Edit: I just learned that a 2SF set for B2W2, not included in 2sf.joshw.info, also includes the downloadable musicals, so it must mean that yes, it must be possible for the original BW, too. I wonder if B2W2 will also receive the NCSF treatment.
Yes, B2W2 NCSF is possible, if you want just use 2SFtoNCSF with the tagged set I posted in that thread (it is part of the official NCSF toolkit) and you're set. Be careful though, for some reason "331 THE END.minincsf" refuses to play with the foobar2000 NCSF decoder.
