...are you saying that you've editted these files and they are NOT showing up in the game? If you edit a descr_buildings file or a trait file or anything like that, the changes SHOULD show up in a game. If you mean to say that you've edited them in a seperate mod, and you want them to take effect in the vanilla game, then you would just drag those files over to where ever they belong in the vanilla directory. Other than that I'm not sure what you could mean.
