Sorry - I forgot to mention I do not use GALAXY GOG and never will. It messed up my games several times, something Steam and Origin have never done. I already own STALKER on Steam, but again - those are purely English versions.
I was told that there are actual STALKER GOG Russian INSTALLERS that install purely Russian version. That is what I want and I got it now, but via "different method" I am not going to disclose. It doesn't matter - I own TWO copies of each STALKER game - GOG Multi-Language version and Steam US versions. There is nothing wrong with getting Russian localization via "different method" in my case. In addition, Multi-Language GOG installer for STALKER contains 5 languages I could care less for, but they also take up extra space, which is precious to me.
Now I need to solve a different problem - I need to downgrade from 1.0006 to 1.0005, which I know how to do for the US (en) version. The US patch comes DRM-free, just like GOG's exe file, BUT Russian patch does not! How can I make it all work?:
I have both GOG STALKER installers - the one that installs the purely Russian version 1.0006 and the one that installs Multi-Language version 1.0006, which comes with separate localization folders in the main directory after the installation.
I want to play the Russian version for sure, but can US patch be used with it without it messing up Russian voices and text?
I can also try this - install the Multi-Language GOG version, and then copy Russian localization files into it. The problem is that when I install the Russian version, there are no localization folders for copy-ing!
What do I do?
