For the time being it would seem that the history.dat format will still be generated and I can only assume that at some point in the future the move will be made to supporting only the xml format. The changes were made as of 0.227.

Thought I would make you aware, and maybe put in a feature request to support the new format. I am going to do some reading up on the changes to see if there is any help I can offer. I have linked below the orignally MAMEWorld forum topic for this item and linked the history.dat (now xml) for reference purposes.

Mame control file not found. You need to build the Mame main database using the context menu "Setup addon in the AML main window"
But I don't find such option there.
EDIT:
I found it, but I get an error:

EDIT2:
I had retroarch's mame and there I get the error. I changed to vanila mame and now I manage to start building the main database(some other options still give an error).

On the positive side, the All in One setup completes much quicker than AML 0.10.1 in Kodi 18.9.  Thanks Wintermute for the continued development and support.
