Here you can find links to several complete game demos, complete with source code.

Novint Falcon Sandbox Driving Demo
This demo was built in 3D Game Studio, with a C++ module to run the Novint Falcon haptic controller.

Nintendo Game Boy Advance Home-Brew Games
This page includes source code for two home-brew GBA games I built in C.

Unity3D Home-Brew Development
I've recently started learning the Unity3D Game Engine and the C# coding language. Here you can follow my progress building a simple game in Unity. There are no code samples yet (since this is a testbed for training myself), but you can play what I've built so far in a web browser.

To learn more about the games I've worked on, go to my Games Page.
