RELEASE NOTES
Before you run off in excitement to install the new NAM version, please make sure to read this document first, to ensure the best Network Addon Mod experience.

Note to users of the EA App/Origin: As of June 2023, digital copies of SimCity 4 Deluxe purchased via EA.com, the EA App, or the Origin Store, or played through EA Play/Xbox Game Pass are now properly patched to Version 1.1.641, which means they are compatible with the Network Addon Mod.
 



New Features for NAM 49

See the Changelog below


INSTALLATION AND GENERAL NOTES

Before attempting to run the NAM installer, ensure that you have extracted the contents of the .zip download into a folder. Attempting to run the installer while it is still in the .zip will cause the installation to fail.

For a complete walkthrough on installation, see the enclosed read-first-NAM-49.html file, or https://www.sc4nam.com/docs/getting-started/

 

The minimum requirements for running the Network Addon Mod are as follows:

  • A compatible retail copy of SimCity 4 Deluxe Edition OR SimCity 4 with the Rush Hour Expansion Pack:
     
    • Windows/Linux (via WINE): Any digital retail edition, or any disc copy updated to at least Version 1.1.638.
       
    • macOS: Any recent digital edition of the Aspyr port for macOS (installation on the App Store version is more difficult, and the NAM Team is limited in our capacity to provide installation help to App Store users).
       
    • The now-rare non-Deluxe/non-Rush Hour copies of SimCity 4 are not supported. Attempting to run the NAM on a non-Deluxe/non-Rush Hour copy of SimCity 4 will cause the game to immediately crash to desktop (CTD).

       
  • Java Runtime Environment (JRE), in order to run the installer--a version for 64-bit Windows is included in the download (OpenJDK11U-jre_x64_windows_hotspot_11.0.8_10.msi).
     
    • If you are not on 64-bit Windows and need Java, Adoptium's open-source edition is recommended, though JRE and JDK can also be acquired in proprietary/commercial (but free to download) form from Oracle at Java.com.
       
    • The Java Development Kit, or JDK, will also work, but contains extra files not needed unless you are a Java developer.

       
  • A system with the following specs, for each basic type of NAM installation:
     
    • NAM with a LowRAM/NoRHW Controller option: Any system built within the last 15 years, with 750MB available disk space. (Users running this option cannot install the RealHighway (RHW) features.)
       
    • NAM with a Full 4GB Controller option: Any system with a 64-bit operating system, at least 4GB RAM, and 1.2GB available disk space. If on Windows, the 4GB Patch must be applied to the game's executable.
       
    • NOTE: Installing the Full 4GB Controller option without meeting the specifications and without the 4GB Patch will cause the game to crash-to-desktop (CTD) upon attempting to load a city. If you experience this crash, it either means your system does not support the Full 4GB Controller option, or there was some form of failure in the 4GB Patch process.
       
    • Additional Requirement on Windows/Linux (if running Full 4GB Controller/RealHighway options) (not required on Mac): 4GB Patch by NTCore (included in download, automatically installed on Windows with standard installation procedure, and also available at NTCore).
      • See Step 3 (under "On Windows") or the 4GB Patch section in the read-first document for more details.
         
  • Additional Requirement on Mac (optional for Windows/Linux): JDatPacker by memo.
    • JDatPacker is a tool for consolidating folders of SimCity 4 plugins. This can speed up the game's performance, and on macOS, this helps alleviate issues with the Aspyr port's known "number of files limit", wherein exceeding a certain number of files/folders within the game's Plugins directory can cause the game to crash.

 

To install the Network Addon Mod:

  1. Install the Java Runtime Environment (JRE) (if already installed, skip to Step 2).
    (This is included in the download package.)
     
  2. Remove any existing NAM installations, if present (simply deleting the "a_Network Addon Mod Lite" and/or "Network Addon Mod" folder from the Documents\SimCity 4\Plugins directory is the easiest way).
     
