Thank you very much, I now understood evrything and thanx for telling all the commands (now I can create patches too...yippee)
Also, I compared the patched file and the original file, but I didn't find a line that said to extract "NFSS_arc.exe"...all I could find was a line that was added to unpack an "exe".
I have attached the differences between both patched and original files.
