Hi. Does anyone have a script or tool to unpack pcfile.dat and commentcount.dat from RTL Ski Jumping 2004?

 

My scrpit doesn't work: 

import os
import struct

def extract_packfile(pack_path, output_dir):
    if not os.path.exists(output_dir):
        os.makedirs(output_dir)
        
    print(f"Opening file: {pack_path}")
    
    with open(pack_path, 'rb') as f:
        # Read "PACK" magic header
        magic = f.read(4)
        if magic != b'PACK':
            print(f"ERROR: Not a valid PACK file! Header found: {magic}")
            return
            
        # Read version and file count (32-bit integers, Little-Endian)
        version = struct.unpack('<I', f.read(4))[0]
        file_count = struct.unpack('<I', f.read(4))[0]
        
        print(f"Archive version: {version}")
        print(f"Files to extract: {file_count}")
        print("-" * 50)
        
        files_metadata = []
        
        # Read File Allocation Table (FAT)
        for i in range(file_count):
            # File name takes exactly 64 bytes (0x40)
            name_bytes = f.read(64)
            # Decode name, stripping trailing null bytes (\x00)
            name = name_bytes.split(b'\x00')[0].decode('utf-8', errors='ignore').replace('\\', '/')
            
            # Read file offset and size
            offset = struct.unpack('<I', f.read(4))[0]
            size = struct.unpack('<I', f.read(4))[0]
            
            files_metadata.append((name, offset, size))
            
        # Extract files
        for name, offset, size in files_metadata:
            if size == 0:
                continue
                
            print(f"Extracting: {name} ({size} bytes)...")
            
            # Create directory structure if it doesn't exist
            full_output_path = os.path.join(output_dir, name)
            file_dir = os.path.dirname(full_output_path)
            if not os.path.exists(file_dir):
                os.makedirs(file_dir)
                
            # Seek to file position and read data
            f.seek(offset)
            file_data = f.read(size)
            
            # Write file to disk
            with open(full_output_path, 'wb') as out_file:
                out_file.write(file_data)
                
    print("-" * 50)
    print("Done! All files have been successfully extracted.")

if __name__ == "__main__":
    DATA_FILE = "packfile.dat"
    OUTPUT_FOLDER = "extracted_files"
    
    if os.path.exists(DATA_FILE):
        extract_packfile(DATA_FILE, OUTPUT_FOLDER)
    else:
        print(f"ERROR: Could not find '{DATA_FILE}' in this directory!")
        print("Please place this script inside the game folder next to packfile.dat.")

commentcount.rar

please upload the game executable

Ok, that's it

rtlsj04.rar

.... maybe upload the sister/TOC file (pcfile.dir)

Ok.

pcfile.dir.rar

Anybody can help me ?

I didn't get a notification for this for whatever reason but also this uses a different compression algo than the other RTL ski jumping games so be patient
