I GOT IT TO WORK!!!
and on 1920 x 1080!!!
I read a solution from
https://www.bleepingcomputer.com/forums/t/684145/star-trek-starfleet-command-3/I took the posters advice.
Installed a clean, unpatched SFC3
On every step - I tried the game to see what happens, and if it didn't work - I'd add another fix
So, after installing a clean, unpatched version - I copied the Modelrender file from the components file.
Patched the game to 534b, then replaced the patched ModelRenderer with the unpatched version - results were still a blank screen w/sound
Then I added the .dll files from DGVoodoo (both the MS and the 3dx files) and the program itself - still a blank screen
Then added the HD Patch (replaced assets/sprites) SFC.ini and the SFC.exe
I changed the SFC.ini according to the post:
width=1920
height=1080
BlueLight=1
wireframe=0
windowed=1
When I started it, I received an exception error regarding the ModelRenderer.
So I put the patched version back...and started the game.
AND IT ACTUALLY WORKED!! IN FULL SCREEN, TOO!
I've only tested the single player skirmish and I thought it would crash when I changed to different ships.
I had the loading screen stuck a third of the way with a blue windows circle spinning. I was ready to end the program, when it started!
Now, I'm thinking about unchecking the DGVoodoo watermark...but I'm afraid it'll mess things up.
I hope this helps anyone else trying to get this game to work on windows 10.
Oh...I'm running the .exe with No Compatibility, 16 colors, and as admin...if that helps.
