Just Dance 4 and DLC

[netsonic]

I try to play just dance 4 dlc gangnam style with dolphin. It seems to be impossible. I have got the SD card content of the DLC(which contains three bin files(privae\wii\DATA\sJXE\000.bin,001.bin,007.bin) ). I use winimage to add the directory and file to the root of sd.raw sucessfully, but when in game, I have ticked insert SD card before, there is nothing on SD card. Could someone tell me how to add files to SD.raw correctly, and Is it possible to play dlc gangnam style with dolphin?
