I have been working very hard on another remake of the Wolfenstein 3-D engine, this time not only with the shareware but also with support for commercial Wolfenstein 3-D, Spear of Destiny, the Nocturnal Missions and even Super 3D Noah's Ark. Plus mods of all of the above. As a native Quest app AND for PC.
I started it in August 2019 and I expect it to be finished sometime this year. (in 2021)
