in brief, it's a guide of extracting the text files the cfg folder, using

"c:\program files\1cpublishing\space rangers 2 reboot\rangers.exe" extractcfg

then make folder eng (for english) in c:\program files\1cpublishing\space rangers 2 reboot\cfg\ move eng_e.txt to it so the path is

c:\program files\1cpublishing\space rangers 2 reboot\cfg\eng\eng_e.txt

rename the eng_e.txt to main.txt so the final editable file is

c:\program files\1cpublishing\space rangers 2 reboot\cfg\eng\main.txt 
(about 2 MB)

as for the c:\program files\1cpublishing\space rangers 2 reboot\cfg\main_e.txt, rename the main.txt so it becomes

c:\program files\1cpublishing\space rangers 2 reboot\cfg\main.txt 
(about 5 MB)

Now you have two editable main.txt files:
* c:\program files\1cpublishing\space rangers 2 reboot\cfg\eng\main.txt here you can edit to your heart content or until the game crashes Unfortunately the option is limited. The most easily recognized things is under Micromodule, such as changing speed bonus from say 140 on Jake to 2000 or something crazier.
* c:\program files\1cpublishing\space rangers 2 reboot\cfg\main.txt here is where the pointer to graphic files is located and to other things too but i'm not sure what else.

When you're done, compile the txt to dat by using

"c:\program files\1cpublishing\space rangers 2 reboot\rangers.exe" buildcfg

Most important of all: Backup your original cfg folder before doing anything else!
