You may want to check out if older (pre-2.55.x) versions of dgVoodoo works. Btw, Intel HD 2000/4000 were mostly tested with Glide because the DX part of dgVoodoo did not exist at the time. So, that's why I'm not a big fan of having the newest drivers for old GPU's. Later I experienced broken things with newer drivers even with my NV GF 450 GTS. I emphasize "contemporary" because newer drivers interestingly removed FL 10.1 support. I started developing dgVoodoo on a HD 2000 with feature level 10.1 (2012) and things worked with a contemporary driver. Yes, I mentioned Intel HD 20 amongst the tested GPU's. It's Gen9 and this is the oldest Intel I have these days. DX11 FL 10.0 is still supported in dgVoodoo, I just ran 3DMark2000/2001 through that on my Intel HD Graphics 505. TBH, dgVoodoo should work on those chipsets.

Thanks for this extensive, well-illustrated report!
