What a pain...
Found that these titles are indeed very picky. Best I got running natively was running them with PC-speaker for audio. All seem to need EMS and that only seems to work if I manually enter the settings on the executable's shortcut. No AdLib, SB, or Roland and no VDMSound.
Willy seems to run on DosBox, but the other two gave me unsupported errors (odd since they are 286 or earlier). You may have to wait for DosBox .60 or higher for these.
If all else fails, there are Amiga and Mac versions of all three. Of course the Amiga version has less color (but usually good audio), and the Mac has the 1-button mouse control and some sound latency issues on Basilisk.
