✅ Product Catalog: Item catalog and categories (3 endpoints)
✅ DRM/Purchases: Nonce, purchase verification (3 endpoints)
✅ Analytics: Event tracking (2 endpoints)

🔍 Protocol Analysis Findings

Communication Architecture

[Real Racing 3 APK]
    ↓ HTTPS (HttpURLConnection)
    ↓ Custom Headers (EAM-SESSION, EAM-USER-ID)
[EA Synergy Director] → https://syn-dir.sn.eamobile.com
    ↓ Service Routing
[Specialized APIs]
    ├─ synergy.product (Catalog)
    ├─ synergy.drm (Purchases)
    ├─ synergy.user (User Management)
    └─ synergy.tracking (Analytics)

Key Technical Details

  • HTTP Client: Standard Java HttpURLConnection
  • SSL/TLS: Custom certificate validation (CloudcellTrustManager)
  • Callbacks: Native JNI for streaming responses
  • Format: JSON for API, Protocol Buffers for ads
  • Headers: EAM-SESSION, EAM-USER-ID, EA-SELL-ID, SDK-VERSION
  • Session: UUID-based, 24-hour expiry

🚀 How to Use

Quick Start (3 Steps)

1. Build & Run Server:

cd E:\rr3\RR3CommunityServer\RR3CommunityServer
dotnet run

2. Redirect Traffic: Add to hosts file:

127.0.0.1 syn-dir.sn.eamobile.com

3. Launch Game: Real Racing 3 will now connect to your local server!

✨ Server Capabilities

✅ Implemented Features

  • Device Registration - Auto-generate device IDs
  • User Management - Create/validate Synergy IDs
  • Session Tracking - UUID-based sessions
  • Product Catalog - Serve item lists and categories
  • Purchase Verification - Accept and record purchases (community mode)
  • DRM Nonce Generation - Provide security tokens
  • Analytics Logging - Record events (optional)
  • Service Discovery - Direct game to correct endpoints

🎯 Use Cases

  1. Offline Play - No internet required
  2. LAN Multiplayer - Local network gaming
  3. Game Preservation - Keep playing after servers shut down
  4. Content Modding - Customize catalog items
  5. Educational - Learn client-server architecture

📊 Technical Architecture

Tech Stack

Component Technology
Runtime .NET 8.0+
Web Framework ASP.NET Core
Database SQLite
ORM Entity Framework Core
API Docs Swagger/OpenAPI

Database Schema

  • Devices - Device registrations
  • Users - Synergy user accounts
  • Sessions - Active sessions with expiry
  • Purchases - Purchase records
  • CatalogItems - Available items (seeded)

Middleware Pipeline

  1. SynergyHeadersMiddleware - Extract/log EA headers
  2. SessionValidationMiddleware - Validate sessions (lenient mode)
  3. Controllers - Process business logic
  4. Services - Database operations

🔐 Security Features

Implemented

  • ✅ HTTPS/SSL support
  • ✅ Session-based authentication
  • ✅ Device ID validation
  • ✅ Request logging for audit

Considerations

  • Lenient validation for community use
  • No payment processing (community/free mode)
  • All purchases auto-accepted for offline play
  • Swagger UI for testing (disable in production)

🌍 Cross-Platform Support

Build Commands

Windows (x64):

dotnet publish -c Release -r win-x64 --self-contained
