This is followed by seven lists which encode a list of valid rooms (if top bit is set) or permitted areas (0, 1 or 2) for a given route and step within the route. Each list is terminated by $FF.
Note that while routes encode the transitions _between_ rooms, this table encodes individual rooms or areas, so each list here will be one entry longer than the corresponding route.
In the comments below: R<n> => Room n, A<m> => Area m.
