I would say that it count as Wii VC, but do you see a "A classic controller is required blablabla" when you launch and reset the game ? If so, it would count as a Wii VC, but if not.. I would not know what to say, someone else would have to say something :P

I've added Wii U VC now. You can select to go under the "Wii VC" category but then select Wii U VC as the actual platform. (Sorry I took a while to respond.. I never look here because nobody ever posts lol)
