Hi Folks! I've written some SDL units for GPC. They are quite incomplete but usable (as far as you only need video output). "Simple DirectMedia Layer is a cross-platform multimedia library designed to provide fast access to the graphics framebuffer and audio device." See http://www.libsdl.org for more details. Furthermore, SDL_gfx is included in the package, just to have some graphics primitives. You'll find the unit at http://www.gnu-pascal.de/contrib/eike/ (sdlgpc-date.tar.gz) Have fun. Eike
