Does the Doom demo actually work? That'd be enough for me to call it "not vaporware" by a longshot.
IIUC they use chocolate-doom that has approximately 600 .c files, and replace one of them with a .v file. I don't understand what they mean when they say
> DOOM translated from C to V. Builds in 0.7 seconds (x25 speed-up).
The magic porting of C-Doom to V-Doom is still WIP
Aha, I took their marketing at face value. I never learn... :(
