@darkrom666: Dink Smallwood makes extensive use of Windows specific APIs, making it difficult to port to any platform.
@SnoopKatt: the source code is Turbo Pascal, it would need to be all translated to C++. In other words: no chance.
@bluewish: VDrift seems plausible. However, the XBox game library is already loaded with 3D driving/racing simulations which most probably make much better use of the specific XBox hardware, so I don't think anyone will find it useful to port thisparticular open source project.
