Alternate cdtitle - if you prefer the artist name for the CD title instead of the song source.
LRC files - Self explanatory.
BG2 - Background without the bevel effect.
olddwi, oldsm - I revised the single light and heavy charts from the version that was submitted to OSC5. These contain the originals - replace the current DWI and SM files with them (renamed, of course) if you'd rather play the original OSC5 steps.
