All patches were available at http://alphacentauri2.info/
With AC2 down, this page was last updated with a link to Thinker mod and DOS days mirror on November 25, 2024, prior update October 31 2022. Smac-in-smacx allows you to use mods and unofficial patches made for the stand-alone expansion in a game largely akin to the original. Scient's unofficial patch for the expansion only did bug fixing for the expansion if you want nothing else. I personally think you are missing out if you never try AI improvement mods.

https://github.com/DrazharLn/scient-unofficial-smacx-patch/releases/download/v2.1/SMACX_UP_v2.1_Installer.exe

The GOG download is already updated to the latest official patch, including the SMAC Win 2000/XP Update. Many unofficial patches were just executables that can be applied directly, making a backup of the EXE. This is not the case for Yitzi, who has all kinds of files, and no longer appears to be the case for scient, probably because he has decided to include the SMAC 2000/XP Compatibility Update together in an installer.

With AC2 down, I can offer a link to "DOS Days" website and some githubs. It offers Scient, Kyrub and Yitzi patches. Scient is bugfixes, Kyrub improved AI and incorporated an earlier Scientt. Yitzi incorporated Kyrub and an earlier version of Scientt, but is more extensive and may not work for all Mac users. Induktio's mod farther down is more recent, and probably has "the most extensive AI improvement this game has ever had", but includes combat/tech cost modifications. This mirror is largely up to date to when I had previously reviewed the game, but has kyrub version "K". Kyrub has a version "P" in a still functioning post below mine. Alphabetically, P may his last update.

Induktio's 2023 thinker mod page has links to some other downloads including smac-in-smacx.

Civ fanatics is also hosting AI growth mod (2024), which is formally a mod, and not just a patch. AC2's site ("Uncle Buster") had a number of graphical and custom faction mods, but I am afraid they've never been my focus.
https://forums.civfanatics.com/resources/smacx-ai-growth-mod.31053/

Including earlier scient bugfixes, Kyrub's AI improvement was extensive. if Induktio's or Yitzi's changes are a deal breaker. Kyrub has a link on his own post farther down that may have been his last update.

Apart from an inclusion of bugfixes (including scient), Induktio's thinker mod focuses on AI improvements, and improving map generation (which can be disabled). If you don't mind those things, I would have counted it just as an unofficial patch, but it does also modify combat with an intention to improve it, including reduced healing, helicopter range, and tech costs. Although Kyrub contributed a great deal, Induktio the more recently updated mod, if you're up for these change some time.

If you are having a problem running AC, try solutions mentioned in these thread.

They are listed by date of release. Apart from my update listed above, I had last attempted to update the table in 2022 before AC2 went down. Some information may be out of date.

===Unofficial patches detail===
The patches are listed here chronologically and are also listed at this location.
http://alphacentauri2.info/index.php?action=downloads;cat=2

Scient's patch (2010-2019)
1) Originally released in 2010, Scient's patch fixed a number of crashes, bugs, and exploits. V1 removed the unit limit but this was reversed in later and other patches due to crashing large games. Originally for the expansion, it is now available for both games. It was updated to 2.0 in 2014, but was incorporated into Yitzi's patch and not released separately until 2018. It was finally updated in August 2019 to version 2.1.

Kyrub SMAC 2010-2015?
2) Released in 2011, this patch uses Scient's 2010 release. The latest 2014/2015 release, SMAC 444 (version _p) for the original game (SMAC), adds bug fixes to the game and experimental alterations to the AI intended to improve it. The AI improvements may be considered the primary feature of the patch.

Kyrub SMAX 2012
Kyrub ported a number of the fixes he made for his SMAC patch to a patch for SMAX, the Unofficial patch PLUS. This patch hasn't been updated to his latest SMAC 444 patch, and the AI only has some improvements related to terraforming.
http://alphacentauri2.info/index.php?action=downloads;sa=view;down=108

Ytizi SMAX 2012-2017?
Started in 2012, Yitzi's patch for the expansion (SMAX) builds on Kyrub's SMAX patch, but reportedly incorporates Scient's 2.0. It was last updated to v3.5d in 2017. Besides a number of it's own additional bugfixes and inclusion of Kyrub's AI enhancements from that patch, it also improves the modability of the game.
http://alphacentauri2.info/index.php?action=downloads;sa=view;down=352
http://alphacentauri2.info/wiki/Yitzi%27s_patch

Yitzi's patch now includes PlotinusRedux's PRACX for resolution changes. This can also be downloaded separately at alphacentauri2.info.

Dio's Unofficial SMAX Patch Version 1.1 2015/2019
http://alphacentauri2.info/index.php?action=downloads;sa=view;down=321
Initially released in 2015. Requires Yitzi's patch. "enables various features associated with probe teams having a green morale level". Dio's initial contributions to bugfixing were apparently incorporated into the main Yitzi patch, but Dio's patch was updated again in 2019.

