MadHatter at the BS Zelda forums linked me this the other day;
A profile for “St.GIGA” at last.fm
I don’t really know how this site works, but I have checked out the various listings. In particular, the “tracks” listing has an entry for “BS Tantei Club ending theme”. Hmm…!
There is also a “St.GIGA Radio” option. The musical selection in this is a very bizarre mixed lot of Middle Eastern, Americana, and Japanese.
If this is the same St.GIGA from the old times, I wonder if this would mean well for the archival of Satellaview data…
