Bos Wars requires SDL 1.2. I patched it a bit and got it to build with SDL 1.3 SVN r5558, but there are problems. One of them happens in boswars/engine/video/sdl.cpp (InitVideoSdl):

TheScreen = SDL_SetVideoMode(Video.Width, Video.Height, Video.Depth, flags);
if (TheScreen && (TheScreen->format->BitsPerPixel != 16 &&
TheScreen->format->BitsPerPixel != 32)) {
// Only support 16 and 32 bpp, default to 16
TheScreen = SDL_SetVideoMode(Video.Width, Video.Height, 16, flags);
}

This is supposed to get a video mode with 16 or 32 bpp. However, what happens is the first SDL_SetVideoMode call returns a surface with 24 bpp, and when Bos Wars tries to change it to 16 bpp, the second call again returns 24 bpp! If I run Bos Wars with -D 16 or -D 32, so that the bpp in the first SDL_SetVideoMode call is 16 or 32 rather than 0, then it returns a surface with the correct bpp.

The bug seems to be that SDL_SetVideoMode first tries SDL_ResizeVideoMode and passes the bpp parameter to that, but SDL_ResizeVideoMode totally ignores the parameter.
