Simtropolis Members immortalized in SimCity 4!
In our 1st official CoriBoom™ release to the STEX, @CorinaMarie and I have humbly created a mod collectively designed for everyone here at Simtropolis. 
I'm sure many of you will have heard of MySim Mode in SC4. The idea being to establish up to 5 Sims per city, giving them a place to interact and see how they feel and respond to their surroundings from speech balloons.
However, it really only serves as a secondary aspect of the simulation, and doesn't directly influence gameplay mechanics. It's possible to select from a list of 21 predefined characters, or import those you've made yourself from The Sims game. This is all well and good. But in the grand scheme of things, it may seem a bit of a non-personable side show, and not so much everyone's idea of fun.
But fear not, that's where MySimtropolis comes in, allowing community profiles to be immortalized and played as visible characters in the game. Find a house, take up a job, and watch your Sim live, work, and play. This could be inside a ritzy suburban estate, a glitzy skyscraper tower, somewhere hidden amid a town called Middle Of (near Nowhere), on an idyllic remote island, an amazing castle town, or even on another planet!
It's completely up to you... 
Total of 223 Members Included (So Far)
Following the Sign Up thread, we announced the successful breakthrough technical development of a hex editing method. This has allowed data to be imported in the MySim entry format recognised by the game, adding each to the selection panel. There's a seemingly unlimited number of places, and so we've asked members to volunteer and have their ST identity preserved in our mod.
The profile for each MySimtropolis Sim consists of:
- Avatar
- Name
- Gender
- Zodiac
As of this update (14 Dec 2025), the following members are included as part of this initiative:

Skyroguen Odainsaker
From v1.101 (11 Mar 2019) and the v1.136 update (02 Mar 2020), after a community consensus poll, included and honored as a tribute are 10 members who sadly passed away.
Update v1.202 (25 May 2024) includes RobertaME's late brother Skyroguen. He is also immortalized forever in SC4, overseeing the AMPS (Allied Municipal Power of Simtropolis) electricity grid, together with RobertaME.
Update v1.218 (17 Feb 2025) includes Odainsaker, who we were saddened to hear passed away in January 2025. We appreciate all the knowledge you shared to help and inspire others, both here at Simtropolis and in the wider city-building community.
Installation
IMPORTANT: The main files must not be installed inside Plugins, unlike regular SC4 content! 
Inside the zip file there is a readme document and 2 folders:
-
MySim
Copy entire contents to: C:\Users\UserName\Documents\SimCity 4\MySim
This contains the avatars of each Sim as 36x41 BMP files, each featuring TPPT corner transparency. Most essentially it also contains a file named MySims.dat which is the 'brains' behind all the functionality being the hex data.
If the "MySim" folder doesn't already exist, it needs creating at this location.
Note: For the Aspyr/App Store Mac version, this MySim folder must be created at:
/Users/UserName/Library/Containers/com.aspyr.simcity4.appstore/Data/Documents/SimCity 4/MySim
-
Locale (Recommended)
Copy included file to: C:\Users\UserName\Documents\SimCity 4\Plugins
This is an optional file named MySimtropolis_Rulez.dat which serves as an overhaul to the MySim Mode. (See details below for more info.)
Note: For the Aspyr/App Store Mac version, the Plugins folder is located at:
/Users/UserName/Library/Containers/com.aspyr.simcity4.appstore/Data/Documents/SimCity 4/Plugins
Thanks to @c4bl3fl4m3 for clarifying the Mac details!
The Selection Panel
Here is where all the MySims can be viewed. There are 3 rows of 7 per page, and they're all listed in sequence as per the order of immortalization for those who've signed up.
As follows:
The pages can be navigated by clicking each number, and over on the left side there are filter options to sort alphabetically, by gender, or zodiac sign.
Please Note:
Although we've made every effort to ensure data entry is correct, we are human and it's possible there are mistakes. Should you notice anything in error or wish to request an avatar amendment, feel free to post in the main thread, the comments below, or send us a PM to let us know. Thanks!
MySimtropolis Rulez (Recommended)
This is an added bonus which transforms the display of the MySims Mode. The most notable feature is by removing all default Sims from the selection panel. It also renames titles and labels in the menus. It's not required for the MySims to be displayed in the game, but for added authenticity it's something we recommend using too.
In Summary:
- Prevents the default MySims from displaying for selection.
- Renames "My Sim Mode" to "MySimtropolis Mode".
- Renames "Select A My Sim" to "Select MySimtropolis Member".
- Renames "My Sims" to "Resident <CityName> MySimtropolis Sims".
- Plus over 20 other locale edits in-keeping with the MySimtropolis idea.
Note: As an alternative to the main Rulez file, there's also a "Less Rulez" edition available here.
Use this version instead if you wish to preserve the 21 built-in Sims as well.
You can join too!
You may have just become aware of this mod, and at this point might be wondering if you can also be immortalized as a MySim. The good news is it's not too late, nor is there a deadline to join yourself. The idea is anyone can post and be included in the next available slot just like everyone else.
Sign up in this thread:
You can be next...
We'll then release periodic updates to this file entry here on the STEX, including those newly immortalized who are equally welcome to be part of this as well. We plan to do this in batches, aiming for around a weekly basis (time dependent of course on our other current commitments).
Want to share your MySimtropolis pics?
Post in the dedicated Show Us Your MySimtropolis Sims topic.

As a little bonus...
Additionally, everyone who signs up to be included receives a special commemorative profile badge.

Future Idea
In due course as hinted about here, we've got an additional mod planned, expanding on the usefulness of MySims to measure simulation factors with greater accuracy.
Stay tuned!
Special Thanks
From what started as something prospectively small, the response to our idea has been overwhelmingly positive and kind. Cori and I both agree this reception and feedback already fully exceeded our expectations. We're truly grateful for everyone who has decided to get involved, and anyone who still wishes to do so.
Thanks to each and every one of you.
MySimtropolis quite simply wouldn't have been possible otherwise, and this release is our gift to you all.
