retrieve source for py2exe application

[JustinEzequiel]

Greetings all,

We're trying to retrieve the code for an old python 2.4 program that was converted into a single-file executable using py2exe.
Programmer left without updating the files in SVN.

Using Seven Zip, I was able to retrieve from the .EXE file the *.pyo files for the imported modules.
(The main script however is not so easily retrieved.)

These .PYO files convert easily back to the .PY source using easypythondecompiler.

Using resourcesviewer, I am able to retrieve what I thought was the main script.

However, easypythondecompiler complains with "Invalid pyc/pyo file - Magic value mismatch!"
leading me to think I "retrieved" the main script incorrectly.

Do you have any idea that may help?

getting closer... following the code at build_exe.py of the py2exe package I got the following

import inspect
import marshal

p = r"C:\Users\justin\Desktop\processdownloadedfiles_pythonscript_1.bin"
f = open(p, 'rb')
s = f.read()
f.close()

o = marshal.loads(s[17:-2])
print o
code = o[-1]
print dir(code)

x = marshal.dumps(code)
print len(x)
pp = r"C:\Users\justin\Desktop\processdownloadedfiles.pyc"
f = open(pp, 'wb')
f.write(x)
f.close()

however, easypythondecompiler still complains with the same error.
now to figure out how to turn a code object (see code variable above) back to source or to a proper .PYC file.
