Which is exactly why I'm fearing vWii will never support this feature and Nintendo wants us to pay the fee to "upgrade" our games for the better experience with Wii eShop downloads, much like Virtual Console titles bought on Wii had to be upgraded against a fee to the Wii U versions for enhanced features.If there was no update then I guess all the magic is happening with the digital download itself which probably mean it will not be a system wide feature.
Currently this doesn't work of course as Nintendo hasn't pushed out an update to add support. Though when Punch-Out!! comes out on the eShop we'll know for sure.The way to test it is put a Wii disc in that supports the classic controller.