  3. Run the NAM Installer:
    • On Windows:
      • If it your first time installing the NAM (or you are installing on a new system/with a new SC4 install), use NetworkAddonMod_Setup_Version49.bat. If you are upgrading from a previous version, or have manually installed the 4GB Patch already (see the 4GB Patch section in read-first), use NetworkAddonMod_Setup_Version49.jar. (The .bat file has a routine to automate the 4GB Patch installation process, necessary to avoid CTDs if running the Full 4GB Controller option, which is necessary to use the RealHighway (RHW) features.)
         
    • On macOS:
      • Run NetworkAddonMod_Setup_Version49.jar.
      • If on the App Store version, the installer cannot directly install into the Plugins location the App Store version utilizes, which is inside the .app file (~/Library/Containers/com.aspyr.simcity4.appstore/Data/Documents/SimCity 4). Install to an alternate location first, then copy the resultant "Plugins" folder into that location. Note that the NAM Team is currently very limited in our ability to provide installation assistance to App Store users.
         
    • On Linux:
      • Run NetworkAddonMod_Setup_Version49.jar, or, if that fails, run NetworkAddonMod_Setup_Version49.sh.

         
  4. Follow the installer's instructions, clicking on each tab on the top bar in order:
     
    • Agree to the mod's terms on the initial "welcome" tab to proceed with the installation.
    • Select the options you would like to install under the "files" tab.
       
    • Select the install location under the "location" tab. Unless you have set up an alternate location for your Plugins folder, or happen to be on the Mac App Store version of the game, this should work fine.
       
    • Finally, move to the "install" tab. Click the "Start installation" button to begin the installation process. When the installation is complete, the progress screen will display a message, "All selected components installed!".
       
    • Close the installer, using the "X" button or, on macOS, the red circular button, in the upper right corner of the window. You're all done installing the mod.

       
  5. Additional step for Mac users (optional on Windows/Linux):
    (Run JDatPacker to consolidate the mod's files.)

     
    • If on the App Store version, run JDatPacker over the resultant Plugins directory, then move the "Network Addon Mod_###.dat" files (wherein "###" is a three-digit number) into the container.
       
    • On the Steam version (or if optionally using JDatPacker on Windows), run JDatPacker on the Documents\SimCity 4\Plugins directory (this will also consolidate your other plugins as well). Make sure you remove the original directories that were consolidated, and, if upgrading or reinstalling your NAM package at any point, ensure you delete any the "Network Addon Mod_###.dat" files from your Plugins before running the new installation. It is recommended that you use a new subfolder (i.e. "Plugins\Compressed Files") instead of installing to the root of the Plugins directory, as this can help prevent mod conflicts.

       
  6. Load the game and enjoy the NAM!
     
    • If the game crashes on your first attempt to load a city, this means you have the Full 4GB Controller installed, but either have experienced a failure in the 4GB Patch process, or have an incompatible system (not enough RAM and/or a 32-bit operating system). Either attempt to install the 4GB Patch manually, or choose a less intensive installation option (the Low RAM/No RHW option, or download NAM Lite instead).
       
    • Note that if you've never run the NAM before, and you've picked a fuller installation option, the initial load of the game, and of the first city tile you open may be longer--often quite noticeably. This will shorten with subsequent loads of other cities, or, if you exit and re-enter the game, subsequent re-entries will be quicker.
       
    • If you do not see any icons in game, this most likely means your installation ended up in the wrong location. Either reinstall, making sure the files go into your Documents\SimCity 4\Plugins folder (true of Windows and the Steam Mac version), or, if you're on the Mac App Store version, make sure you copy the files into the .app container.


More details on installation and compatibility can be found in the enclosed read-first-NAM-49.html file.

 

NAM Lite

As mentioned above, an alternative compact version of the NAM is now available, which can be installed instead of the full NAM installation package.

The NAM Lite features just the most essential of NAM features, including the NAM's renowned Traffic Simulator Plugins, refining SimCity 4's pathfinding engine to work as it was originally intended, along with Automata Controller options, updated textures (including a Euro/International texture option), Roundabouts, Diagonal Streets, additional interchanges for the game's base Highway system (the "Maxis Highways"), and (optional) Hole Diggers/Ground Raisers, allowing for precise terrain alteration.

