I just checked their forums and it's a feature they're apparently working on for a near future release. Yay! :-)
If ANYBODY has found ANYTHING about a positive result that would be amazing I just used the DLC wads for GB2/3 and GH5/World Tour. Unfortunately I have NOWHERE to store any of the songs since the SD will not be recognized. Any information would be useful. The ladyfriend is counting on me. Thanks guys!
