Howto Extract PNG from binary file @ 0x80?

[flamesrock]

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 how I would accomplish
this? I've looked around but the information is too vague and I don't
know how to start.

-thanks in advance
