The new version of X-Sim has a Rock n Ride Virtual model to test the Simulators, using 2DOF.
Here some test with Freespace, at the momment i´m using only the 2 common Axes of the Joystick, X-Y
Speed, Z rotation, Force Feedback effects and others can be used as well.
With the free version, the OpenGL plugin extractor and other features are disable, but i want to investigate how it works.
If i remember well the price of the Standalone version with offline method and all plugins support is 60$.
The old test ...
The DirectX and OpenGL extractor
