Yes, but some games like SFA2 you have to switch the pad to digital mode, another thing I noticed was how the 3D pad had the most awesome d-pad ever, it tops the Genesis pad and Saturn (JP). Makes you wonder how they went from the very best to very worse with the d-pad on the DC controller. The buttons on the 3D controller are also better than the digital Saturn pad because they are all of the same size.
Tried Soviet Strike, although the game has very impressive FMV the game itself is a load of crap, it runs at like 16FPS and it still has major slowdowns, the controls are ok but the frame rate ruins everything.
So far only NiGHTS seems worth of getting a 3D pad, once you memorize the stages you can do a lot with NiGTHS, quite the acrobat 🙂
