Wii U Stick Compatibility

I'm aware that MadCatz released a Wii U Arcade stick for the release of Tag Tournament 2. It supposedly functions like the Tatsunoko Vs Capcom stick for the Wii, in that it has a cable that connects to the Wii remote like a classic controller. My question is: Is the Wii U Arcade Stick compatible with Wii Games, like SNK Arcade Classics Vol. 1, TvC, The Samurai Shodown Anthology, etc.?

I'm just asking anyone who owns the stick to try it out on any Wii games that they own to see if it works.
