Hacked Up Reader for Kindle Touch

HackedUpReader is a CoolReader 3 port for the Kindle Touch using the X11 gui of the CoolReader project, minimally adapted for the touch interface.

It is only meant to act as a temporary solution to get a ePub reader for the Kindle Touch.

HackedUpReader is by no means thought for general usage. Currently you need to be familiar with accessing your Kindle Touch and starting programs from the command line to use it.

What works:

  • reading e-books
  • setting options
  • battery display

What doesn't work:

  • a lot that needs keyboard input
  • selecting other e-books
  • advanced features like bookmarking because of missing keyboard
  • some fonts lead to a crash (none of the default fonts on the Touch)
  • no automatic screen refresh for removing e-ink artifacts

Installation and running

Extract the archive into your Kindle Touch user data directory.

ssh into your Kindle Touch and start it with:

/mnt/us/cr3xcb/bin/cr3 /mnt/us/path/to/your/ebook.epub &

Because of some hard coded paths HackedUpReader must be in the /mnt/us/cr3xcb directory.


When in the main screen, touching in the lower half of the screen opens the next page, touching in the upper half opens the previous page. Touching the top bar will open the menu.

When in the menu, touching the top bar acts as 'Ok', touching the bottom bar on the left side will open the previous menu page, touching the right side will open the next menu page if there are any.

Touching numbered sections in the menu will select them or open any existing sub menu.

You need to set the correct values for your cross-compilation environment in tools/toolchain-arm-linux-gnueabi.cmake for the cmake variables CMAKE_C_COMPILER, CMAKE_CXX_COMPILER, CMAKE_STRIP and CMAKE_FIND_ROOT_PATH.

In the following command, "/kindle_development" should be the same directory as CMAKE_FIND_ROOT_PATH.

$ mkdir build; cd build
$ env PKG_CONFIG_LIBDIR=/kindle_development_dir/lib/pkgconfig \
   cmake \
    -DCMAKE_PREFIX_PATH=/kindle_development_dir \
    -DCMAKE_TOOLCHAIN_FILE=`pwd`/../tools/toolchain-arm-linux-gnueabi.cmake ..
$ make && make install

Who are you and why are you doing this?

I'm Patric Mueller and I'm doing this because - contrary to Amazon who's manufacturing a great piece of hardware but is equipping it with inferior software - I like my e-books kerned, hyphenated and justified.

Something went wrong with that request. Please try again.
