I have been doing some experimenting with the new version of Kindle for PC that supports KFX.
Many books published on Amazon still do not support enhanced typesetting and so are delivered to K4PC in KF8 (or MOBI) format.
I have also found that some books that are delivered to a Kindle device in KFX are delivered in KF8 format to K4PC. I have seen this in comics and other assorted books. It is likely that the K4PC implementation is missing some KFX features resulting in fall back to KF8.
This seems good, but there is a problem. Many of those books are delivered in a split format with text in the .azw file and images in a .azw.res file. This appears to be the same as the .azw3/.azw6 split sometimes seen on e-ink devices. As far as I know there isn't any existing software that can combine these into a single working file.
Even if KFX is cracked the books delivered in split KF8 format will still need to be dealt with.
