This is a small little tool that I put togther, not really sure who the intended audience is but I figured I would post it here. SC4MessageViewer is a small DLL mod that allows the user to view internal engine messages in realtime while playing the game. It also allows users to configure which events are tracked and what they are displayed as. All events are displayed in a small console window that is attached to the game. It goes without saying but this mod is very experimental and, while it is seems mostly stable, tracking multiple messages/events WILL cause slowdown and having an external window attached to the game will lead to unexpected consequences. Use at your own risk. The mod comes pre-configured with a large list of known MessageIds all from @simmaster07, who's gzcom-dll made this project possible. As always, all the code for the mod can be found on Github. Enjoy.

The library is built around reading and loading data from save games, not writing data back to the save file. Although it is now conceptially possible to do so, it would be a quite a bit of work, but definitely possible. If someone would like to take on the task I wouldn't stop them. In terms of reading the contents of the budget subfiles, the structure of the subfiles are apparently known, so an implementation could be added (pull requests are always welcome ).

TLDR; I created an open source .NET library that you can use to easily load data and subfiles from SimCity 4 games. It's called SC4Parser, you can find the source code, documentation (with examples) and the pre-built library over on GitHub. Hi, for the past few months I have been working a tool that creates pictures of maps from SimCity 4 save games. As part of the project I needed a way to load and read data and some subfiles from the SimCity 4 savegames. Unfortunately, dispite the format of SimCity 4 savegames being well documented, I could not find any libraries that did what I wanted and would work with C#. Additionally, most code that I did find also relied the same old C source file to decompress items within the save games, which was a pain to get working with .NET. So in the end I decided to use the excellent research and information on the SC4 Wikipedia to build a parsing library of my own, which may save some people some pain and time. It has the following features: Find and load data/files from save game using TypeID or TypeGroupInstance (TGI) Methods to load common subfiles from a save game (Zone, Building, Transport and Terrain files) Automatic QFS decompression As mentioned above, the library contains a few implementations of common subfiles found in SimCity 4 savegames, some of these implementations are fully complete and others are partially completed but can still be used: Buildings Subfile (Fully Implemented) - Contains a list of all buildings in a city TerrainMap Subfile (Fully Implemented) - Height map for a city Network Subfile 1 (Fully Implemented) - Contains all ground level network tiles (roads, rail, streets etc) Network Subfile 2 (Fully Implemented) - Contains all underground network tiles (subways etc) Bridge Network Subfile (Partially Implemented) - Contains all bridge tiles in the game (decoded during development) Lots Subfile (Partially Implemented) - Contains a list of zones in a city RegionView Subfile (Partially Implemented) - Contains general city information If you are interested, you can find more info about what is implemented, along with documentation and prebuilt versions of the libary as well as the source code over on GitHub. I hope that this provides a useful framework for others to build small tools, scripts and other programs using data found in SimCity 4 savegames and even if you don't use C# I hope that you find the code useful for working out how SimCity 4 save games are put together. Pull requests, issues and features are always welcome. Enjoy.
