[HOW TO] Patch Arcanum with UAP and other essential extras

A comprehensive guide for utilizing the Unofficial Arcanum Patch by Drog Black Tooth on Windows 10 and Windows 11. This guide will help you eliminate common bugs found in the original version, enhance your gameplay with useful tweaks, and increase the challenge for more experienced players.

Patching Arcanum with UAP

download link: https://terra-arcanum.com/drog/uap.html#download

Use the mirror of your choice.

The downloaded file will be in the default folder, normally this is the Downloads folder.

Preparing UAP executable

Right-click on the file named UAP2.0.2.exe and click on Properties.



Tick the Unblock box.



Select the Compatibility tab from the top selection and tick Run this program as an administrator. Click OK.

Installing UAP

Double click on the UAP executable. And click Next.



Click on Browse and locate the Steam installation of Arcanum.

In my case, I install games on a separate hard disk.

It is imperative to select the second Arcanum folder. Click OK. Then Next.

Selecting components to install

In my opinion, it is best to install all options reason being that all selections including those of the Beta Content and Misc Mods have been rigorously tested throughout the years and Drog Black Tooth has personally curated them.

Should one not be convinced, tick only if the description seems reasonable.

Finishing with UAP

Untick Show Readme. The content of the document is the same as found in Drog's website so it's an unnecessary task to undertake.

Click Finish.

This completes UAP itself.

High Resolution Patch & DDraw

After installing UAP, the second Arcanum folder should contain a directory called HighRes.

Editing the configuration file

Within the HighRes directory is a settings file called config.ini. This houses settings that pertain to the game itself and how it will be rendered on screen. Open this file using Notepad. No fancy text editors are necessary.

Following is my configuration file in its entirety.

//Arcanum High Resolution Patch Settings

//Basic:
Width = 1280 // original: 800 - as per screen resolution
Height = 720 // original: 600 - as per screen resolution
BitDepth = 32 // original: 16
DialogFont = 2 // 0 = size 12, 1 = size 14, 2 = size 18
LogbookFont = 1 // 0 = size 12, 1 = size 14
MenuPosition = 1 // 0 = top, 1 = center, 2 = bottom
MainMenuArt = 0 // 0 = black, 1 = fade to black, 2 = wood
Borders = 1 // 1 = add borders to most UI graphics

//Graphics:
Windowed = 0 // 0 = fullscreen mode, 1 = windowed mode
Renderer = 1 // 0 = software, 1 = hardware
DoubleBuffer = 1 // 0 = disabled, 1 = enabled (unless windowed)
DDrawWrapper = 1 // 1 = install DDrawCompat wrapper (for Windows 8+ - prevents sluggish speed) 
ShowFPS = 0 // 0 = no change, 1 = always enabled

//Advanced:
ScrollFPS = 60 // original: 35, max: 255
ScrollDist = 30 // original: 10, infinite: 0
PreloadLimit = 30 // original: 30 tiles, max: 255
BroadcastLimit = 30 // original: 10 tiles, max 255
Logos = 0 // 0 = skip Sierra/Troika logos
Intro = 0 // 0 = skip the main menu intro clip

Notable settings are:

• Width & Height entries - for Windows 10: Right-click on desktop --> Display settings --> Display resolution --> First value is Width, second is Height.
  
  
• DialogFont & LogbookFont - My personal preference is to set them to their highest setting because if using high-resolution monitors, the text would look very small.
  
  
• DDrawWrapper - is a source of frustration for many, see below.

Activating High Resolution

Double click on _install.bat. A command prompt window should appear and quickly disappear. The process is automatic so there is no more interaction unless an error occurs at which point you will have to press enter and start afresh this section.

Editing config.ini

When updating the config file, it is imperative to follow this procedure otherwise the changes in the config file may not be executed.

• activate _uninstall.bat
  
• edit config.ini
  
• activate _install.bat

DDraw Alternatives

Before looking into other DDraw alternatives, it is imperative to disable the DDrawWrapper setting in the config file from 1 to 0. Check the above Editing config.ini section for instructions on executing the config file.

DDraw Unwrapped

Another possibility is to disable DDraw altogether. This comment states that on Windows 10 configuring the following settings as follows is enough for an enjoyable experience.

• Renderer to 0
  
• DoubleBuffer to 1
  
• DDrawWrapper to 0

Concluding Remarks

Effectively, the patching part of the game ends here but I always spice up my install with some convenient hacks to make the game less torturous in certain aspects and challenging in others.

