Just save a copy and put it in your DF/Data/Art/ folder (might be asked to replace a file, that's ok, do it), then go in the init.txt file in DF/init/ and change a few things around with the resolution and which character set you're using. This character set is called maydayMAX, the guy was using maydayMIX beforehand.
Another thing, turn these guys on otherwise you'll get tile stretching
