About
SimCity Expansion provides a building-pack workflow for New-Simukraft, letting players import structures, convert them into SimuKraft-buildable buildings, organize and edit them, and share them in portable zip packs. It accepts vanilla structure-block .nbt files, Litematica .litematic projections, and Sponge or WorldEdit .schem files, merging multi-region Litematica builds and converting imports to the format SimuKraft can use. The manager lets players browse imports, packs, and installed buildings with previews and block-material lists, then search, sort, and batch-install structures. Its editor supports block placement, removal, replacement and brush painting, plus box selection, fill or hollow operations, copy and paste, rotation, mirroring, symmetry, undo and redo, and sliced or preset camera views. Players can also mark two corners in a world to capture a build as a blueprint, optionally preserving block-entity contents such as chest inventories and signs. Build packs organize buildings into residential, commercial, industry, public, and other categories; players can install or uninstall packs with tracked manifests and export installed buildings as shareable zips with optional icons and SimuKraft job or trade definitions. Create schematic files can appear among imports and be exported back to Create’s schematic library, allowing blueprints to be used with its schematic table and schematicannon without making Create a dependency. On dedicated servers, operators can use the /buildpack commands to manage packs and structures or capture regions, using the same conversion pipeline as the in-game manager.

Security
No harmful code found
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Forge 1.20.1.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.3 latest files: the newest file for each Minecraft version and loader. All 3 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.
- Looked for, not foundWe looked for these in the file and did not find them.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
We read its code without running it: it contacts no web address while you play.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 3 files, for recent Minecraft versions. See each file in Releases
- Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.Nothing declared about crash reports, usage data or advertisements.
AI
No sign so far that AI was used to make it
We looked for AI tools in its texts, files and images and found none.
We have not read its code history yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found14 of 22 changelogs read
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Nothing found
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Nothing found1 image read
- Code of the modThe code and files of the mod, read without running it: addresses of AI services, AI libraries, AI model files and a place for your own AI key.No AI service, AI library or AI model file177 code files read
