Thief 2 Setup and Modding Guide
Thief 2 was built for Windows 9x systems and has a hard time running on modern computers.
This guide will help you set up the game using the latest unofficial patches and teach you how to apply mods.
You'll also learn about Fan Missions here aswell as Thief 2X and how to play them.
This guide will help you get Thief 2 running on your computer. The Steam version of Thief 2 is actually the GOG version. They did an OK job of setting up the game and getting up and running for players but that still isn't enough for some people who report crashes and general instability.
The Program Files folder
Let's start off with some important information.
The Program Files folder is a protected folder within your Windows installation that works differently from other folders on your computer.
The long story short is that if you have your copy of Thief 2 located within either the Program Files or the Program Files (x86) folder, you may encounter problems and some, or all, mods may not work at all. This varies from machine to machine and some people may not have a problem at all.
If you think you might be being affected by this, try moving your copy of Thief 2 from the Program Files folder into another folder like 'C:\Games' and launch it. If mods are installed correctly, they may start working for you.
If this is the case, you can make another Steam Library Folder using the Steam Library Folders feature. Go to View > Settings and Click the 'Downloads' Tab to find it.
Click Add Library Folder and make it anywhere you want.
Once you've done this, you can reinstall Thief 2 into this new folder and move any save files and mods you have from your old installtion into this new installation!
Getting the game set up for play
There are two ways to get your copy of Thief 2 up and running. You can use either of the following tools on your Thief 2 installation.
The first is a tool I made called T2Tool. If your looking for a quick and easy way to get Thief 2 running with great default settings and the ability to install mods and bugfixed levels easily then this setup is for you.
Checksum of EXE: MD5: 29DCA09E82AC5CDD5254E9786A61B9F5 SHA-1: 3DAB8AF3463B596ACE95BB750BBC1F2E735FA1CC SHA-256: 517042322CA12B4E2AB9F93E9EC814A17ABEF13B354E31E8F88AD8CA7E0F0D75
Please bear in mind that this tool is programmed not to function at all if the game is found to be in your Program Files or Program Files (x86) directory. You MUST move them outside of this folder as described above.
The other way to get the game setup is to install TafferPatcher; a huge setup file containing community mods, bugfixed levels and other added extras all bundled into one package. It's a bit more advanced than T2Tool and you'll need to do some additional altering of settings once installed.
Now, I hate to break it to you but That's it! Once you've used one of these tools, (Almost) no more work needs to be done! Your copy of Thief 2 is up and running. Of course, you can dive right into the game right now but you can also edit the cam_ext.cfg file with Notepad and you can alter anything you want like post-processing effects, Bloom and 16x AA for some extra added visuals.
Some of the commands works on a Boolean system, 0 is off, 1 is on. Turn features on or off by changing the numbers. Also remember to remove any semi-colons ; in front of the command you want to enable (to disable, just re-add the semi-colon again)
Be sure to make a backup of the file first before you go altering something you might wish you hadn't.
How to install mods
Mods usually come in Zip files. Inside these files you will find one or more folders. Fam, Mesh, Snd and Obj are just a few examples of what these files are called.
Both T2Tool and TafferPatcher (if you install any mods on using the tool) will install a folder called MODS into your Thief 2 directory. Put your mods in here. IF they match the folder structure of the ZIP file then they should work fine.
Some of the levels in Thief 2 have small amounts of bugs in them ranging from loot being placed outside the game world to broken scrolls and misaligned objects.
Luckily for us, a nice Taffer called AntiMatter_16 went through every single level in the Thief 2 editor and fixed all of the bugs!
There are two versions of the Bugfixed levels; one version (1.1e) requires NewDark to be installed and the other (1.0e) can be run on any version of Thief 2. You can install these automatically using either T2Tool or TafferPatcher but if you fancy a manual download instead, you can download the fixed levels from the following places:
1.1e - Requires NewDark 1.21 or above My website[www.saleck.net], My dropbox[dl.dropboxusercontent.com].
1.0e - Will run on Vanilla Thief 2 My website[www.saleck.net], My dropbox[dl.dropboxusercontent.com].
EAX through the OpenAL Library (TafferPatcher Only)
If you have used T2Tool, this section does not apply to you as the installer has set up EAX support for you.
EAX will now work in Thief 2 through the OpenAL library. You can get the OpenAL installation file (oalinst.exe) from here:
Alternatively, the more up-to-date "OpenAL Soft" can be found here[kcat.strangesoft.net]. It will require a manual installation but isn't very difficult.
Once you have installed the library, Start Thief 2 and go to Options > Audio and click on Hardware Acceleration until it shows the Option 'OpenAL'
Now when you play the game, you will have all the echoey hallways you could possibly dream of.
If you want to try something a little different after you've played Thief 2, you could always try one of the many (over 700 and ever growing) Fan Missions released for the game.
You can find Thief 2 missions at the Thief Missions[thiefmissions.com] website.
Once you have a few, you may be tempted to put them straight into your DataTempMods folder but hold on there! It's not that easy.
Long story short, Fan Missions (FMs) may not be 100% functional if you do this. Luckily, The NewDark version of Thief 2 comes with a Fan Mission loader called FMSel.
To use FMSel, Right click on Thief 2 in your Steam Games list and click Properties.
Click Set Launch Options and in that box, enter in -fm and click OK.
When you launch Thief 2 again, FMSel will start and ask you to create an FMs directory. Click Yes.
Once you've done that, FMSel will ask you to specify a folder in which you keep your FMs so put all your FMs in one folder and have FMSel use that folder.
Once you've done that, FMSel will list all the FMs it finds in that folder.
From here you can do many different things: Skip FM - Will Launch Thief 2 without using any FM. Play FM - Will Launch Thief 2 with the currently selected FM. It will ask you to Extract Archive which, when Yes is selected, will install the FM into the FMs folder. Start FM - Will Launch Thief 2 with the currently selected FM and set your Status to 'Playing' (I presume this is used for things like Windows Live Messenger and other software)
You can also rate your FMs, Search for an FM in the Name text bar, Read any Readmes inside (Right click > View Info File) and many other things.
Here are some questions you may have:
All my Thief 2 save files have gone! What have you done?! Don't Panic! Your save files are still there. When Thief 2 is launched with an FM, you get to have seperate saves! These are stored in your FMs folder. Every time you launch that FM, you'll see your saves there again from the last time you played.
Will my installed mods work with an FM? They should do but it depends on the FM; some use custom health indicators and light gems so they will take priority when loaded. Other than that, mods should work OK.
Can I install mods this way too? No.
Will Thief 1/Gold FMs work in Thief 2? That's a question with many different answers but the short answer is they should do. Thief 2 FMs will most likely not work with Thief Gold due to the extra content Thief 2 has.
Can I hold you responsible for anything daft I do like try to install System Shock 2 FMs into Thief 2? Nope.
How to play Thief 2X: Shadows of the Metal Age
If you've never played, or heard of, Thief 2X, you should correct that right now and get it. It's an amazing unofficial expansion pack for Thief 2.
You can use the Steam Overlay and chat to friends whilst playing, take screenshots etc.
Constant resolution instead of switching back and forth like the default T2X installation does,
Any cam_ext.cfg settings will now apply to T2X. Anti-aliasing, Bloom and other effects will work,
You will need to rename your MODS folder to something else to play Thief 2,
Any T2 saves can be accessed by T2X and vice versa,
Simply Install T2X into your Thief 2 installation and, once completed, delete the Darkinst.cfg file located in the T2X folder and move the contents of the T2X into the MODS folder. When you start Thief 2, Thief 2X will start instead.
If you have the T2X Installer, go ahead and install it now into your Thief 2 installation folder. Once installed, you will need to download a replacement Darkinst.cfg file and place it into your T2X folder.
Once you've done this you can run T2X from the Shortcut on your Desktop!
OK, you should now have a fully working copy of Thief 2. It should now be playable on Windows Vista/7/8 in glorious widescreen with EAX and fully mod ready!
Here are some pictures of the game in 1920x1080 I took after following my own guide.
Now, go get your sneak on and enjoy this incredible sequel either for the first time or for a re-visit. Just make sure you go and play the original too at some point :)
Thanks for reading. This guide is from my own website at http://www.saleck.net/creations/gamefixguides/thief2.php.
