I've tried Calibre's ebook-convert utility to create AZW3 from EPUB and it works nicely. Here's what it looks like on a Kindle app (which should render the book the same as Amazon's e-Ink reader):Thanks @KS . EPUB would be great and with that Calibre can transform EPUB in MOBI file or AZW3.
I've spotted some minor formatting errors, but there should be no missing content (I'm 95% sure about that, but not fully certain without reading those 4000+ pages). I'll try to fix those in the coming week, and also make the repository public. I've attached a file that is a ZIP archive (the forum doesn't like attaching AZW3s) containing Kindle-compatible book format. Let me know if it works for you.
