How to install KUAL and mods on KOA running 5.9.2.0.1?

I recently updated my KOA to 5.9.2.0.1 and the jailbreak survived. But as I tried to install KUAL using MrPI method I found it failed (open KUAL in the list of books and find it turns into a blank page)

And I searched a bit, it turns out that installing mods requires a modified .bin and use the update kindle option to install them.

But I can't find the modified .bin for linkfonts. So please tell me if I'm right and if I can install the linkfonts any other way.

Thanks a lot.
