And if I check off the box (e.g. for Sect. 1) and try a 'save' then I get an empty (0 byte) file.

Of course, because you've got nothing loaded. You must first OPEN an RGN or GCD file to see it's various BIN files. To do that either drag the file onto RGN_Tool.exe OR open RGN_Tool and drag and drop the file onto the GUI's 'File Drop Zone' OR open RGN_Tool and press 'File' > 'Open RGN/GCD' [or press the big 'Folder' Icon below 'File' button] then browse to the required firmware file. When you have the fw file open, press the 'Save' button on the first section holding 'boot.bin' and save it as 'Ldr.bin' to use with your text command. [More than one way to skin a cat ].

If you're still stuck, here it is anyway. Extract the rar file to find Ldr.bin.
