The graphics config: no HQ scaling enabled. You need to enabled "ddraw" scaling (output=overlay), "hq3x" (scaler=normal2x) and your favorite resolution manually in the Dosbox config file.
Go to Your "UNDEROM1\DATA" folder, and open up the UW.CFG, and edit the first line:
from "6 -1 -1 -1 sound",
to "4 -1 -1 -1 sound".
I'd recommend changing the sbtype in the [sblaster] section of their DOSBox CONF files from sbpro2 to sb16
