Mine has all the functions, except for the three buttons on the left of the Lynx screen, so: ON, OFF, BACLIGHT which are unnecessary on an external controller.
While it has all the other functions, so if you press together OPTION1 and II on the controller, you will have RESTART. Also if you press II and OPTION2 together you will have the FLIP function, so the 90° rotate feature you were talking about. Even if this feature is unnecessary playing on a monitor....
The aesthetic result is good, in my opinion. Also for the connector on the Lynx...
