ok, I was looking on the internet today, and FINALLY found the adapter for PS controller to XBOX360. I read a review about it, nothing bad (except for the price).
I am supposing many of you wanted to find the adapter since you wanted to use your metal dance pads.
SO here is the link to the review and places yo buy...
MAXCONSOLE - Playstation 2 Playstation 3 Xbox 360 Nintendo DS PSP Gamecube Nintendo WII Revolution - To the MAX!
I would like to point out you will need a wired 360 controller to make this work, and you will need to program the buttons yourself.
I myself wont get one, but only because $80 (well now its $50) was just as much as the game and dance pad, to which i already own.
Sorry if someone posted anything like this before me.
