NCX Decoding Puzzle
Well, I took a quick look at where the ncx file might be being stored, and it turns out that when an ncx file is added to the sources, you get three extra records added to the Mobipocket file.
Here's the source NCX file, along with the three added sections of the Mobipocket file (separated out into individual files).
I don't have time to properly decode the binary formats, but if anyone fancies a puzzle, here they are. The task is to work out how to reconstruct (as best as possible) the source ncx file from the compiled binary files.
