Are you on Windows? If yes, get in_vgm and use some Winamp WAV writing plugin for that job.
i'm aware of that, unfortunately i don't have Windows anymore - i used to keep one for such occasions but it had the tendency to die out of blue all by itself, all the time, requiring formats & reinstalls more often of than i deemed worthy, so the last time few years back it wouldn't boot i decided to let the poor thing go

it seems AO doesn't let you start exporting WAVs from NSF files that are not the first track - "Jump to" does show you "L" but doesn't actually export anything and clicking "Next" while recording keeps "L" but stops the WAV
