--- Comment #10 from Jesse Allen the3dfxdude@gmail.com 2009-11-15 11:31:56 --- There are demos to the game but I wouldn't recommend those, as they will produce a black screen for two another reasons (one bug 18285). I committed two fixes to the game that will fix these: http://www.7kfans.com/git/?p=7kaa.git;a=commit;h=4c6872ae6133279b470404b9711... http://www.7kfans.com/git/?p=7kaa.git;a=commit;h=51b49fe1b91b549efd4365ed9d5...
This black screen however, seems to be caused by OpenGL interaction. You can obtain the actual GPL game at https://sourceforge.net/projects/skfans/
