I just downloaded the latest version of this demo and all I got was the HUD Lifebar and a message in big red letters "wide screen coming soon adjust settings in video option".
I tried doing just that, but nothing seems to change. I'm not quite sure if it's something I'm doing wrong or what. Frankly, I'm feeling a little lost in all this.
Anyway, I have openBOR 3.0 build 2123, if that's any help.
Just use the build (openbor version) inside the package
