Sorry to bring this back, but the previous posts are partially helpful... I think...
I have not found a folder for cools in my AM, but am running Cools. Surely it is getting its config and layout from somewhere... yet nothing comes up in a search of my Pi... I want to edit the layout.nut file (to get rid of the rom name bar at bottom of screen) and wonder if just adding these folders to the layouts subfolder would work, or is it still going to get its config from wherever it gets it now?
