Moto Trial Racer XNA is a motorcycle racing game on Windows Phone 7 and XNA Game Studio 4.0, demonstrating especially the use of Box2D.XNA, an XNA binding for the Box2D physics engine.
This application has been ported from a corresponding Qt Quick example, and thereby also demonstrates and provides guidance on the porting and co-development between Qt and Windows Phone. The application's graphics have been reused from the QML version. This example is hosted in a Nokia Developer Project, where you can find implementation and porting notes, discover recent revisions, and contribute to the project.
