ETS2 Mod Sync

ETS2 Mod Sync is a lightweight GUI tool for synchronizing active mod lists between Euro Truck Simulator 2 profiles.

It allows you to select a source and target profile, preview their active mods, and copy the mod load order between profiles with a single click.

The application uses a native Rust decryptor for fast, cross-platform profile decryption — no external DLLs required.

✨ Features

• Simple and lightweight Qt (PySide6) GUI
• Preview active mods for both profiles
• One-click mod synchronization
• Supports XML mod lists
  • Import mods from XML
  • Export mods to XML
• Preserves mod load order
• Cross-platform

🖥️ Requirements

• Python 3.10+
• Rust toolchain (rustup) — required for first-time build
• Euro Truck Simulator 2 profiles (.sii files)

---

📦 Setup & Usage (Source Build)

This project is distributed as source-only and builds the native decryptor locally.

First-time setup

python -m venv .venv
.venv\Scripts\activate   # Windows
pip install maturin PySide6
cd decryptor
maturin develop

Run the application

From the project root:

python main.py

📄 Supported File Types

• .sii — ETS2 profile files
• .xml — Mod list export/import format

---

🧠 How It Works

• Profiles are decrypted in memory using a native Rust library.
• Active mods are parsed into an internal structure.
• Mod lists can be:
  • previewed
  • exported to XML
  • imported from XML
  • synchronized between profiles
• Only the final modified profile file is written to disk.

🧭 Planned Features

• Manual mod reordering
• Swapping Betwwen Profiles
• Drag and Drop Feature

---

🛠️ Built With

• Python
• PySide6 (Qt)
• Rust
• PyO3 + maturin