See here for more details and to download NAM Lite:

Released

New Features for NAM 49

Release Notes for NAM 49 (rev1) (4 March 2025):

  • Bridge Additions and Improvements:
    • Red Truss Arch, Yellow Steel Girder, Green Truss, and Blue Suspension Bridges by IDS2 have been added for Road, Street, One-Way Road, AVE-2, ARD-3, NRD-4, OWR-3, RHW-2, RHW-3, RHW-4, and SAM Sets 2 and 6-11 (68 bridges total).
    • Viaduct Bridges by Kitsune added at L3-L4 for MIS, RHW-4, and RHW-6S, and L0-L2 for Dual RHW-4 and RHW-6S (12 bridges total).
    • Plain Bridges by eggman121 have been added for Hybrid Railway (HRW) at L0-L2 (3 bridges total).
    • Ponte di Piacenza RRW Bridge by Ulisse Wolf added.
    • Yes, that's 84 bridges.
    • Every bridge has had its ceiling height updated (L0/Ground Level=-0.000001, L1=-7.5, L2=-15, L3=-22.5, L4=-30) to allow for a lower ferry clearance and for the elevated bridges to behave as . . . elevated bridges. As result the ferry clearance is now 270.1m / +20.1m. At this time its unknown how to get the in the game message to reflect this value, therefore it will incorrectly state the bridge is not suitable for ferries even though it is.
    • For models where property bridge obstruction = false, they have had the property removed after it was discovered the game is incorrectly treating it as bridge obstruction.
    • Night textures fixed for RRW/Rail bridges, including the Iron Girder, Steel Arch, and Green Garabit Viaduct.
    • A pathing issue with the RHW-10S Cable-Stayed Bridge has been fixed.
    • Bridge Controller file has been renamed from "NetworkAddonMod_Bridges_Plugin_Controller.dat" to "NetworkAddonMod_Bridge_Controller.dat".
  • Mass Transit Authority (MTA) Station Update:
    • Improvements across the board to Station Transit-Enabling (TE) properties.
    • Added SW77 El-Rail-over-Road station.
    • Added several new stations, including the SW77 El-Rail-over-Road station, the Mattb325 Victorian Diagonal L1 Viaduct E-RRW and separate HRW versions, the DBSSYMN Winterton HRW L2 Terminal, the DBSSYMN Winterton L2 Viaduct Rail Terminal, the DBSSYMN Dresden HauptBahnHof, the Oidaas and Tyb06 HRW L1 Station, and the Art128 and Tyb06 Noah Diagonal Tram Stop.
    • Changes to the TE modding on the L2 Diagonal Rail stations, so they are now fully functional with E-RRW, you can just drag through the network on the lot. (They are also still functional with the puzzle pieces).
    • DN/MN prop options added.
    • LHD path remapping has been updated for GLR LOTting paths.
  • Street Network and SAM Improvements:
    • Street and SAM network paths have undergone a comprehensive set of improvements.
    • A texture issue has been fixed with the SAM-7 x Avenue OxO intersections.
    • SAM texture file architecture has been redesigned to ease future additions and maintenance.
    • Shadow remapping and LHD pathing has been improved on Elevated Rail and Monorail crossings over SAM.
    • SAM x RRW crosslinks have been improved.
  • RealHighway Improvements:
    • 3-Level Crossings adjacent to 45° FLEXFly setups are fixed.
    • 45° FLEXFly-over-45° FLEXFly now supported in limited circumstances.
    • The diagonal overhanging models for the RHW-3, RHW-4, and MIS have been redesigned to minimize terrain clipping issues (wherein the terrain would poke through the highway).
    • Major improvements have been made to the Type 21 exemplars on elevated RHW networks, especially those involving placement of support pillars.
    • Diagonal interactions between the RHW-2 and single-tile Maxis networks have been improved, particularly transitions and OxD T-intersections with Street, Road, and One-Way Road.
    • Stability improvements have been made to the L1 and L2 RHW-3 Type A1 ramps.
    • Numerous tooltip texts have been updated to properly indicate current network support.
  • Roundabout Improvements:
    • Thanks to Lucario Boricua, the NAM's roundabouts have received a comprehensive set of pathing fixes, designed to improve capacity and Pedestrian functionality.
  • Other Various Improvements:
    • The NWM's NRD-4 network now has a Diagonal Starter.
    • Various previously-unsupported T-intersections involving Avenues and One-Way Roads have been added.
    • Missing texture for Double Orthogonal Street x Diagonal Avenue intersection has been added.
    • NWM DxD intersections now have improved models with smoother corners and terrain handling. There is also now a non-default option to alter the Road and One-Way Road DxD intersections to use similar overhanging models (the "Wide Corner Road and One-Way Road DxD Intersections" option, found under "2 Additional Network Features > Road, One-Way Road, and Avenue").
    • Raiser/Digger icons have been revised.
    • A new icon has been added at the bottom of the Highways Menu (right near the NAM Controller Marker) to show which capacity level of the NAM Traffic Simulator one has installed.
    • Issues with the Draggable Fractional Angle Road streetlight placement has been addressed.
    • Replaced `EU_Common_Sign_Props.dat` with a version from rivit, which rescales the props to be a bit smaller.
    • Semi-Auto Turn Lane textures have been updated to fix wealth-related issues reported by Dead_End.
    • Duplicate Rural FTL textures in the US folder have been removed.
    • Fractional Angle Road at-grade crossings with orthogonal RealRailway now have paths.
    • The Maxis Highway Override (MHO) Diagonal Bridge Enabler (DBE) support files have been added.
    • rev1 update: Fixes version mismatch issue in the revised One-Way Road Roundabout paths that could cause CTDs with diagonal Road or One-Way Road connections into the roundabout.
  • Like 236
  • Yes 22
  • Thanks 50



