SC4 Savegames by various decoders
Savegame (.sc4) files are DBPF files, containing a number of files specific to the city, including various subfiles, like Network Subfiles, the Building Subfile but also the Advisor Subfiles, etc. They can be opened with Reader by ilive and the SC4 Savegame Explorer by wouanagaine. However, as critical parts of the file encoding have not been discovered, and Maxis used a checksum algorithm on these files, voiding them when anything is changed to them outside the game, there is currently no editing program capable of successfully modifying these files except for SimCity 4 itself. Some of the files have at least had their purpose identified and been named, while even fewer have been partially or fully decoded.
