When you download RA2 software you get a version called "Essentials"
If you are an L2 dealer you can update Essentials to Inclusive which adds a few more features such as being able to extract a file from the processor.

I agree with Mogul, I would want to extract what is there, even if I was going to redo everything. There might be some things hidden around the house you haven't seen, but they will be in the program for you to find.
