Parsing Script

The following is a simple python script which reads and parses the GameMap.dat. Pass the filepath as the first arg & it will output each map ID alongside its path. Example: python3 gamemap_decode.py GameMap.dat

import struct, sys

with open(sys.argv[1], "rb") as f:
    count, = struct.unpack("<I", f.read(4)) # Little-Endian uint32 - Header (Record Count)
    for idx in range(count):
        map_id, name_len = struct.unpack("<II", f.read(8)) # Read ID & Length of Map Name
        name = f.read(name_len).decode("ascii") # Read the map name
        f.read(4) # Puzzle Size (value always 256), don't need to print it
        print(f"{map_id}: {name}")
