I've noticed that I can open my FamiTracker 0.3.0 files in FamiTracker 0.3.5 & they play/export as they should. But if I open a FamiTracker 0.3.5 file in 0.3.0, the track opens properly, but the instrument settings aren't honored (even though volume & duty settings may be check-marked, the settings & MML values themselves are wiped out).
