This is how I would do it: FF hex is 255 decimal, including 0 this gives 256 possible values for the XOR (assuming it is always 2 hex digits). So write a little program to XOR the binary file with all possible 256 values. This will produce 256 output files (include the XOR value in the file name), which you can then search across for a known string e.g.,ReadingFooter. The name of the matching file will contain the correct XOR value.
It sounds complicated, but it is quite a simple program to write, and would probably only take 5-10 minutes to run. I would write it myself but have not bothered as someone always supplies the XOR value here.
