Here's a Savefile of the PAL version of DDR Winx Club, given someone DID requested for one in the forum. All it took was finishing the Lessons, play the Story mode with each girl and a few replaying and it was done.
-All the songs unlocked. Tracklist: http://www.youtube.com/watch?v=TjDlqjbtcXI
-All 3 costumes for all the characters.
-AND quite a few song scores of my own ;)
Just copy this from SD Card to Wii, and enjoy :)
