Elmofongo: I like the the open file location, and I know a website that has a fix for Alone in the dark 4
So I download it and put it in a folder of the file?
It depends. If it's a patch executable, you run it and install it like you do with GOG installers, with the possible added requirement that some fan-fixes want to be in the game's folder when run. If it's just replacement files, you just put 'em in the folder and replace the old ones.
So I guess it's usually okay to put the files in the folder. Those fixes just about always come with installation instructions, sometimes in a file named "readme" (it wants you to read it :p ). If you've installed your games in Program Files, you might run into authority issues. Methods for those situations are a pain to explain using text, and to do. I find it easier to uninstall the game and install it in a friendlier folder :p
Also, don't download shady files from shady places. If the site you're getting your fixes from is filled with pictures of naked people beating each other up with plastic phalluses, it might be a great idea to check if there's some other source.
Have you checked the Alone in the Dark subforums already?
