SimCity 4 Saved Game

SimCity 4 Saved Game files are binary save files created by Electronic Arts' SimCity 4. They store the complete state of a city or region - terrain, road layout, buildings and zones, city services, and simulation data - so players can shut down and later resume their progress exactly where they left off.

SimCity 4 writes .sc4 saved games when the player saves a city or region. These files are used only by SimCity 4 to load that city or region's state back into the game; they are not interchangeable with formats from other games. Small-region .sc4 files can sometimes be imported into The Sims 2 as new neighbourhoods, but medium or large region saves are not compatible.

Inside an .sc4 save file is a proprietary archive format known as DBPF (Database Packed File) used by Maxis in SimCity 4. The file begins with the ASCII signature "DBPF" followed by a set of resources (subfiles) indexed by type-group-instance identifiers, many of which are compressed. Subfiles include PNG image data (identified by signatures such as "PNG" and "IHDR"), compressed map data, and metadata entries ("GENERAT", "TEMP.PNG", "IDATX", "TRANS" etc.) that hold the pieces needed to reconstruct the city environment.
