# CS1 Datasync
[](https://github.com/bonsaibauer/CS1Datasync)
[](https://github.com/bonsaibauer/CS1Datasync/issues/new)
---
This mod lets you **automatically synchronize Mods and Assets between players** when playing Cities: Skylines (CS1).
That way, everyone has the same setup without manually copying files.
## Requirements
- **Hamachi** (or another VPN tool) to connect players’ PCs.
- **Harmony Mod** (mandatory, as many mods rely on it).
- All players need the **CS1 File Sync Mod** installed.
## How it works
- One player starts as the **Sender** → shares their installed Mods & Assets.
- Other players connect as **Receivers** → automatically download missing files.
- File transfer happens via **HTTP** directly from PC to PC.
The mod works with the **standard CS1 directories**:
- **Mods**: `%LOCALAPPDATA%\Colossal Order\Cities_Skylines\Addons\Mods`
- **Assets**: `%LOCALAPPDATA%\Colossal Order\Cities_Skylines\Addons\Assets`
- **Steam Workshop content**: is detected and synchronized too.
This means:
- You can sync Workshop mods/assets from a Steam user to someone **without Workshop access**.
- Perfect for multiplayer sessions where everyone needs the **exact same setup**.
## Setup
1. Start **Hamachi** and join the same virtual network.
2. In game:
- **Sender**: click *Start Sender*.
- **Receiver**: enter the **Sender’s Hamachi IP** and the **port** (default: `5005`).
3. Once you see *Connected* → click *Synchronize*.
4. The mod downloads and updates Mods & Assets automatically.

## Development
To build the mod yourself, you need:
- **.NET Framework 3.5 SDK**
- **MSBuild** (version `17.14.23+b0019275e` or newer)
Build command (run in the repo root):
```powershell
msbuild .\CS1.FileSync.csproj /p:Configuration=Release /t:Build
```
This will produce the compiled DLLs in the `bin\Release` folder.

`resources/lang/.json`.
- **Bug fixes / features**: open a pull request on GitHub.
- **Issues / feedback**: use the GitHub Issues section.

👉 In short: **Workshop → normal CS1 folders → shared with your friends**.
Great if not everyone uses the Steam Workshop, but you still want a synced set of Mods & Assets for multiplayer.