So, you may wish to stop here if you want to experience the game as intended, therefore, just a mostly bug-free playthrough. For those, who have been playing the game for a very long time and wish to eliminate some tedious workings, then I humbly suggest skimming through the following section.

Inactive Objects

Every object that is n tiles away from the PC is inactive, i.e. AI, animation, scripts, etc don't work that far away from the player, so the objects are frozen awaiting action. At extremely high resolutions (like 2600x1900) or with the infinite scrolling option it may be possible to see such inactive objects.

Steam Notes

The DirectDraw fix used in the patch is not compatible with Steam overlay, either disable the overlay (right-click on Arcanum in your Steam library -> Properties -> General -> uncheck "Enable the Steam Overlay while in-game"), or simply use the desktop shortcut created by the installer to run the game (but this will not log your playtime).

G-Sync Notes

The high resolution patch is not compatible with G-Sync and the game will not launch, please disable G-Sync before playing.

Windows 11

Besides DDraw, certain settings may ruin the experience of Arcanum on Windows 11. According to this comment, toggling hardware-accelerated GPU can help ameliorate such a situation.

Contents of custom data.zip

This section is about a single zip file that consolidates the mods and config files I use. It holds a curated list that avoids unnecessary grinding while scaling the difficulty in other aspects.

Download link: https://github.com/brandleesee/brandleesee/raw/main/data.zip.

The next step is to right-click and Extract all... in the common/Arcanum/Arcanum directory. It should overwrite some files.

This step is recommended immediately after patching the game with UAP. Once my file is extracted, please edit and experiment to your heart's content.

The following entries explain the contents of my zip file.

Weightless Hack

data/proto/008303 - Armor.pro
data/proto/013081 - Key Ring.pro

Experienced players have definitely encountered this issue. Certain quests require the carriage of extremely heavy items. If not quests it's simply the armour or the amount of ammo carried that slows the player and followers to a crawl. No more! There are some goodies that let this ragtag group fly. (There is no mod that enables flight!)

Wooden Ring (008303 - Armor.pro) and the Key Ring now cancel weight for any NPC or player having same in the inventory. Key ring for main character. Wooden rings for followers. Because acid attacks can destroy the rings, their HP has been increased to 500.

Improved item creation

data/rules/schematics.mes

Originally, the schematics produced a tiny amount of items and ammo. Now the schematics yielded a reasonable amount of items. I may have overdone it on the ammo.

If you feel that the amount produced is exaggerated, then just edit the last entry for each item as you see fit and restart the game.

Please do not give large numbers such as 9999 and 99999 because this will slow down the game significantly.

Better item availability at shops

data/rules/InvenSoure.mes
data/rules/InvenSoureBuy.mes

InvenSource.mes has the items merchants display for purchase while InvenSourceBuy.mes contains the buyback scheme of the shopkeepers. When one is edited the other should reflect the same changes using the appropriate model.

The Starting Barter has been modified, too, to offer the best items in the game.

In order to access all items that a shop has to sell the player must first talk to the shopkeeper and access his wares then back away such that the shop is no longer visible - approximately a screen away - and sleep until morning or for one day. On re-accessing the shopkeeper's wares all items should now be available for purchase.

Because the player starts with a very small amount of cash, the God Mode background has a huge lump to purchase anything available constrained only by the space of the inventory.

Tech Manuals

source[arcanumclub.ru]

data/art/item/i_chemistry_manuals.art
data/art/item/i_electrical_manuals.art
data/art/item/i_explosive_manuals.art
data/art/item/i_gunsmithy_manuals.art
data/art/item/i_herbology_manuals.art
data/art/item/i_mechanical_manuals.art
data/art/item/i_smithy_manuals.art
data/art/item/i_therapeutics_manuals.art

Now, these manuals have artwork on their book cover to easily identify the discipline.

Customised selected Follower AI

data/rules/ai_params.mes

Three characters have become ranged so that they can either concentrate on healing or being technologically aligned will not join the fray and thus reducing the chance of dying.

• Virgil, now, does not join the fray. In my opinion, standard close-combat does not suit him. He stays far from the action and has his rate of defensive and healing spells casting increased.
  
  
• Magnus is no longer a melee-focused character. This because being tech-aligned he is incapable of benefitting from Virgil's heal spell. To keep him away from battles he now specialises in firearms.
  
  
• Sogg is my tank of choice. His minor affinity to heal using potions has been removed. He is now the most complete fighter-follower in the game... not counting Worthless Mutt.
  
  
• Jayna has remained a healer but is an expert in firearms. The difference between her and Magnus is that she is focused more on healing than on shooting. Magnus is western all the way!
  
