They gave me an encoder and I'm trying to get it to decode as well. The code is written in Python, I tried to make some progress but I got stuck and can't get out of it:
this is the decoder code:
import sys, jsonfrom datetime import datetimedef run(): # Read input file input_file = sys.argv[2] output_file = sys.argv[3] # Print some useful information print('generate_map_bin by Icseon. Input file is > {0} <'.format(input_file)) try: # Load JSON file data = open(input_file,'r',encoding='windows-1252').read() # Output some useful information print("Got {0} map(s). Generating binary file and saving to {1} ...\n".format(len(data), output_file)) for instance in data: print("{0}\t{1}\t{2}\t{3}".format(instance['name'], instance['map'], instance['bgm'], instance['ui_picture']) .expandtabs(35)) # Construct map data block map_data = bytearray() for index, instance in enumerate(data): # Construct value array values = [ str(index) ] for key in instance.keys(): values.append(str(instance[key])) # Add value, followed by the 0x09 seperator for val_idx, value in enumerate(values): map_data.extend(value.decode('windows-1252', errors='replace')) # Add 0x09 to separate the values. Use 0x0D, 0x0A, 0x09 to signify the end of the value map_data.extend([0x09] if (val_idx + 1) < len(values) else [0x0D, 0x0A, 0x09]) # After we've added all the map data, we'll want to remove the last three bytes and replace them map_data = map_data[:-3] map_data.extend([0x0D, 0x3B, 0x09, 0x09, 0x09, 0x09, 0x09, 0x09, 0x09, 0x0D, 0x0A, 0x0D, 0x0A]) # Construct file header file_header = bytearray() file_header.extend([0xFE, 0xFF, 0xFF, 0xFF]) file_header.extend((65535 - len(map_data)).to_bytes(length=2, byteorder='little')) file_header.extend([0xFF, 0xFF]) # Combine the file header and map data result = bytearray() result.extend(file_header) result.extend(map_data) result.extend([0xFF, 0xFF, 0xFF, 0xFF]) # We'll have to xor the file now for i in range(len(result)): result[i] = result[i] ^ 0xFF open(output_file, 'wb').write(result) except Exception as e: print('An error occurred: ', e)The error I get:"An error occurred: 'charmap' codec can't decode byte 0x8f in position 12: character maps to "this is the encoder code:

The command with which it is executed is:python main.py generate_map_bin files/map_planet.bin "C:/Users/Rick/Desktop/new/map_planet.txt"
this is the file I want to decode:file.bin
I want your support to be able to finish the code, the idea is to make a decoder from the encoder
