well of course it does, it's how it was made, i finished the game fine with those controls some 28-29 years ago. If i want to play it again i do want the best experience though, and mouselook would certainly make the controls somewhat better. I see now that there's no UW2.exe to patch with GoG release. Odd...
If it's the same version I have, the one which includes both UUW games, the exe files are actually inside "game.gog", which is an iso file with a different extension. Once you run the game via the icon it places on your desktop, it just somehow looks in there for the necessary files.
Which is a bit of a pain in the ass if you're trying to apply some patch or hack to the exe. What you must do is this:
- rename "game.gog" to "game.iso"
- open up iso file, extract the contents into some directory
- patch the exe file(s)
- create a new iso file, also named "game.iso", with the contents of the directory (now patched)
- rename it "game.gog"
- replace original game.gog with the new one (back up the original one first)
Now you should be able to click on the dektop icon for the game and have it work
with the changes.
