1. About
QuakeSpasm <http://quakespasm.sourceforge.net> is a Quake 1 engine
based on the SDL port of FitzQuake
<http://www.celephais.net/fitzquake>.
It includes support for 64 bit CPUs and custom music playback, and
includes a new sound driver, some graphical niceities, and numerous
bug-fixes and other improvements.
2. Downloads
o Project Downloads: http://quakespasm.sourceforge.net/download.htm
o Automatic Builds: http://quakespasm.ericwa.com/job/quakespasm-sdl2/
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 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.
4. Compiling and Installation
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.
To checkout the latest version of QuakeSpasm, do:
svn co svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm
4.1. Linux/Unix
After extracting the source tarball, browse the Makefile and edit the
music streaming options, then
______________________________________________________________________
make
cp quakespasm /usr/local/games/quake (for example)
______________________________________________________________________
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
Streaming music playback requires "libmad" or "libmpg123" for MP3, and
"libogg" and "libvorbis" for OGG files.
The project can also be built with Codeblocks (project files
included).
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.
5. Known Bugs
Brightness issues should be fixed with GLSL gamma in 0.90.1, if your
system supports OpenGL 2. For reference on older systems:
Some versions of Xorg and SDL have brightness issues.
Try setting "export SDL_VIDEO_X11_NODIRECTCOLOR=1", or if you have
Xorg >= 7.5 and broken brightness, these patched libSDL binaries may
help.
o Gamma patched libSDL (i686-linux)
http://sourceforge.net/projects/quakespasm/files/Support%20Files/libSDL_gamma_patched.tgz/download
o Gamma patched libSDL (x86_64-linux)
http://sourceforge.net/projects/quakespasm/files/Support%20Files/libSDL_gamma_patched-AMD64.tgz/download
The "game" command doesn't execute quake.rc in the new game directory
being switched to. This means any custom key bindings in a mod's
config.cfg or special settings in a quake.rc won't be loaded. The only
workaround is launching the engine with the -game command-line switch
instead of using the game console command. Or, after running the game
command, you can run "exec quake.rc" by yourself (YMMV).
6. Changes
6.1. Changes in 0.91.1
6.2. Changes in 0.91.0
6.2.1. 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

6.2.2. 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.
6.2.3. Interface improvements

frame late (bug introduced in 0.90.0).
o Fix texture memory leak when changing video modes with SDL2.
o Fix rare incorrect mdl lighting on 64-bit builds. (details here:

o Allow loading saves with } character in quoted strings, fixes issue
with retrojam1_skacky.bsp.
o Fix viewmodel not lerping on extended-limit maps.
o Fix crash on out-of-bounds skin number.
6.3.2. Performance
o Use multithreaded OpenGL on OS X for better performance.
o New, faster mdl renderer using GLSL. Disable with "-noglslalias".
6.3.3. 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.)
6.3.4. Interface improvements
o Support pausing demo playback with the "pause" command.
o Autocompletion for "game", "record", "playdemo".

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",

"PR_AlocStringSlots: realloc'ing"
6.3.5. Code cleanup
o Clean up IDE project files to build on fresh systems.
o Update 3rd-party libraries.
6.4. Changes in 0.90.0
o Fix issues on Windows systems with DPI scaling.
o Unix/Mac user directories support. Disabled by default,
'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
with command line: "-notexturenpot".)
o Support for OpenGL vertex buffer objects (VBO, OpenGL 1.5 or newer)
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.
o Fix screenshots when screen width isn't a multiple of 4.
o Fix a lighting glitch due to floating point precision.
o Fix a looping sounds glitch.
o Fix a vulnerability in file extension handling. Tighten path
handling safety.
o Initialize opengl with 24-bit depth buffer at 32 bpp.
o Reset all models upon gamedir changes. (Fixes failures with mods
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.
6.5. 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.
o Support for demo recording after connection to server. (thanks to
Baker for a patch)
o Corner case fixes in COM_Parse() for quoted strings and support for
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 increased (more than 32) dynamic lights.
o Music playback: Made sure that the file's channels count is
supported.
o Support for Solaris.
o Switched to using libmad instead of libmpg123 for MP3 playback on
Mac OS X.
o Better support for building the Mac OS X version using a makefile,
support for cross-compiling on Linux.
o Fixed a minor intermissions glitch.
o Increased string buffer size from 256 to 384 for PF_VarString to
work around broken mods such as UQC.
o Restored original behavior for Quake registered version detection.
o Minor demo recording/playback tweaks.
o Minor tweaks to the scale menu option.