User Feedback



Recommended Comments

i downloaded and installed NAM 44 and I gotta say, it was a nightmare.

1. the current readme says if you own the Steam version, you do not need to patch. That is wrong. If you do not patch, you will get a CTD. you will manually need to patch via the patch exe that comes with NAM (manually because see 2.)

2. the .bat executable does not work when run "as Admin" (as was also suggested here in comments), but then will result in the error that the patch exe could not be found in the NAM directory, while it is of course clearly there. you have to run the .bat with double click, not with "run as admin" - this is completely counterintuitive.

3. when I have NAM finally installed, it takes ten minutes (clean SC4 install, no other plugins whatsoever) to open/create a city on a lesser (2 year old) work laptop, and still 6 minutes on a dedicated gaming laptop.

this is supposed to get better AFTER the first boot up /w NAM, as things to get loaded in for the first time, I understand? but when will it get better, as with my second and third boot up it still took so long?

Is it just freezing (and you're having to Ctrl-Alt-Delete or otherwise manually close the game), or is it actually crashing to desktop on its own?  If it's merely freezing, keep in mind, if you've never played with a larger plugins folder (a full NAM install runs about 1GB, and one of the main files is especially large), the game will take longer to load.  It may simply still be loading rather than actually freezing (note that subsequent loads of city tiles after the first one will be quicker).

If it's actually crashing to desktop on its own, and you're on Windows, that's a sign that you're running the Full version of the NAM Controller, and either (a) the 4GB Patch wasn't installed properly, or (b) you're on a system that's not capable of handling the Full NAM Controller (i.e. you're on a 32-bit version of Windows, you have less than 4GB RAM, or both).  Try running the .bat file again, right-clicking it and selecting "Run as administrator", and making sure the command prompt window that pops up indicates the 4GB Patch was successfully installed.

-Tarkus

so you mean that initially the first boot up with NAM will take long, but after that booting up the city will not? or what does "subsequent loads of city tiles" mean?

because i installed NAM on a fresh SC4 installation without any other plugins, and it takes 5 minutes to load into a just created city (with stuff to load, as there is nothing built yet). I just want to know if this will get better, because i am at a loss here. thanks in advance!

Descargué e instalé NAM 44 y debo decir que fue una pesadilla.

1. El archivo Léame actual dice que si posee la versión Steam, no necesita parchear. Eso está mal. Si no parchea, obtendrá un CTD . necesitará parchear manualmente a través del parche exe que viene con NAM (manualmente porque vea 2).

2. El ejecutable .bat no funciona cuando se ejecuta "como administrador" (como también se sugirió aquí en los comentarios), pero luego dará como resultado el error de que el parche ejecutable no se pudo encontrar en el directorio NAM , mientras que, por supuesto, es claramente ahí. tiene que ejecutar el .bat con doble clic, no con "ejecutar como administrador"; esto es completamente contrario a la intuición.

3. Cuando finalmente instalé NAM , se necesitan diez minutos (instalación limpia de SC4, ningún otro complemento) para abrir/crear una ciudad en una computadora portátil de trabajo menor (de 2 años), y aún 6 minutos en una computadora portátil dedicada para juegos.

se supone que esto mejorará DESPUÉS del primer arranque /w NAM , ya que las cosas se cargan por primera vez, ¿entendido? pero ¿cuándo mejorará, ya que con mi segundo y tercer arranque todavía tomó tanto tiempo?

HII, I have never had any problem since NAM 38 and I have a folder full of plugins, I think some errors are random, sometimes an old region takes less time to open than a new one, currently I have a huge region and everything takes 5 minutes the process of launching the game and reaching a city in the region, and sometimes 10 minutes and sometimes less than 5, is all very random.

P.S. some plugins don't work due to age or duplicate files, that's where sometimes the NAM doesn't start right and I was cleaning from NAM 42 before installing.

1.  There's two different patching process--the 4GB Patch, and the Maxis patches (Version 1.1.638 and 1.1.640).  Right at the very start of the Release Notes section, you'll notice it states "Note that without the 4GB Patch being properly applied to the game by Windows (and Linux/WINE) users (or the use of the "Low RAM/No RHW" Controller option for users on lower-spec systems/32-bit operating systems), the game will crash to desktop."  Anyone running a Windows version of the game needs the 4GB Patch to avoid the CTDs, whether it be from Steam or anywhere else, and this is all over the documentation, and in the first page of the installer itself.

The Steam version does not require the Maxis patches, however, as it's already at Version 1.1.641, and any references to the Steam version not needing patches are referring to this, not the 4GB Patch. 

2. Running an executable file (including a batch file) as an administrator should give it additional permissions, not fewer, so this is very strange.  We have had users report 4GB Patch failure, in spite of following the instructions, and the general thought there was that the user did not have sufficient permissions to patch the executable.

3.  This is going to depend on the specs of the system to a large extent, as well as what's in the city, and how big your Plugins folder is.  I'm on a 4-year-old desktop with moderate specs (AMD Ryzen 7 1700, 16GB RAM), and about a 6GB Plugins folder, and haven't had it take more than 2-3 minutes.  If you load up SC4 the first time after booting up your computer, that's when the peak slowness will occur.  That first city you load up--regardless of what city it is, or what's in it--it's going to be slow.  If you open any subsequent cities during that session with the game, or close the game and reopen it at any point on that session with your computer, it should not be as slow, because your system has some of the heavy lifting already done.

Love NAM, but just did a new install 

 

Why do I have brown boxes on the regular passenger train station? What dependencies does NAM use?

Make sure you have JAVA installed. Without Java the NAM installer does not start

Really happy with this mod so far. I was just wondering if a toll booth/RFID toll bypass lanes would be added for simulating turnpikes other then using the vanilla toll booth, unfortunately the vanilla tollbooths are a rather unfortunate bottleneck at times.

Also will Ploppable full interchange for the various freeway sizes be added in far future?

@Gully911, thanks for the kind words!  To answer your questions:

Toll booths/RFID: Surprisingly, toll booths aren't an area where we've really done much.  Aside from some stat fixes on the Maxis ones, there aren't any added in the mod, partly a vestigial remnant of the era when we didn't allow Lot-based transit items (including Toll Booths and Stations) into the NAM.  We've had some preliminary discussions internally about rectifying this gap.

Interchanges: If you're referring to the RealHighway (RHW) system, there has long been a plan to add FLEX-based full interchanges, known as QuickChange Xpress (QCX), for those networks.  It's suffered some setbacks over the years, but finally getting an initial phase of it in place is a top developmental priority for me right now.

i need some help, i have downloaded the mod, unzipped it into a folder. when i double click NetworkAddonMod_Setup_Version44.bat the installation window shows that the 4GB patch was successfully applied press any key to continue. but when i press the "Enter" key, the installation window immediately get closed and the installation process stopped. i don't know why this is happening, i have tried to install NAM after shutting down my anti-virus software, the same problem persisted.

Thank you that solved my problem. when i was reading the installation guide, i didn't see a line stating potential user need to have Java installed as a pre-requisite. Maybe should add a note in there just in case.

Good news, what you're suggesting already exists, you must have overlooked it, because it's right here on this page under requirements, and also says in the documentation that comes with the download.

Before all, I followed the instructions and installed the 4GB Patch and the Java Runtime Environment. Then proceed to next step NetworkAddonMod_Setup Version 44.bat for windows and then that message ''The 4gb_patch.exe file was not found in this folder.'' How could it be, if I patched to the game folder ?

Make sure you unzip the contents of NetworkAddonMod_Setup_Version44.zip into a folder.  If you try to run the .bat while it's still inside the .zip file, the 4GB Patch process will fail every time, even if it looks like it's done something (i.e. modified the file dates).

If you managed to manually apply the 4GB Patch without the .bat, you can then just run the .jar to install the NAM.  You'll know if you were successful or not if you're running the full version of the NAM Controller and the game doesn't CTD upon trying to load a city.

If you managed to manually apply the 4GB Patch without the .bat, you can then just run the .jar to install the NAM.  You'll know if you were successful or not if you're running the full version of the NAM Controller and the game doesn't CTD upon trying to load a city.

I decided to do all the steps again, deleting all files and installing again as clean setup. Now it worked.Thanks for answer and helped me out  =)

With the latest version of NAM, DBE with MHO stopped working for me:

Also noticed that RRW 7.5 changes MHO to MHW:

Please help me with a solution!

Those images suggest that you have some sort of conflict going on between MHO and MHW.  There could be any number of possible causes, including having a mix of files from different NAM versions, to file architecture issues with the mod itself. 

We've just redone a bunch of stuff on this end as part of the massive cleanup project ("NAM 44X") that we did before beginning NAM 45 development, so this should be fixed with our next release.

Hello! I am trying to use this. I installed OpenJavaJDK, and then tried installing through the bat file. I even ran as admin.

 

I get this error message:

I notice that it's trying to use my SQL server files, dragonica, as a lookup table. Why might this be?

The only way it could do that is if your Windows Registry entry for SimCity 4 is somehow instead referring to your SQL server files.  The .bat file does a look up of the Windows Registry to (a) find if the user is on 64-bit Windows (if they have a WOW6432Node section), and (b) to then locate the user's SimCity 4 installation (the key is generally Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Maxis\SimCity 4 on 64-bit Windows), such that the game's executable can have the 4GB Patch automatically applied to it.

Check the registry, and/or manually apply the 4GB Patch to the game's executable.  Here is more information on the 4GB Patch from its creator, NTCore.

The mod will not install. i followed the steps and it simply doesnt work. Ive modded alot of games in my time but the installation guide to this is alot of word salad.Just make simple bullet points of what to do and in what order

YOU ARE NOT MAXIS

 

Lets stop the pretense with the huge document that comes with the NAM and just keep it simple. Youve forgotten the most vital part of modding and thats making the installation process the focus of the whole thing and MAKE IT CLEAR and cut out all the guff that tries to look like its the official manuel to SimCity 4.

If the mod is not installed it means that you have not installed JAVA. In the installation package there is the java installer. Once you have done this procedure try to run the NAM installer. The instructions have been detailed as NAM is a complex mod and all the procedures you need to do are indicated as your problem can be solved easily without making unnecessary complaints.

We are willing to help you with getting the NAM to work, but please be courteous and constructive. The tone of your reply comes across very disrespectful to the numerous people and volunteers, who invest countless hours into making SC4 more enjoyable for many. A lot of this requires patience and working through problems. Remember how none of us are paid any salary for contributing to the community. We're not competing with what Maxis made, but building on their excellent sturdy foundation.

This is all voluntary in freely dedicating time to make the game better for all, now almost 20 years and counting.

In your next reply, we encourage you to respectfully keep this in mind.
