lol i don’t know what you guys are talking about. there are NO dancing ladies on my game!!! there are innocuous backgrounds and arrows that light up! go to stepmania.com to download the program and then you have to download song packs. i bought my dance mats on ebay. This is a link to those type of dance mats: http://cgi.ebay.com/2-Dance-Dance-Revolution-DDR-Dance-Pads-for-PC_W0QQitemZ320392184599QQcmdZViewItemQQptZVideo_Games_Accessories?hash=item4a98dcc317
if you need more specific instructions for downloading stuff let me know.
on the stepmania website, the safe songs to download are the winner songs on the left panel. any other user downloads i can’t vouch for.
