Sorry for double post, but it has been quite a while, so I think it is warranted.
For those who for some reason updated to 2.8.0,
tool has been updated. Windows x86/x64 only, as usual. Untested, as also usual. No longer needs memory dump, but is more strictly bound to Kindle exe version. For people who still get old (KF8/7) books for whatever reason (I've heard reports that older purchases and some non-US comics download as KF8), you would need at least 1 device bound KFX book to get proper k4i.
Please post questions, if any, in the usual
place, not here. I may answer, though not immediately.