SMACX Thinker Mod 2018-2024
https://forums.civfanatics.com/threads/smacx-thinker-mod.682321/
https://github.com/induktio/thinker
https://alphacentauri2.info/index.php?topic=21013.0
Released in 2018, this AI mod/improvement includes Scient's 2.0 patch and states that is compatible with SMAC-in-SMAX.. It also attempts to balance starting faction placement, and makes it possible to select which landmarks are placed on random maps.

Will to Power refers to the AI in this patch as shockingly smart.
Creator invites and requests bug repots directly to the github rather than the AC2 forum

SMAC-in-SMAX updated 2019
https://github.com/DrazharLn/smac-in-smax
"These files let you play an only mildly alderated Sid Meier's Alpha Centauri in the Sid Meier's Alien Crossfire engine. You might want to do this to benefit from various unofficial patches for Alien Crossfire."

SMACX AI Growth mod 2018-2022
https://alphacentauri2.info/index.php?topic=20959.0
Released in 2018, this mod includes AI and other improvements, but also modifies the game in other ways including an attempt to round out the factions. The mod continues to be updated at time of this page's update, October 2022.

SMACX The Will to Power 2020-2022
https://github.com/tnevolin/thinker-doer/releases
https://alphacentauri2.info/index.php?topic=21359.0
Includes Thinker Mod.
Includes a revamping of unit/cost/combat system, favoring defenders but with more randomness.
Modifies the technology tree.

===Miscellaneous===

I also wanted to post Alpha Centauri's backstory (fiction) here, which isn't currently in the extra's section of the gog download page. Originally on the official page before it went down, an archive of the site was reposted on //alphacentauri2.info.
And I wanted to recommend the research assistant on the second link.

Major update of SMAC_444 patch, about 70 assembly hits for a ruthless SMAC AI.
Download link

The patch does *not* work with SMAX (I am sorry, I had/have no time for it; I have not got even the time to finish this).
The patch includes scient's latest patch, fixing a good number of bugs.

Features
- AI will stand up and fight in air wars. It builds a lot more AAA defenders, it uses planes for other things than bombing formers. You may see it use hit and drop tactic.
- AI will attack with while in "hurry" (with 2/3 strength etc.). It should counterattack from bases more.
- AI sees enemy probes as a primary target and may go long way to destroy them.
- AI uses more intelligent pattern for city spreading. AI colpods will now rarely walk half map somewhere.
- AIs ruthlessly exchanges technologies between themselves, hopefully this makes them competitive until later stages of the game.-
- AI likes buildings a lot more. It is able to rebuild its hedaquarters now. It loves orbital pods.

+ [older features]

This update was untested, only for crashes. I saw just 1 test game, the early signs were good, but who knows.
I'll be glad to hear reactions and feedback.

Thanks for working on SMAC kyrub, gonna start a new game today so I'll load up the patch.

I'd say the change is mildly dramatic.
Posted April 15, 2014
For those of us knew to SMAC/X, could you advise which unofficial patches are pure bug-fix patches, ie. don't add any new features? At the moment only (1) seems to fit that bill, strictly speaking, unless the AI improvements in (2), (3) and (4) correct glaringly poor AI decision-making without going overboard. (5) would seem to be right out.

Also, if we install (1), which additional patch should be applied to correct the crash caused by the unit limit removal?

caiman: For those of us knew to SMAC/X, could you advise which unofficial patches are pure bug-fix patches.
Kyrub's patches don't add any features (besides bugfixes) to the game other than AI improvement. Yitzi has begun including bugfixes which I would consider to really be modifications but I don't personally consider the modification extensive at this point to be of worry for anyone who might not want modifications.

Scientt's patch is the only one that tried removing the unit limit, but you could probably install it if for some reason you don't want the AI improvements. Your game would only crash at 2000+ units on the map. Seeing as there were recently a lot of people using it, it's entirely possible you won't run into this.

I believe all of these patches are just EXE files. There aren't any installations.
If you want or don't mind AI improvements, and want bugfix SMAC, get Kyrubs patch.
If you do not wants AI improvements, Yitzi's SMAX patch is built on Kyrub's SMAX patch, which only has improvements to terraformer AI.

Scientt's foundational patch for SMAX, which all the others are built on, is outdated in bufixes and also has no AI improvements.

Which of the unofficial patches are more stable when it comes to running it in widescreen? (1080p)
Posted April 18, 2014
Edit: Yitzi's patch now includes PlotinusRedux's PRACX for resolution changes. This can also be downloaded separately.

BlaneckW: I don't imagine that they have any coding related to widescreen.
Are you having any problems with it?
I bought the game yesterday actually, merely wondering which was recommended since I plan to use the DirectDraw=0 command to get desktop resolution.

hmm, i always get a "server not found" message when i try to get one of the unofficial patches.
Is the alphacentauri2 website down?
Is there any other possibility to get the unofficial patches?

I'm not having any problems. Are you still having problems? Private message me.

Yeah, the whole alphacentauri2.info seems to be offline. Last night the main page had some errors, today there's some content but not much. So all the links are dead right now. Sucks, 'cause I was in the mood just today.
