hi. this is invaders, a multi boot compliant game for i386. boot it with grub (http://www.gnu.org/software/grub/) like this: menuentry "Grub Invaders" { multiboot /boot/invaders boot } run the compile.sh script to compile the game, or just use the precompiled image. (do not try to boot "invaders.exec", that's the wrong file. use "invaders" instead) the license of the whole project is the GNU General Public License, see the LICENSE file for details. have fun, Erik erikyyy@erikyyy.de
