 This software could help developing a Linux-software by analyzing the code of the transfer-program which is only about 1,5 Mbytes in binary. It appears that only the binary "HiMD Music Transfer" itself is necessary to communicate with the HiMD-Walkman, so the code to be analyzed is very few. The additional program "HiMD Monitor" is obviously only necessary to monitor whether a HiMD-Walkman is connected to the Mac and create a shortcut-link on the desktop to the transfer program once the walkman is connected.
-The software is a PPC-binary and contains much more functionality in its code that the GUI provides. For example, the code contains functions to format a HiMD or to encode ATRAC3-files, even though the GUI does not provide any functionality for that. Furthermore the code contains all debug-symbols and is not secured against disassembling like the Windows-software SonicStage. Loading the transfer-program into IDA Pro Advanced (with PPC-support) one gets huge information regarding the functionality of the software. Unfortunately there isn't any NetMD-functionality, which probably comes from the fact that NetMD uses it's own USB-protocol and thus requires also it's own driver.

 To the current knowledge, the code which interacts with the HiMD-filesystem (which resides in the folder "HMDHIFI" on the HiMD) is written in C++. Several classes represent the HiMDFileSystem, a HiMDFile, HiMDIo and more. They provide methods to format a HiMD, add/delete/rename tracks, create/delete folders etc. The actual filesystem which stores the audio is an image-file which is itself a FAT-filesystem with 2kb Sectorsize.

-The goal here is to fully understand the C++-code which contains the HiMD-functionality and reimplement the code in C/C++ again. That code would reside in a library called "libhimd" which then can be used from a simple Qt-based GUI to provide the functionality (and beyond :)) of "HiMD Transfer for Mac" on all platforms which support Qt.
