Of the 1482 global variables, less than 50 are missing now. Furthermore, there are some parts of the data segment that are not addressed anywhere in the game. I listed the missing symbols (if I haven't overlooked any, this is a complete list) as well as some of the unclear regions in symbols.h (see the commented out parts).
