With permission, I uploaded the official, and several of the unofficial, patches to Nexus Mods if anyone needs them. I also uploaded some small patches I use to re-enable the dummied-out techs and unit abilities, restore some intended effects, and some other things.
Unfortunately, GOG is blocking me from posting the direct links - guess I'm not on here enough. Go to NexusMods.com, search for Sid Meier's Alpha Centauri, and you'll find both the official and unofficial patches - Nathan Baggs' Windows 11 patch, the Scient patch, a couple I created, etc. The GOG version already has all official patches; I notified GOG's technical team about the Nathan Baggs patch and the muted sound effects issue, and they responded positively, so hopefully those will be fixed in a future release on GOG.
The unofficial patches include some optional files that re-enable Inertial Damping, Global Energy Theory, Heavy Transport, a nerve pod missile unit, and some other things that were dummied out by Firaxis but remain functional.
Also, while alphacentauri2.info is gone, it was recreated at alphacentauri2.com.
