This is an unofficial version of QHiMDTransfer currently not endorsed
by us. The reason is that it employs a secret key from Sony which may
not be disclosed.

This is correct. This version is capable of uploading tracks recorded
with other recorders than the MZ-RH1/MZ-M100/MZ-M200 which use a
particular simple encryption which does not need the aforementioned
secret key.

However, all other HiMD Walkman require QHiMDTransfer to have this
key as an upload is otherwise not possible. Furthermore, this key is
required for uploading all tracks downloaded with SonicStage onto HiMD
Walkman, regardless which model was used (even the aforementioned
models MZ-RH1/M100/M200 require this version in this case).

Those are all tracks store on a HiMD, hence the name
"QHiMDTransfer". If you want to transfer ATRAC-SP aka ATRAC-1 tracks
you need to use the NetMD utilities (netmdcli) which is currently
command line only.

Furthermore, please be aware that the MZ-RH1 and the technically
identical MZ-M200 are the only models capable of digital ATRAC-SP/-1
uploads (NetMD uploads). This is not a software limitation but a
limitation of the MiniDisc hardware. Other models allow analog upload
through NetMD only.

Cheers,

Adrian
