I've made the necessary modifications to am.xml to create a CurrentSetup.xml as per the one hosted by PhatNoise.
I've tested with Music Manager 2.30 and it doesn't appear to be complaining about the file and shows my configuration as being the firmware I chose.
Therefore when using the hack tools to Create a New DMS, or update firmware, the file CurrentSetup.xml will no be of the correct format. This does NOT require a modification to the hack tools application.
Hopefully someone can confirm in the next day or so if these changes work with PhatNoise Media Manager v3.92......
