What DDR games exist for the Wii U?  I know there's 2 games for the Wii, at which point the question is how did you play the Wii games previously?   Or are these newly acquired Wii games for the Wii U?

I really, really doubt any of us have tried to convert from PS2 to Wii here, but maybe someone has!  The Wii U isn't really the "music gamer's console" when compared to say the PS3 or PS2 even still.

Five DDR games on the Wii, zero on the Wii U. I use a PS2 to Gamecube adapter to connect my PS2 pads to the Gamecube ports on the Wii to play the Wii games. I don't own a Wii U, though, so I can't help you there.

Wii's are also available (used) for ~$35 on Craigslist. I would say it might just be easier to but one of those instead of hassling with getting it to work on the Wii U.

It would be using Wii games on the Wii U, we just ditched our Wii when the U came out. Good to know they can be used on the Wii with the GameCube converter, guessing I'll hope for the best and try it out. Thanks for the help.

The official GameCube adapter for the Wii U won't do anything outside of Smash. So don't bother with it.

I believe all of the Wii DDR games supported the Classic Controller, so if you had some sort of way to plug them in that way, you could possibly play them on the Wii U. I have not actually tested this myself (don't have a GC>Classic converter), so I can't say if it would actually work, and not do something like prevent up+down or left+right presses.