  
• Raven is now also considered a healer. Her frequency in aiding teammates is less than Virgil's allowing her to fight as necessary.
  
  
• Torian, Gar, Waromon & Sebastian no longer heal others letting them focus on the battle at hand.

Custom selected NPC & Followers Leveling Schemes

data/rules/gamelevel.mes

• Guard has an improved scheme to offer a greater challenge to the player.
  
  
• Pure Melee Dodge NPCs have had their scheme improved to remove any traits that did not let them focus on their natural inclination. Expect no mercy from these guys!
  
  
• Virgil is now a prolific archer and at later levels a much more versatile wizard. He remains the party's main healer.
  
  
• Magnus is now a ranger proficient in firearms.
  
  
• Jayna is now a firearms user with the main responsibility of healing tech characters.
  
  
• Zen Virgil has the same schematic as Virgil. I was unable to locate Evil Virgil's scheme.

Challenging Travel

data/dlg/00123M.dlg
data/dlg/00124M.dlg
data/dlg/00266OrcBanditDialog.dlg
data/scr/00123M.scr
data/scr/00124M.scr
data/scr/00266OrcBanditDialog.scr
data/scr/288die.scr
data/scr/03007OrcBanditDialog.scr
data/scr/03011MhandDialog.scr

These are two difficulty mods that are perfect for those who do not teleport but travel Arcanum on foot.

The orc bandits loitering around the Morbihan Planes and the assassins from the Molochean Hand on your heels now offer a much greater challenge and much more precious loot. The encounters scale according to the player's level. I shall not spoil the surprise any longer.

Backgrounds

Most backgrounds have their starting money amended to benefit from the new inventory and now all start with the weightless key ring. The keyring reduces the mess of consumed inventory boxes to a single item.

God Mode Custom Background

data/mes/gameback.mes
data/rules/backgrnd.mes
data/rules/effect.mes

This background kickstarts the game by making the player formidable from the start. The choices I made are neutral and leave it up to the player whether to pursue magical proficiency or technological. It starts with a huge sum of money to benefit from the updated starting barter.

Removing the Cinematic Intro

INTRO

UAP 2.0.2 includes a patch to block the Troika and Sierra logo animations from playing when starting the game. After the load screen the cinematic intro plays. Having pressed Esc for over 20 years it clicked to me that maybe I could block that as well.

This feature is not included in data.zip.

RESEARCH

- Undatting ArcanumXNoNoise.dat, I found two empty media files of 1kb each titled SierraLogo.bik and TroikaLogo.bik replacing the original intros.

- In the following directory: (D:\SteamLibrary\steamapps\common\Arcanum\Arcanum\modules\Arcanum\movies), the media file 50000.bik is the intro animation.

SOLUTION

1. Rename 50000.bik to 50000.bik.old (thus, keeping it available for later replays)
   
2. Copy either SierraLogo.bik or TroikaLogo.bik from the undatted ArcanumXNoNoise.dat to the Arcanum movies directory (example: D:\SteamLibrary\steamapps\common\Arcanum\Arcanum\modules\Arcanum\movies)
   
3. Rename the copied file to 50000.bik
   
4. Start the game as normal

[PlanktonHatesTheWorld]

Extremely helpful. Thank you for writing this so clearly.

[brandleesee]

Thank you @AV for referring SR's patches. Tested the MAIN file and had good results. Hence, I added a reference in the DDraw alternatives subsection of the guide.

[brandleesee]

UPDATE 18/08/2024 - added new section: Removing the Cinematic Intro

[brandleesee]

You're most welcome, Vxrs!

[Vixiris]

Thanks @brandleesee and @Art Vandelay!
Works flawlessly on Win11 even with the full HD from Nexus.

[brandleesee]

@Kbd, opening directly from Steam does not load the UAP and its modifications.

[Art Vandelay]

@NYARLATH0T3P I had the exact same problem but a small fix made by SCARaw makes UAP 2.0.2 run like butter! Just download it from here (https://www.nexusmods.com/arcanumofsteamworksandmagickobscura/mods/4?tab=description) and copy the files into the installation folder. It should fix all 2.0.2 related problems: flickering, stuttering, crashes, etc.

[Kabirbd]

I know you have directly stated to play from shortcut. But can opening from steam cause issue? It seems to still say unofficial patch on the bottom left when I open it from steam.

[brandleesee]

@RN, no idea!

[brandleesee]

@NY Sorry for the late reply, it could be because of the ddraw.
