This Page Details the Exemplar and Cohort formats of Simcity 4
Lists of the exemplar/cohort properties can be found here: ExemplarPropertiesList
Exemplars/Cohorts can be either Text or Binary (Text formats are found exclusively in maxis plugins) and this can be determined by reading the 4th byte in any exemplar or cohort. In text EXMP files this is T and in Binary EXMP files it is B.
Format Spec Follows
Exemplar and Cohort File Format for Simcity4 by EA. Specification by Buggi, Karybdis, Ilive, Tropod
8 BYTES - The file identifier. Can be EQZB1###, EQZT1### for exemplars and CQZB1### or CQZT1### for cohorts. B denotes Binary format. T is text. 1 is version. 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 properties numerical value. Represented as 0x???????? in Ilives reader and DatGen4. WORD - The properties ValueType. This defines weather its a uint or a float etc. See table below for possible values. WORD - The 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. 80 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.
