I take very little credit for this because I did very little here. Downloaded the 2SF set and the latest version of the plugin to play them (http://www.zophar.net/music/2sf.html) and converted to FLAC with foobar2000. So this isn't a rip directly from DS hardware, but it sounds better. I turned cosine interpolation on, which makes it sound significantly cleaner and clearer than on an actual DS. It sounds better than the officially released version in some ways too, in others that one's better. This sounds overall better to my ears, but compare and contrast if you like.

I also included the MP3 from Galbadia Hotel of the first track from the official version because on the DS it's streamed with a lower sampling rate and has more clipped peaks.
