In Gecko OS I can load my custom menus just fine.  However in Riivolution, it does not load them at all.  Is this normal?

In Gecko OS, my custom soundtrack's custom titles show up just fine.  However in Riivolution they do not show up at all.

In Gecko OS, is there a file size limit?  Because I put up a bunch of songs on my SD card (around 18 songs) and the game freezes after the loading screen.  However Riivolution loads just fine (I know this has an unlimited file size).  I even deleted almost all my textures, and it still didn't work.  

P.S. I use Brawl with Codes in Riivolution, because I honestly don't know the difference between Brawl +/- etc.

So no matter what I do, how hard I try, the import stages I get are always pitch black with just one item showing up (an item that is in the original level, but not the imported stage)

I've gotten Riivolution and looked at multiple guides... yet still, this stage just doesn't want to change.  Help pl0x?
