-zenutils is a collection of utilities for working with firmwares of the Creative Zen range.
-
-The utilities are split into 3 categories:
-1) update_*
- Operates on the Creative firmware updater executable.
-2) firmware_*
- Operates on the Creative firmware archive.
-3) zen_crypt
- Operates on the parts of the firmware archive which requires cryptography.
-
-
-General usage:
---------------
-A typical use scenario would be: download the firmware updater and run
- update_extract on it to obtain the firmware archive which it contains.
-Run firmware_extract on the firmware archive to obtain the files
- which the firmware archive contains and a make file that can later be used
- to create a new firmware archive. Edit* the extracted files of
- interest and optionally the associated make file. Create a new firmware
- archive by running firmware_make. If a NULL entry is present in the firmware
- then it's signature has to be updated running zen_crypt. If on windows, you
- can use update_patch to write your newly created firmware archive to the
- updater executable which you originally extracted it from. The new updater
- will update your player with the modifications you've made.
-
-* If you're creating or editing executable code, such as the CENC or ŠTL entries,
-you'll need to use zen_crypt to decrypt and/or encrypt them.
-In addition, executable code on some players that use the ŠTL entries also needs
- to be signed using zen_crypt, prior to encrypting them.
-Encrypting FBOOT and FRESC is not supported, as these contain the executable
- code that makes up the critical Rescue Mode software, contained in flash.
-As opposed to CENC and ŠTL which ultimately ends up being stored in the players
- filesystem as a file named Jukebox2.jrm.
-
-
-Important:
-----------
-The only entries required in a firmware archive is CINF and if present, NULL.
-Including either FBOOT, FRESC or EXT0 in your firmware archive is not advised,
- the first two are required for the Rescue Mode software operation and EXT0 is
- unknown, but given that it's contents is sent to an internal device named mcu0,
- the consequences of failure could be fatal to your player.
-
-
-Supported players:
-------------------
-zen_crypt supports signing, verification, decryption and encryption on the
- following Creative Zen players:
- Vision:M (default if no player is specified)
- Vision W
- Micro
- MicroPhoto
- Sleek
- SleekPhoto
- Touch
- Xtra
-
-The other utilities are not player specific and may work on players not listed.
-Although the Vision:M is the only player I've fully tested.
-
-
-Building the sources:
----------------------
-The source code uses the CMake (www.cmake.org) build system.
-Once you've installed CMake, you'll need to run it to produce make files for
- your system. I would recommend producing the make files within in the 'build'
- directory of this package. Which can be done by typing:
- zenutils\build\>cmake -g "Visual Studio 8 2005" ..
- (for msvc8 on windows)
- or:
- ~zenutils/build/$ cmake -g "Unix Makefiles" ..
- (for various 'nixes)
-The windows example will produce a solution file for msvc8.
-The 'nix example will produce a makefile which can be built using make.
-
-The executables will be placed within the 'bin' directory, once built.
