First off I'm aware I'm probably posting in the wrong section and I apologize, however I've been looking through the ridiculous amount of tutorials in an attempt to find a thread that can help me out with what I am trying to do but just about all of the ones I've viewed have nothing but dead links to the necessary programs.. 
What I am trying to actually do:
While playing the Fall Further mod for FFH2 I was disappointed by the style and color of certain cities (Illians, Calabim, etc) and I wanted to change that, I figured maybe an unpaking program with a file converter & editor would work but I realize it's a tad more complicated than that, to which I humbly ask: how can I edit the style and color of cities?
