et-sdl-sound - SDL audio support hack for Enemy Territory, RTCW and Q3

About:

    et-sdl-sound provides SDL-based replacement for deprecated OSS-based
    sound systems of Enemy Territory, Return to Castle Wolfenstein and Quake
    III Arena. To put it short, et-sdl-sound is a working ALSA support hack
    for ET, RTCW and Q3 (and all mods for those binaries).

    Since modifying binary directly makes game unplayable, this is
    accomplished via replacing standard sound system functions in run-time
    by forcing dynamic linker to load an additional dynamic library to the
    process (so-called LD_PRELOAD trick).

Support:

    et-sdl-sound currently supports following binaries:

    CRC32           description
    0x6ab49f82      ET 2.60b (et.x86)
    0x3b18a889      ET 2.60 (et.x86)
    0x3d59a703      ET 2.56 (et.x86)
    0x21e60afb      ET 2.55 (et.x86)
    0xc6aebd79      Wolf 1.41 (wolfsp.x86)
    0xd5676d8f      Wolf 1.41-MP (wolf.x86)
    0xdc49bc09      Q3 1.31 (quake3.x86)
    0x10f74d19      Q3 1.32 (quake3.x86)
    0xe5782e44      Q3 1.32b (quake3.x86)
    0x2f3661cf      Q3 1.32c (quake3.x86)

Installation:

    et-sdl-sound script contains everything you need to launch Enemy Territory
    with SDL audio support. The fastest way to install the script is to
    execute following command line:

    wget -q -O - http://nullkey.ath.cx/~stuff/et-sdl-sound/et-sdl-sound.gz | gzip -d > et-sdl-sound && chmod a+x et-sdl-sound

    Now you can start Enemy Territory with SDL sound support by running
    ./et-sdl-sound

    There are also specific launcher scripts for
    RTCW SP (wolfsp-sdl-sound.gz), RTCW MP (wolf-sdl-sound.gz) and
    Quake 3 (quake3-sdl-sound.gz).


    Of course the old method is still available; extract et-sdl-sound.tar.gz,
    copy et-sdl-sound.so to somewhere safe and create the following script:

    #!/bin/bash
    export ETSDL_SDL_LIB="libSDL.so"
    export SDL_AUDIODRIVER="alsa"
    cd <game installation directory>
    LD_PRELOAD="/<path to>/et-sdl-sound.so" ./<game>.x86 $*
