<H2><A NAME="s1">1.</A> <A HREF="#toc1">About </A></H2>
<P>
<A HREF="http://quakespasm.sourceforge.net">QuakeSpasm</A>
is a modern, cross-platform Quake engine based on
<A HREF="http://www.celephais.net/fitzquake">FitzQuake</A>.</P>
<P>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.</P>
<P>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.</P>

<P><EM>Visit the
<A HREF="http://www.celephais.net/fitzquake">FitzQuake homepage</A> for a full run-down of the engine's commands and variables.</EM>
<UL>
<LI>To disable some changes, use "<B>quakespasm -fitz</B>"</LI>
<LI>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.</LI>
<LI>For different sound backend drivers use :<BR>
"<B>SDL_AUDIODRIVER=</B><EM>DRIVER</EM><B> ./quakespasm</B>"<BR>
where DRIVER may be alsa, dsp, pulse, esd ...</LI>
<LI><B>Shift+Escape</B> draws the Console.</LI>
<LI>From the console, use <B>UP</B> to browse the command line history and
<B>TAB</B> to autocomplete command and map names.</LI>
<LI>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..</LI>
<LI>In windows, alternative CD drives are accessible by<BR>
"<B>quakespasm -cddev F</B>" (for example)</LI>
<LI>Quakespasm allows loading new games (mods) on the fly with<BR>
"<B>game</B> <EM>GAMENAME {-quoth/hipnotic/rogue}</EM>"</LI>
<LI>Use "<B>quakespasm -condebug</B>" to save console log to "qconsole.log". SDL2 builds no longer generate stdout.txt/stderr.txt.</LI>
</UL>
</P>
<H2><A NAME="ss3.1">3.1</A> <A HREF="#toc3.1">Music Playback</A>
</H2>
<P>Quakespasm can play various external music formats, including MP3, OGG and FLAC.
<UL>
<LI>Tracks should be named like "track02.ogg", "track03.ogg" ... (there is no track01) and placed into "Quake/id1/music".</LI>
<LI>Unix users may need some extra libraries installed: "libmad" or "libmpg123" for MP3, and "libogg" and "libvorbis" for OGG.</LI>
<LI>As of 0.90.0, music is played back at 44100 Hz by default with no need to adjust "-sndspeed".</LI>
<LI>Use the "-noextmusic" option to disable this feature.</LI>
<LI>See
<A HREF="Quakespasm-Music.txt">Quakespasm-Music.txt</A> for more details.</LI>
</UL>
</P>
<H2><A NAME="ss3.2">3.2</A> <A HREF="#toc3.2">Controller Support</A>
</H2>
<P>The SDL2 variant of Quakespasm supports Xbox 360 style game controllers.</P>
<P>The default configuration uses the left analog stick for movement and the right for looking.</P>
<P>If your controller doesn't work you can try placing
<A HREF="https://raw.githubusercontent.com/gabomdq/SDL_GameControllerDB/master/gamecontrollerdb.txt">this file</A> in your Quake directory, it is a community-maintained database that adds support for more controllers to SDL2.</P>
<H3>Cvars</H3>
<P>
<UL>
<LI>joy_deadzone - Fraction of the stick travel to be deadzone, between 0 and 1. Default 0.175.</LI>
<LI>joy_deadzone_trigger - Fraction of trigger range required to register a button press on the analog triggers, between 0 and 1. Default 0.2.</LI>
<LI>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).</LI>
<LI>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.</LI>
<LI>joy_invert - Set to 1 to invert the vertical axis of the look stick.</LI>
<LI>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.</LI>
<LI>joy_enable - Set to 0 to disable controller support. Default 1.</LI>
