--- Comment #1 from Werner werner@armbian.de --- After some more testing I found out that it works nicely in playonlinux so either they have some special settings for this game to work or there is a regression in wine version >4.0.4 which is used there.
I used it to create myself a savegame immediately after the initial Underworld sequence has completed, copied it over to my wine installation, loaded and works fine.
