# 📋 RR3 Asset Manifests
|
|
|
|
## Overview
|
|
|
|
These manifest files were extracted from the Real Racing 3 APK (v12.6.0 or similar). They contain the complete list of game assets that need to be downloaded from EA's CDN servers.
|
|
|
|
## Manifest Format
|
|
|
|
Each manifest file contains one asset per line with the following format:
|
|
|
|
```
|
|
/path/to/asset.ext<TAB>md5hash<TAB>compressed_size<TAB>uncompressed_size
|
|
```
|
|
|
|
**Example:**
|
|
```
|
|
/data/events.dat.nct 0a21c68abefbfcac00e7387f025e8012 14461497 14461497
|
|
```
|
|
|
|
### Fields:
|
|
- **Path**: Asset file path (relative to CDN root)
|
|
- **MD5**: MD5 checksum for integrity verification
|
|
- **Compressed Size**: Size in bytes when compressed
|
|
- **Uncompressed Size**: Size in bytes when decompressed
|
|
|
|

|
## Usage for Asset Preservation
|
|
|
|
### Step 1: Parse Manifest
|
|
```csharp
|
|
var lines = File.ReadAllLines("asset_list_base.txt");
|
|
foreach (var line in lines)
|
|
{
|
|
var parts = line.Split('\t');
|
|
var path = parts[0];
|
|
var md5 = parts[1];
|
|
var compressedSize = int.Parse(parts[2]);
|
|
var uncompressedSize = int.Parse(parts[3]);
|
|
|
|
// Download from: https://cdn-rr3.ea.com{path}
|
|
// Verify with MD5 hash
|
|
}
|
|
```
|
|
|
|
### Step 2: Download from EA CDN
|
|
The base URL for EA's CDN is typically:
|
|
```
|
|
https://cdn-rr3.ea.com
|
|
```
|
|
|
|
Full asset URL would be:
|
|
```
|
|
https://cdn-rr3.ea.com/data/events.dat.nct
|
|
```
|
|
|
|
### Step 3: Verify Integrity
|
|
After downloading, calculate MD5 and compare with manifest:
|
|
```csharp
|
|
using var md5 = MD5.Create();
|
|
using var stream = File.OpenRead(assetPath);
|
|
var hash = BitConverter.ToString(md5.ComputeHash(stream))
|
|
.Replace("-", "")
|
|
.ToLower();
|
|
|
|
if (hash == expectedMd5)
|
|
{
|
|
// Asset valid!
|
|
}
|
|
```
|
|
|
|
## Critical Assets
|
|
|
|
### Highest Priority (Game Won't Work Without These):
|
|
1. `/data/events.dat.nct` (14.4 MB) - All race events
|
|
2. `/data/jobs.bin.nct` (3.5 MB) - Job system
|
|
3. `/data/championships.bin.nct` (157 KB) - Championships
|
|
4. `/camTweaks.dat` (131 KB) - Camera configurations
|
|
5. `/data/gtlt.bin.nct` (688 KB) - Core game logic tables
|
|
|
|
### High Priority (Major Features):
|
|
- Formula 1 assets (17 KB manifest = ~500+ MB actual data)
|
|
- Base GUI assets (game menus)
|
|
- Audio base (engine sounds)
|
|
|
|
### Medium Priority (Enhanced Experience):
|
|
- Track-specific assets
|
|
- Car liveries
|
|
- Additional racing series
|
|
|
|
## Asset Statistics
|
|
|
|
Based on the manifests extracted:
|
|
|
|
- **Total Manifest Files**: 1,236 files
|
|
- **Car Groups**: ~25 racing series
|
|
- **Seasons**: 5 seasons of content
|
|
- **Estimated Total Assets**: 10,000+ individual files
|
|
- **Estimated Total Size**: 2-5 GB when fully downloaded
|
|
|
|
## Implementation Plan
|
|
|
|
### Phase 1: Automatic Download (While EA Servers Active)
|
|
1. Parse manifests on server startup
|
|
2. Create database entries for all assets
|
|
3. On first request, proxy to EA CDN
|
|
4. Cache locally and serve
|
|
5. Verify MD5 integrity
|
|
|
|
### Phase 2: Manual Upload (After EA Shutdown)
|
|
1. Community members share their cached game data
|
|
2. Upload via web panel
|
|
3. Verify MD5 matches manifest
|
|
4. Share with all players
|
|
|
|
### Phase 3: Complete Preservation
|
|
1. All critical assets cached
|
|
2. Game fully playable offline
|
|
3. Community-hosted forever!
|
|
|
|

|
## Next Steps
|
|
|
|
1. Implement `AssetsController` with manifest parsing
|
|
2. Add automatic CDN proxying
|
|
3. Create web UI for asset management
|
|
4. Start caching critical assets
|
|
5. Share with community!
