root\theatres_and_region_keys
This directory has 7 theatres_and_region_keys, each one representing a map or trade theatre. The rows in each 'root\theatres_and_region_keys\theatres_and_region_keys\theatre' are as follows:
Theatre number: 1 = america, 2 = europe, 3 = india
Map coordinate left;top (used to calculate the total area the theatre covers)
Map coordinate right;bottom (used to calculate the total area the theatre covers)
Type: true = trade theatre, false = not trade theatre
Regarding the negative numbers on this map 0,0 is at the centre of the map and as you go down or left the number decreases, and as you go up and right the number increases.
Based on their location I believe these theatres are in the following order: 1st indonesia, 2nd america, 3rd europe, 4th india, 5th madagascar, 6th brazil, 7th ivory coast.
root\theatres_and_region_keys\region_data\regions
Each of the 'regions' files refers to a region in ETW, including the land, sea, and impassible regions. Their description is as follows:
Region name

Map coordinate left;top (used to calculate the total area the region covers)
Map coordinate right;bottom (used to calculate the total area the region covers)
Theatre: -1 impassible / wilderness, 1= america, 2 = europe, 3 = india
root\theatres_and_region_keys\region_data\regions\settlement and slots\slots_descriptions
Each 'region' entry represents a region on the map and the slot description represents settlements and buildings. Oddly I couldn't find an entry for the region's colour.
The first line varies a lot an can be any of the following so I'm not sure what to call it:
settlement
region name): (settlement name): settlement_minor [minor city]
settlement
region name): (settlement name): settlement_fortification [fortifications around the city]
town
region name): (settlement name) [town]
(resource)
region name): (settlement name) (location) [resource]
The next lines are simpler:
What this entry is for (fortifications, resource, town building, etc)
Settlement's location
Settlement's location
unknown, 57344 = settlement, anything else = port
Whether you can construct anything: true = can construct, false = can't construct (so if a town already has a building you can't build another one)
That's all I've found so far.
