just try to extract and seems that installer/uninstaller are broken, extract made with errors.
If then I try unpack MobiReader-impl.jar from installer, i got errors. If I try this with jar from uninstaller, it's ok. May be jar file is broken and so we have cutted pictures?
For extract rename *.bin to convert and run "./kindletool convert convert". Output will be convert.tar.gz file
Sorry for my ugly English
