The following format is used by both Exemplar and Cohort files in SimCity 4. A list of the properties within exemplars and cohorts can be found in the exemplar properties.
Exemplars/Cohorts can be either text or binary (text formats are found exclusively in Maxis plugins) and this can be determined by reading the fourth byte in any exemplar or cohort. In text files this is T and in binary files it is B. The following file specification is credited to Buggi, Karybdis, ILive, and Tropod.
Exemplar and Cohort File Format
8 BYTES - The file identifier. Can be EQZB1###, EQZT1### for exemplars and CQZB1### or CQZT1### for cohorts.
The fourth byte denotes whether the file is Text or Binary (T or B).
The fifth byte is the version number, which in these examples is 1.
DWORD - Parent cohort Type id
DWORD - Parent cohort Group id
DWORD - Parent cohort Instance id
DWORD - Property count. This specifies how many properties are
contained in the exemplar or cohort. Critical to reading the
file properly.
+24 Repetitions of properties follow. Each property varies in size.
Property structure
------------------
All properties have the same basic structure. They start at offset 24 in an exemplar or cohort.
DWORD - The property's numerical value. Represented as 0x???????? in ILive's reader and DatGen4.
WORD - The property's '''ValueType'''. This defines weather its a uint or a float, etc.
See table below for possible values.
WORD - The property's '''KeyType'''. The KeyType contains a value of 0x80 if the property has more than or equal to one repetition,
and 0x00 if it has 0 repetitions. 0x80 is the only recorded KeyType
BYTE - Number of values, or value repetitions, if the KeyType is zero. When KeyType is 0x80, this is an unused flag.
DWORD - Number of values, or value repetitions, if the KeyType value is 0x80. A repetition of 1 represents
properties capable of more than one repetition but held to 1 rep for the moment.
''When KeyType is 0x00, this is a single value as defined by ValueType''
ARBIT - Value repetitions when KeyType is 0x80. Depending on data type, the length of these repetitions varies.
See ValueType below on data types.
