Offset: starting at 0x00

0x00: num_cities: byte = 0x5c

Number of cities.

0x01: cities: array[ num_cities ] of struct city (each size 0x26e)

City definitions.

• The order of these is the "definitive" order, since the full name is the best unique identifier.

Structures

Structure: city

Size 0x26e.

0x00: short_name: string(32)

0x20: full_name: string(32)

0x40: city_data: struct city_data (size 0x2e)

0x6e: leader_name: string(32)

0x8e: ruler_name: string(32)

0xae: unknown string(32)

• TODO: is this non-empty ever? (ditto for other two unknowns)

0xce: polit_name: string(32)

Name of the political center or town square.

• TODO: describe what empty values look like

0xee: town_hall_name: string(32)

0x10e: fortress_name: string(32)

Name of the city fortress or castle.

0x12e: cathedral_name: string(32)

0x14e: church_name: string(32)

0x16e: market_name: string(32)

Name of the marketplace.

0x18e: unknown string(32)

• Often contains "Munzenplatz". Possibly this is "central square name".

0x1ae: slum_name: string(32)

0x1ce: unknown string(32)

• Many places have "Zeughaus", which translates to "armoury"; others end in "-turm" (tower?) or "-tor" (gate?). Quite possible this is for one of the unused "rebellion" codepath.

0x1ee: pawnshop_name: string(32)

Name of the pawnshop.

• All pawnshops are named the same; this is either 'Leifhaus' or is empty.

0x20e: kloster_name: string(32)

Name of the kloster (church law and administration building).

0x22e: inn_name: string(32)

0x24e: university_name: string(32)

Structure: city_data

Size 0x2e.

0x00: city_size: word

Size of the city.

• Ranges from 3 (small) to 8 (Koln).

0x02: entry_coords: struct coordinates (size )

City location on the map.

0x06: exit_coords: struct coordinates (size )

Party coordinates when leaving a city.

• When you leave a city, you don't exit at the same point as you entered. The exit coordinates were (usually) selected so as not to place you in an untenable position (the ocean, trapped by a river loop, etc).

0x0a: dock_destinations: array[ 4 ] of word

Dock destination cities.

• This contains the indices (in the cities array) of the destinations available via the city docks the docks.
• 0xffff is used for "no destination". Inland cities have all 0xffffs.

0x12: word

if coastal, side of the river ???[Hamburg] TODO.

• Values are: 0xffff (inland), 0 (north of the river), 1 (south of the river)
• 0 and 1 cities are on or near tidal zones (swamps), and may be subject to flooding.

0x14: word [constant: 4]

0x16: word

Pseudo-ordinal.

• At first glance, this looks like an ordinal offset running from 0 to 0x5b, but 0x18 is missing, and 0x3c repeats.
• This value is probably not used.

0x18: city_type: word (enum ruler)

Type of city

0x1a: unknown word

• 0, 1, 2, or 3.

0x1c: word [constant: 0]

0x1e: city_contents: bitmask[16 bits]

Buildings and locations in the city.

• Bits are on iff there is one of that type of building.

bit 1:	is_kloster:	Is there a kloster?
bit 2:	is_slums:	Is there a slums?
bit 3:	unknown
bit 4:	is_cathedral:	Is there a cathedral?
bit 5:	unknown
bit 6:	is_no_fortress:	Is there no city fortress? A rare case of a reversed boolean. Possibly it's a "has something else" flag, and fortresses are added if it doesn't have the other?
bit 7:	is_town_hall:	Is there a town hall?
bit 8:	is_polit: [constant: 1]	Is there a political center?
bit 9:	[constant: 0]
bit 10:	[constant: 0]
bit 11:	[constant: 0]
bit 12:	[constant: 0]
bit 13:	docks:	Are there docks?
bit 14:	unknown
bit 15:	is_pawnshop:	Is there a liefhaus (pawnshop)?
bit 16:	is_university:	Is there a university?

0x20: word [constant: 0]

0x22: qual_black: byte

Quality of the blacksmith.

• This, and the other nine qualities, all seem to work in the same way.
• A zero value indicates that the city does not have that particular shop.
• Non-zero values do not exactly equal the quality of the items available, but merely indicate relative qualities! For example, Nurnberg has a 0x31 (49) listed for the armory, but offers q37 (0x25) armor. However, if one city has a higher value than another, then that city's items will be of equal or greater quality.
• The quality of the healer is not stored here, but is apparently random. (TODO: verify?)
• TODO: comments about Quality of the alchemist, university, pharmacist being the seed thing.

0x23: qual_merch: byte

Quality of the merchant.

0x24: qual_sword: byte

Quality of the swordsmith.

0x25: qual_armor: byte

Quality of the armorer.

0x26: qual_unk1: unknown byte

0x27: qual_bow: byte

Quality of the bowyer.

0x28: qual_tink: byte

Quality of the tinker.

0x29: qual_unk2: unknown byte

0x2a: qual_cloth: byte

Quality of the clothing merchant.

0x2b: byte [constant: 0]

0x2c: unknown byte

• Since the following byte is 0 or 1, this and that might actually be a single word value.

0x2d: unknown byte

• Either zero or one (only a couple of ones).

Enumerations

Enumeration: ruler

Type of city (free, ruled, capital)

• This controls which message from $CITYE00.msg is given when you are approaching a city.
