fsaa x, where x can be 0, 2, 4, 8).
Fence textures support.
Dynamic light speedup. Speedup loading of tga and pcx external images.
Brush model drawing speedup.
Support for BSP2 and 2PSB map formats.
Support for Opus, FLAC, and tracker music (S3M, IT, UMX, etc.), as compile-time options.
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.
Better Hor+ field of view (FOV) scaling behavior.
Better cross-map demo playback support.
Fix screenshots when screen width isn't a multiple of 4.
Fix a lighting glitch due to floating point precision.
Fix a looping sounds glitch.
Fix a vulnerability in file extension handling. Tighten path handling safety.
Initialize opengl with 24-bit depth buffer at 32 bpp.
Reset all models upon gamedir changes. (Fixes failures with mods using custom content.)
Fix broken behavior upon gamedir changes if -basedir is specified on the command line.
NET_MAXMESSAGE and MAX_MSGLEN limits bumped to 64000.
MAX_EFRAGS bumped to 4096, and MAX_CHANNELS to 1024.
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.
Fix cvar cycle command not working sometimes.
Host_Error upon missing models. (Prevents segmentation faults.)
Change sv_aim default value to 1 (i.e. turn off autoaim)
Add 'prev' and 'next' keywords to the 'cd' command.
Work around a linux cdrom issue (playback might not start for a while after a stop).
Quakespasm content customization moved from engine-embedded into a new optional quakespasm.pak file.
Version bumped to 0.90.0 (because Quakespasm has a decent life of it's own)
Other fixes and clean-ups.
Changes in 0.85.9:
Fixes for several undefined behaviors in C code (gcc-4.8 support.)
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.
Adjusted string buffers for PR_ValueString and friends to fix crashes with excessively long global strings seen in some rude mods.
Toned down warning messages from PF_VarString() a bit.
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.)
Fixes/cleanups in chat mode handling. Client no longer gets stuck in chat mode upon disconnect.
Mouse grab/key_dest fixes and key cleanups.
The "speedkey" now acts as "slowkey" when "always run" is on.
Support for demo recording after connection to server. (thanks to Baker for a patch)
Corner case fixes in COM_Parse() for quoted strings and support for C-style /../ comments.
Changed lightmaps to GL_RGBA instead of GL_RGB.
Better parse for opengl extensions list (from quakeforge.)
Vsync saving/loading fixes.
Fixed pointfile loading.
Multiple cleanups in gl_vidsdl.c.
Opus music decoding support (as an optional patch only.)
Several other minor fixes/cleanups.
Changes in 0.85.8:
