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:

What's New 49 (rev1)   View Changelog


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

If I may be so bold, people are complaining about the load times, while I'm not dealing with 5 mintues or more, remember the first time you boot the game takes longer but boots way faster after a CTD, then after you load the first city tile, switching and loading another should take about half the time. Anyways, one thing I think everyone is failing to realize, it might take twice as long to load the game, but I can build way faster, I built a cool city of 60,000 people the other day in like 6 hours all together. Just with the draggable curves, I dont have to prep, lay, cut, put in curves, then fillers around the curves. I prep, but also get the pattern down too, drag the road, it curves as I drag and the new draggable curves conform to sidewalk mods beautifully (They just need a draggable short 90 degree and they have them all! Yeah!) They've redeveloped the speed of access, and basic functionality. Project Symphony rings true with how everything is blending and cities are becoming alive, and not chopped up by contrasting textures, looking like Frankenstien's Monster, bwahahaha!! This is good high quality, and very noble! work. I'm having CTD's during saves, and almost every exit to region, but I just can't let go of this new NAM. It's too smooth and fun!! Great job guys!! 110%, 3 thumbs up, 6/5 stars...

Thank you very much...

There are many new features and updates that I love; however, it takes a very long time for any of my cities to load and I find the new system of turning lanes unusable and annoying. Is there anyway to revert back to the default turning lanes for the older NAM versions?

I have been playing sc4 since it came out in 03' and just like a crack addict i can't seem to put down the "pipe" forever. It's nice to see that simtropolis is still up and running as it has been for so long now :) This game would never be the same without the NAM.

Since i upgraded from  NAM v30 to 31 my load times for empty cities changed from reasonable 30s - 60s to 5min and more, the game slowed down considerably  and i get a awful lot CTDs & BSoDs.

So I'm going back to v30.

 

 

JFYI:

I'm running SC4 Deluxe v640 on WinXP SP3, currently without any other Mods installed.

After I've installed this version of NAM, building single track rail and NWM roads bring the game to a temporary freeze for several minutes. Did anyone encountered such a problem?

Installation error, fail to copy and extract files. Any help? I have not installed this mod before, which means it is a fresh installation.

I have an annoying little problem with a texture. The sides of my Elevated Rail and Monorail tracks have these bright alternating color patterns, as if there were giant rope lights strung along the sides. It looks like something that might result from lacking some texture...any idea what the cause might be and how to fix it?

 

Ya, me too have this problem.

I was in the mood to play Simcity 4 deluxe once again. I installed the game and patched it with the latest patch. Game worked fine. When I install the NAM mod the game will start, however; opening a city freezes the game. Not sure what the issue could be.

Where did the hole diggers go??

Other than not being able to find them the latest update is AWESOME

Regarding the red-and-green squares on the El-Rail--just deselect the Alternate El-Rail set or install the "Cool Blue" texture set if you are intending to use that feature.


As far as crashing/CTD reports go, it's because the RUL2 file in the controller expanded to 2.12 million lines of code--a lot of systems have difficulty running that.  We're shrinking it down for NAM 31.1.

Having issues with the new version. Takes cities too long to load. After loading, the scrolling on the game is very slow, about 3-5 minutes later crashes to desktop, without having a chance to build anything. Just simply moving the mouse ctd. I can't find the older version to download either. It's ruining my playing experience.

I lost my left hand turn lanes and arrows.  Did I miss a box to turn that on?

 

Are you referring to turn lanes on Road x Road intersections?  If so, they aren't constructed automatically anymore--that functionality was getting in the way of the new Fractional Angle Roads and the Network Widening Mod.  Plop a Rail tile directly over the intersection where you want turn lanes--it'll convert.

 

 

How to delete it? 

I've installed it and game freezes while loading city.

 

Just run the uninstaller.

We are aware of this issue.  Your computer sounds as if it is unable to handle the Controller in NAM 31 (Intel Core i7 Sandy Bridge systems seem to have the most difficulty).  We generally discontinue old versions immediately after updates, but we've left NAM 30 up for the time being at ModDB.  The NAM 31.1 release will shrink the controller, which should minimize the potential for crashing.

 

Please note that we will not be providing any technical support to NAM 30 (or earlier) users.

The High Speed Rail System does not work, there are no trains departing nor leaving and on top of this, when going into vehicle driving mode, trains dissapear as they enter/leave the station and sometimes freezes the game. Please fix this issue. so far 6/10.

I've just tested it, and I cannot replicate your issues.  As far as trains departing/leaving, you need to have a certain amount of traffic (usually >200 passengers regularly on a given stretch) before you really see many train automata.

 

 

how comes its not giving me the option of Left hand drive? im new to this and have just installed SimCity 4. thatnks

 

The NAM does not change drive side, and the installer will select the appropriate files for whatever drive side your game uses.  In the past, you had the option of installing support for LHD versions of the game, though this did not change the drive side of the game, to some users' confusion.

 

To change drive sides, you need to edit the registry.
