omg, it works!! thankyou!
and thankyou again, Frederick for the original code!
I've discovered a weird thing when changing header = infile.read(8) to
header = infile.read(4):
For some reason, the extracted png image is the exact same size as the
savegame archive (10.1 megs.) When reading 8byte
Don't seek to position 97. Seek to 96. You're off by one. That's why
there's the test for the header (which you removed).
Files (and Python strings for that matter) are 0-indexed. The first
character is 0, the second 1, and so on. If you want the 97th character,
you have to seek to position 96.
Hmm...I'm not sure exactly. One of the things I've read is that
sometimes stuff is compressed in a savegame file, but I don't know why
they'd do that with a png..
I have some code that does the exact same thing in php only I don't
understand php syntax and how they did it. Does it give any clues a

Well, I've been working on getting this code to work, and I think I
*almost* have it...
First, according to ghex, it seems the PNG starts at the 97th byte of
the file
infile = open("mysimcityfile.sc4", "rb")
infile.seek(97)
print (infile.read(4))
output:

Hi,
As a newbie to the language, I have no idea where to start..please bare
with me..
The simcity 4 savegame file has a png image stored at the hex location
0x80. What I want to extract it and create a file with the .png
extension in that directory.
Can somebody explain with a snippet of code ho
