I bring to you a little program that will put the Reader into white-on-black (inverse color) reading mode. Many people find this mode easier on the eyes and small text appears more legible. This change will affect everything, including books produced by RasterFarian. This change is, of course, reversible.
INSTRUCTIONS:
Extract the contents of the rar file to an SD card. The SD card can have books and music on it, just take care to preserve the file paths.
Pop the card into the Reader and you'll be given a menu. When you're done, you can exit and read your books. To change the mode again, take out the card and reinsert it (this will re-activate the menu).
The engine for running code and drawing menus is based on Igorsk's excellent PRS Flasher (simplified and cleaned up a bit). The program itself accomplishes what it does with a special ioctl call. The ioctl call was discovered while investigating eInk programming for the RasterReader (a viewer application that I'm writing for the Reader).
