Add opl3gold option to oplmode setting. With this option the AdLib Gold
music can be selected in Dune. Only FM music without effects (reverb,
stereo enhancement, surround sound, etc.) is supported. FM volume
control, used in the CD-ROm version of Dune, does work.
the difference between the existing WAV recording mode and multitrack
recording is that all mixer channels are recorded separately to their
own audio track in an AVI. Hopefully, you can use the AVI to then do
your own downmix in your video editing software of choice.
