A couple of things you need to know if you're interested in it. It's from the year 2001, and I had been programming for about three years at the time. So it's not pretty. I'm not going to help you understand the code, but if you make a new version, I'd be happy to distribute it. You'll need DirectX SDK 8 to compile it. I used Visual Studio 2008, I guess it needs a few changes to work on any other compilers.
You're allowed to do anything you want with this. Including the sources, pictures, 3D models and sounds. Start selling it if you want to. If you get famous because of this, you have to say it's all thanks to me.
