ScsUnitTypeCheckBypass

Bypass ETS2 / ATS Attribute Type Check (SCSUnitTypeBypass)

---

📦 Overview

ScsUnitTypeCheckIgnore/ScsUnitTypeCheckBypass is a telemetry plugin for Euro Truck Simulator 2 and American Truck Simulator that patches the game in-memory to bypass the SCS Unit Attribute Type Check.

This allows you to load modified or non-standard save files and unit data without triggering validation errors. Such as loading local mods from the bus_job_log

🖥 How It Works

• Hooks into the game via the official SCS Telemetry SDK.
• Locates the attribute type check jump instruction at runtime.
• Patches the instruction to disable strict type checking.
• Restores the original code safely on shutdown.

---

⚙️ Features

• Automatic detection of the check address at runtime (pattern scan).
• Clean patching using VirtualProtect for safe memory writes.
• No permanent modification to the game files.
• Support for ETS2 and ATS (eut2 and amtrucks).
• Support for TruckersMP
• Safe cleanup on plugin unload.

🧩 Plugin Usage

1. Drop the compiled DLL into your game's plugin folder:
   • ../steamapps/common/Euro Truck Simulator 2/bin/win_x64/plugins/
   • ../steamapps/common/American Truck Simulator/bin/win_x64/plugins/
2. Launch the game.
3. The plugin will:
   • Find the type check jump instruction.
   • Patch it.
   • Log the result to the game log.

✅ If successful, modified unit data will no longer be blocked by SCS's type checks.

📝 Important Notes

• Safe Unload: The plugin restores the original instruction when the game shuts down or the plugin is unloaded.
• Game Updates: Major game updates could change memory layouts. Always check compatibility after patches.
• Use Responsibly: Bypassing integrity checks may cause unintended behavior if data is heavily malformed.
