Well, did all you said and------- guess what it did not work!!
It still wants both of the 2 folders for Sapphire and Titania.
Gld and Ultima, Techno and Trinity all work fine with just the inside folder in the plug ins.
BUT not these 2.
And I think Volume Control was the same. Since I loaded it I have no music or game sounds at all, so I have pulled it out. Hope to get ome sound now!!!
Sorry your idea did not work!
However I am happy playing as it is!
