I'm interested in making a modern reader program for my Jailbroken Kindle 4; yes, I've tried koreader, it's very nice but it's not optimized for non-touch kindles and runs very slowly (and sometimes outright crashes) on this Kindle. Even if I could get the KDK, I would be looking at documentation via the Wayback Machine which might not have everything backed up.

But I goto koreader's Github repo and see it's done in Lua. And furthermore, I see that it uses a compiled version of luajit. So there has to be some access to those APIs beyond Java, right? I do know that the system is just Linux/X11, and I could use that to display, but there's also the buttons on this model and other features that I don't have information on how to use.

Am I not finding something, or has nobody documented how to do Kindle development without Java? By documentation, I mean a cohesive document, not just looking at the source code for koreader.
