While this post is not related to the 'Merdeka' story, it does share how I built the 'Merdeka' e-book in a format that now (hopefully) allows NCX functionality on a Kindle. It is aimed at other authors trying to get their self-published e-books into a Kindle ready format.
This advice will only work for you if you have built your manuscript in MS Word (and saved it as a Word 97-2003 document) and also if you are using MobiPocket creator to create the PRC file for your e-book. It is not my intention to re-invent the wheel and I would like to acknowledge Huw Collinbourne of 'Dark Neon', and Araby Greene of 'CJs Easy As Pie Kindle Tutorials'.
