So my parents just bought a Wii

and I have a dance pad thats made to work with a playstation 2

so my first question is:

Do the Wii dancing games require a regular dance pad? or is it some strange wii shit?

and if it takes a dance pad, can i buy an adaptor from ps2 to wii?

If the dance pad is USB, it should work. Test it out.

Well no the dance pad is for ps2 which means its a ps2 jack

although I have a ps2 to USB converter, it doesnt recognize multiple key presses simultaneously... that could be a problem
