Notes:

• Sometimes I've given the 'effective' format, not what the game actually uses.
• When I say something like 'c_str' I mean an array of char with terminating null.
• Never include `'"{}s.
• Pointers are all offsets (in 8bit char's) from the beginning of the file.
• MapID is just gibberish that is[or should] only used to identify two almost identical maps as different.

The SMT description will hopefully appear in the future.

Double check this information, no guarantees.
