Where is Tools/Unpacker folder?

[Rhyfelwyr]

I installed the patch (I think). As a result, the tools/unpacker folders were created, and so I run the files etc, and now I can edit data files. Also, I deleted the geography files, and battles work. However, theres nothing in the main menu to say I have patched the game.

EDIT: Even though I have edited text files for unit stats, the changes do not appear in game. I think this is because I did not create the batch file. How would I do this?
