Just throwing this out there ....

ZoZo's fine port of HxC manager is from 2013 and is - as far as I understand - a port of the first release of the program from the developers of the HxC.

However, at least on the CPC there has been a number of updates since then and the latest version is from 2017 and should be much more stable and versatile.
