Yes I have full MAME set (0.226 Merged) , and used mame importer. If I import all clones as separate It finds all clones, then I can use consolidate roms, but it is still not consolidate all. Now I have used FBANeo romset and imported as roms with consolidate option, it seems to do the trick for most games, but I can do the rest manual. So now my question is, I have lots of clones like on the picture
How to chose default colone to run for LB and BP?
And another question, can I change retroarch core per game?
