It's first time I've been trying to mod something. I followed your instructions, but I can't put to work.
Here's what I did:
I created a seperate folder.
I copied historic_events.txt.strings and descr events to this folder.
After I download the reader/editor program I opened it and opened the historic_events.txt.strings, but the format is different. The format you mentioned is in the historic_events folder. So now I'm confused with the instructions you gave.
Which of these files should I work with? Or both?
Edit: I have solved the problem I was having. Thanks for your instructions.
