Adjust ONLY right or left margin - Page 2

I'm in the same boat as yascwartz - cracked screen, can't use the bottom 1/3 of the display, no experience jailbreaking or hacking a kindle. My device is with a 5-way controller.

Can anybody help how to implement this scroller?

The first step is to determine what model Kindle you have.
Compare the first 4 characters of the Kindle's serial number with this chart:

I did not look at your code yet, but the easiest way to rotate the screen sidways is just to shift the framebuffer copy a few bytes either way (up to a line width if needed) when rewriting to the framebuffer. Shifting multiples of the virtual line width (may be a little wider than what you see on the screen) obviously rotates the screen vertically. In other words, just use my code but do not multiply by the line width...

It will be interesting to see how simple (or complex) the final solution became in my absence...

How can I use this kindlet to shift the screen to the right just a couple of pixels? (I don't know how many, maybe 2 or 3 is enough.)
Many thanks in advance.
