@ciane thank you so much for answering!
About those .nhd files - as I was saying, initially I meant these text files from the expired 4shared links (I believe they are .html from what I see in the URL):
"word document: http://www.4shared.com/file/H1XsUr2lba/IPFix.html
open document text: http://www.4shared.com/file/9Hku4NwUba/IPFix.html"
I thought that these files may contain more structured information which would be easier to translate - because I want to make the fullest guide including your save files _and_ the clearest instruction on how to make all necessary changes by yourself and all that detailed stuff. But it seems to me that I've managed to do it anyway ^_^
And yep, I totally get that all necessary changes are already made in your save files, I just wanted to make sure that all individual replacements are also totally playable. I mean, you didn't make two copies of the same lot because one of the copies was corrupted or had some mistakes that you decided to correct in the second version - or anything like that.
