Some people here might be interested in the VGM log of Dune Sega CD. The YM2612 soundtrack sounds quite similar to the AdLib (YM3812) version, although it lacks a channel or two. If the FED2k admins are willing to host the package in their Downloads section, they're more than welcome. Dune Sega CD
Is there any way of playing back the AdLib Gold version of those tunes on our modern systems? DOSBox emulates an OPL3/SB16, but not the AdLib Gold. Thus Dune can only be configured in standard AdLib/SB mode, which is a huge shame. I may be wrong, but I think AdPlug doesn't support the AdLib Gold either -- at least the AGD format is not recognised by AdPlug 2.0.
