You must have 3D hardware, with a working OpenGL driver (e.g. Mesa, NVidia's proprietary driver, etc). You must also have SDL installed (http://www.libsdl.org) to run the "soulride" executable, although the "soulride-static" executable does not require SDL to be installed. The executables "soulride" and "soulride-static" are the same, except that "soulride" is dynamically linked against SDL, SDL_mixer and the C++ standard library, while "soulride-static" is statically linked against those libraries. Try "soulride" first, and if that doesn't work, try again with "soulride-static". Command-line options: Syntax: "soulride option1=value1 option2=value2 ..." * Fullscreen -- 0 for windowed, 1 for fullscreen * DefaultMountain -- give the name of the mountain, e.g. "Jay_Peak", "Breckenridge", "Stratton". These names come from the directory name under data/ where the mountain-specific data files are stored. * OGLModeIndex -- these are the options: 0: 320, 240, 16 1: 640, 480, 16 2: 800, 600, 16 3: 1024, 768, 16 4: 1280, 1024, 16 5: 320, 240, 32 6: 640, 480, 32 7: 800, 600, 32 8: 1024, 768, 32 9: 1280, 1024, 32 Thanks to the following people for Linux advice or assistance with testing on Linux: Andreas Umbach Sean Middleditch Ruediger Arp Chunky Kibbles hursh zakk
