I own both Gog's Incubation, plus I have it on disk. I had trouble with the gog installation because I have Windows 10. Installed it on disk and no problems, except no 3dfx mode.

So is there anyway I can import Gog's 3dfx files into my incubation folder and run it in 3dfx. Don't know if anybody attempted this, but if you did, let me know how.
It works-just copied the glide, 3dfx, and nglide application over into the incubation file and changed the resolution in nglide ap to 1080
