Every Classic Controller game is compatible with it. And you can use it on PC (Glovepie is your friend) also.

I play with this stick during gamescom of cologne and you can be sure what it was really extremely fun !!! Like a true arcade game !

And we know already what Capcom will be able to produce tatsunoko VS capcom 2.
Niitsuma San said that during the interview (see the link in the subject)....if Tatsunoko 1 make good sell...

Interested Link to Amazon, where we can see the cost of Tatsunoko VS Capcom.

It's 60 euros. Very strange, cause, usually (but perhaps a mistake of mine?) capcom games cost 40-50 euros on Wii. You can have the darkside for 40 euros and Darkside + zapper for 50 euros...
Spyborgs : 40 euros
So, it could be possible to have a special bundle of tatsunoko + Arcade stick for 60 euros ???
40 euros for tatsu and 20 euros for arcade stick.

Feel good...
