I have a few songs that will show their Bn/Bg, and I myself have been trying to get to the bottom of why and how I can get them to display. I'm told by the Arcade Op. that it's the machine just not loading it, and it occasionally will load them, which makes a bit of sense because the machine will choke on songs once you have between 40-50 songs on a USB drive on occasion. What doesn't make much sense to me is that these files recognize the banner and background in ITG2 for the PC, and stepmania. It does say though that the arcade isn't supposed to load them...
Regardless, every file I have is .sm with .ogg music (of course), and all of the image files are .png and refered to in the exact same way in the .sm file.
