Thanks for the help so far. I was able to have AdvanceMAME output an XML file thru the terminal. I found advmame’s gamelist.xml but it only seems to have the games that were recently played and looks nothing like advmame’s XML.:
<path>./(name of ZIP)</path>
Is there another XML file emulationstation uses? or is there a way to implement the advmame XML file somewhere?
EDIT: found this perl script that sorta helps:
gets close to auditing the ROM’s but not all.
