Grand news, and thanks a lot for pointing this out - Zork: Nemesis and Zork: Grand Inquisitor are now finally playable using these two options opengl/readdraw. There is a small glitch with screen redrawing, but hey - it works after YEARS!

If you are interested in using DirectDrawRenderer=opengl also make sure to play with the RenderTargetLockMode (default=readdraw). In case of Tiberian Sun 'readtex' is a lot faster.
