move and replace each files from patch folders to game folders. If you're worried about replacing wrong file, you'll have to look at the date in the patch. Files with latest date is the one you want to put into the contents folders of the game. Older dated files should already be present in game, but you can replace them if you want. Just pay attention to the name of the folders you're opening and make sure they match from patch to the game. Hope that helps.
