Simcity 4 Deluxe Edition V11640 Patch Link
The v1.1.640 patch includes SafeDisc DRM, which Microsoft disabled starting with Windows 10 (due to security vulnerabilities). As a result:
Since Maxis/EA no longer hosts this patch officially, the community has preserved it. Below are the two safest locations to download SC4Update4bat.exe (the official filename for the v11640 patch):
Option 1: The SC4 Devotion LEX (Community Gold Standard)
Option 2: Archive.org (The Legacy Vault)
Option 3: The Official (but hidden) EA FTP Archive (Use with caution as FTP links change)
Do not use "Patch 641" unless you are on GOG. Patch 641 breaks the BAT (Building Architect Tool) and several mod launchers. Stick to 640 for Steam/Retail/CD versions.
Even with v11640, Windows will limit the game to 2GB of RAM. Download the "4GB Patch" (by NTCore). Run it, select your SimCity 4.exe, and patch it. This allows the game to use 4GB of RAM—critical for large cities.

In the world of SimCity 4 Deluxe , version 1.1.640 (often called the "BAT Update" or "Nightlighting Patch") is the legendary milestone that brought light to the darkness—literally.
For years, mayors who built their cities from the original CD-ROMs faced a frustrating mystery: while their skyscrapers looked great by day, custom-made buildings from the community would stay pitch-black at night. This patch was the official fix from Maxis, enabling those intricate "nightlighting" effects to glow as intended. The Patching "Quest"
Getting to 1.1.640 is a two-step journey for those using the physical disc version: The v1
The Foundation: You must first apply the EP1 Update (Version 1.1.638). Without this core expansion patch, the nightlighting update will fail.
The Glow-Up: Once the EP1 fix is in place, you apply the Update4BAT executable to reach version 1.1.640. Where to Find the Files
Since the original Maxis site is long gone, the community has preserved these essential files on veteran fan sites:
Simtropolis Maxis Files: A reliable vault for both the EP1 (638) and BAT (640) updates.
SC4 Devotion: Another cornerstone site where the 640 patch is hosted in the "EA Support" or "BAT" section. The Modern Shortcut
If you are playing on a modern digital platform like Steam or GOG, you can skip the manual patching entirely. These versions typically come pre-patched to v1.1.641, which includes everything from the 640 update and more. I can't install EP1 Update 1 patcher for SimCity 4 Deluxe.
The primary feature of the SimCity 4 Deluxe Edition v1.1.640.0 patch is the addition of nitelighting support for custom buildings. Without this update, custom landmarks or buildings created with the Building Architect Tool (BAT) often appear completely dark at night. Key Details & Patch Link Option 2: Archive
Nightlights Support: This is often referred to as the "BAT/nightlight update". It allows custom-made buildings to display their designated night textures correctly.
Mod Compatibility: Many major mods, such as the Network Addon Mod (NAM), require the game to be patched to at least v1.1.638.0 to function, though v1.1.640.0 is the standard for full custom content support.
Patch Link: You can download the official update from community archives like SC4Evermore or Simtropolis. How to Check Your Version
To verify your current version, find your SimCity 4.exe file, right-click it, select Properties, and check the Details tab. v1.1.610/613: Unpatched (original CD version). v1.1.638: Partial patch (includes the "EP1 Update"). v1.1.640: Fully patched for custom nightlights.
v1.1.641: The digital version sold on Steam and GOG, which usually comes pre-patched.
