I promised you reporting the results, so (it's not a full test-list yet but only a short reply):
Again, thanks for the extensive list!!
Some other 3dfx tech demos
http://www.falconfly.de/artwork.htm [(All seem to work fine)
60Hz/30Hz/15Hz [Windows-Glide] (Works fine)
ATB TV [Windows-Glide] (? Uh, couldn't identify this one at the moment)
BorgCube [Windows-Glide] (Works fine)
DemoRoom [Windows-Glide] (Works fine)
Donut [Windows-Glide] (Works fine, glide2/3)
Race [Windows-Glide] (Works fine)
Surf [Windows-Glide] (Works fine (glide 2/3), altough no specular highlight with glide3 napalm, will be investigated)
Grand Bleu [Windows-Glide] (Works fine)
Valley of Ra [Windows-Glide] (Works fine)
Wizard Tower [Windows-Glide] (Works fine)
ATB Minigl demos [Windows-Glide] (Should try it, don't know yet)
T-Buffer/KittyHawk/Museum/RocketBurger [Windows-Glide] [requires supporting some VSA-100 Glide3 extensions] (Works fine, but with some problem with Napalm: it can crash sometimes for some reasons; AA is ok, but I don't see any difference between spatial AA/no spatial AA)
To Be Continued... - by Saw Tooth Distortion (Windows): http://www.pouet.net/prod.php?which=18874 (need to grow the stack of TBC.exe to avoid crash, apart from that works fine)
Virhe - by maturefurk (Windows): http://www.pouet.net/prod.php?which=1084 (Works fine)
Trip - by KFMF (DOS): http://www.pouet.net/prod.php?which=2844 (Works fine apart from some DosBox performance glitch at a point. Also needs unforced vSync to play smoothly.)
Dimension by - gods (DOS): http://www.pouet.net/prod.php?which=2182 (Works fine but seem to quit to early. Missing files?)
Žertva - by C.P.U. & Musica Vitae (Windows): http://www.pouet.net/prod.php?which=24753 (Inner church rendering has some misrendered polygons. Must be a bug in Glide3, will be investigated, otherwise ok)
Scorpion - by Niels & MalcolmZ (Windows): http://pouet.net/prod.php?which=30133 (Works fine)
codename chinadoll - by katastro.fi (Windows): http://pouet.net/prod.php?which=119 (works fine, but this demo is very GPU-intensive for some mythical reasons)
shortcut - by buckshag (DOS): http://www.pouet.net/prod.php?which=17221 (Works, but there is a problem *)
Nature - by Vertigo (for DOS and Windows) - http://www.pouet.net/prod.php?which=2181 (Works, but there is a problem *)
* These demos stall at a point. This means rendering gets very very slow, almost down to zero speed, for example Nature's loader strip and fading screen at the beginning. This is because these demos drives the 3Dfx card at max speed in a crazy way and the emulation can't keep step. Back a few month ago I was pondering how to workaround these cases (since the vast majority of operations made on the 3Dfx card could be simply wasted) but found no way since then. Probably it would also be a problem on a real 3dfx card with a modern 3.2GHz CPU.
Either you sweat that 10 minutes (that needed to get over those renderings) out or try some tricking with pausing/unpausing DosBox if you want to see the demos. Apart from that, other parts works ok, but unforced vSync is need o play them smoothly.
And screensavers like:
Blob Cosmos (Windows) - http://www.3dfxzone.it/files?object=3dfx&objid=635 (Works fine)
VoodooLights/Cosmos (Windows) - http://www.3dfxzone.it/files?object=3dfx&objid=663 (Works fine)
And indie apps like:
3dxmrph (Windows?) - https://sourceforge.net/p/openglide/bugs/10/ (Works fine)
SceneTest (Windows) - http://www.mcmanis.com/chuck/3d/ (Can't remember if I was managed to get it to run)
Another odd thing I have is suprgrab, a 3dfx screenshot utility and snap3dfx, a frontend for it. However, it requires sst1init.dll and Glide 2.1.1.
http://www.vogonsdrivers.com/getfile.php?fileid=493 (Can't remember if I was managed to get it to run)
There is a lot to test:
