Stalker Shoc is a great game, and I love trying out all kinds of Stalker mods: old ones, not-so-old and the latest.
Some of the mods work with different updated versions of Stalker, nowadays usually from Patch versions 1.4. 1.5 and 1.6.
I have multiple Stalker versions installed on my PC from Patch versions 1.4, 1.5, and 1.6.
The way that I have done this is to install Stalker Shadow Of Chernobyl and update it to patch version 1.4.
Then, I made a folder inside the THQ folder called Stalker Shadow Of Chernobyl 1.4 and copied the newly patched version of 1.4 into that folder.
Then I updated the standard Shadow Of Chernobyl game from patch 1.4 to 1.5 and repeated the process, making a folder called Stalker Shadow Of Chernobyl 1.5 and copying the newly patched version 1.5 into that folder.
Then, I do the same for Stalker version 1.6.
I then end up with three patched versions of Stalker Shadow Of Chernobyl 1.4 - 1.5 and 1.6 inside the THQ folder.
Then, inside those folders, I create a mods folder to save my downloaded mods into the corresponding mods folder.
Another thing I do is make sure I download the files that enable me not to have the DVD in my drive.
I create a backup of each Bin folder in each Stalker folder just in case of problems; I right-click the XR_3DA inside the Bin folder and send a shortcut to my desktop.
I then rename that shortcut to the corresponding version of Stalker Shadow Of Chernobyl.
In this way, I can play any version of Stalker I like with any mod that matches the correctly patched version of the game.
pwned!
