[edit] Overview

Warning: This data is speculative at best. It is collected by using save game text dumps and automated parser from 15 save games that contained 19888 change records for this record type. Data is not verified from actual binary files.

Change records internal formats are still unknown. At best you can see here:

1. Is change record's length constant or variable.
2. Flags that are indicating change record's existence in the record.
   • It is assumed that "None", "Low", "High" and "Mid Low" change records doesn't have flags. Existence of these change records is depending to other - currently unknown - information.
   • If there is more than one flag, then it is possible that there multiple flags indicating change record - or there wasn't enough data to find single flag.
   • It is also possible that multiple change records are sharing same flags or change records are actually same record - they just have different name in dump file.
3. Change record's minimal and maximal lengths.
4. Possible substructures lengths inside change record. This length is largest common divider from all change records minimal and maximal lengths.
