Some pieces of information may be out of date or incorrect

A lot of information contained in these files are extracts from the Simtropolis website, from both of the Modding forums. Some information has been extracted from the games own files. Various persons have helped in the deciphering, contribution, &/or gathering of this information. Most notably, the7trumpets, Teirusu, Karybdis, Redlotus & others. While the specs covered go into great detail & cover quite a lot about SimCity 4 networks, it is not completely comprehensive & may contain errors &/or omissions &/or out of date techniques.

Lets begin shall we………. In total there are 32 RUL Files that (originally) come with the game (Rush Hour version). There is also a INI Network-based file. These files (& others) govern how the different networking aspects in SimCity 4 are controlled (or drawn/built in-game). Out of the 32 original RUL files & INI file, some of them have a specific functionality about them &/or in them for the networks. These aspects will be covered in some detail. Follow the links below to a specific area.

  1. Individual Network RULs
  2. IntersectionSolutions RUL
  3. IntersectionOrdering RUL
  4. RuleOverrides RUL
  5. INI Network & Bridges
  6. Paths
  7. Type, Group, Instance IDs

Please note:

  • RUL/INI files are essentially referenced by the exe. Therefore, unless the address of a RUL file already exists within the exe, it can not function. In other words; “new” RULs can not be added without it already having been defined &/or existing in the exe. And thus, new networks can not be added.
  • Items, names, & functions in green are typically actual valid code &/or are from the relative RUL/INI &/or other files.
