Do you use Gog Galaxy?
Nope, and for an old game like this one, I don't recommend you to use GOG Galaxy. What I recommend you to do is to uninstall the game via GOG Galaxy, then install the game using a tool called GOG Downloader: https://www.gog.com/downloader
Once downloaded, sign into the application and have it running. Now go to your games library, select Homeworld Emergence, but click the More drop down and then GOG Downloader Links. The link at the top is the one to select, it will download a simpler installation file via the GOG Downloader. Once downloaded, run the installer, tweak any options and the game should run better.
Then, follow the instructions of my previous post (run game as admin, change to OpenGL from 3dfx OpenGL option and so on) :)
As for the screenshot, your crash will this time be caused by the fact you have the wrong "glToSelect" that does not match the deviceIndex (Index 1 = OpenGL). As suggested, change the glToSelect to just "opengl32.dll", but I'd still recommend reinstalling the game using GOG Downloader for compatibility. :)
