the group who released these was B.N.K. and they were based in Germany....
B.N.K - I remember that from the opening screen! I don't recall ever seeing anything else by them though. I had the vague impression it was just one guy, no idea why! Also, for a disk produced by "scenesters" there was nothing to point to their BBSs or a 'Greetz' list or anything (that I recall)... It all added to the mystery!
