[azotyp]

So I found homebrew called dsdsrevolution, it is rythm game homebrew that uses songs from stepmania,
but when I tried to open that homebrewe game it says
Sm filp not found (12)
Can someone help me with this, what I must do to make it work (I have one of songs from stepmania in songs folder).
