Actually, the initial efforts were the libnetmd project [2]. I started linux-minidisc
with Michael Karcher around 2009 from scratch to enable HiMD support for Linux and we
gained most of the information of the inner workings of HiMD and NetMD by reverse-
engineering "HiMD Music Transfer for Mac" and "Sony SonicStage". There was no existing
usable documentation on how HiMD and the interesting parts of NetMD worked when we
started the project. That's why we were the first project to support actual transfers
to and from HiMD and to NetMD.

At some point, we decided we should merge our codebase with the libnetmd project and
extend libnetmd with the NetMD functionality we had in the Python NetMD code. So
we ported the NetMD Python code to C code with the help of a GSoC student during
Google's Summer of Code in 2011.
