@showstopper said in FBA Neo Romset help?:
For the HBMAME bit is there a list of the files that are required?
No, sorry, but apart from the few dkong hacks i added a few weeks ago (see https://retropie.org.uk/forum/topic/23549/donkey-kong-spooky-remix-in-retropie), i expect most of them to be also available from older FBNeo/FBAlpha romsets.
