What is SimCityPak?

It's a work-in-progress tool that aims to be the iLive Reader equivalent for SimCity 2013. It allows you to view and edit the game assets contained in .package files.

What does the tool allow us to modify?

  • Property Files
  • Javascript/Text Files
  • Textures
  • 3d Models

What will we eventually be able to modify?

For the foreseeable future, we will only be able to make visual modifications - changing textures and 3d models is technically a possibility. Gameplay variables such as capacities, costs etc. are stored in the so-called "EcoGame" folder. These specific packages also exist on the servers, and any action made in-game is checked against the server side version of these packages. Any discrepancies will result in rollbacks. The only way we will ever be able to add any truly new content (buildings etc.) or to change the data in the EcoGame folder is if Maxis updates the game to support this - they have hinted that they're looking into the possibilities for official mod support, but no specifics have been given yet.

Will I be banned for modding?

Maxis has recently released its official modding policy. You can read about it here: http://www.simcity.com/en_US/blog/article/modding-and-simcity

How can I contribute?

There's still many things to do, so every contribution is more than welcome. If you think you've got what it takes, take a look at the Issue Tracker (http://simcitypak.codeplex.com/workitem/list/basic).

Also, experiment! There are already many possibilities for mods - all it takes is dedication and a lot of digging into package files. However - remember to make backups often and to always test in a non-public, disposable region.

Our main place for discussion is at Simtropolis in the following thread:
