So it seems some that some mame cores in retropie see the yoke and some don't.  Unfortunately the ones that do have performance issues rendering the game unplayable for one reason or another. I seem to have Paperboy and Return of the Jedi up and running properly so I know the yoke works fine. Can anyone give me some help getting this working on the following games?

Hydra, Firefox, Spy Hunter, Star Wars, Empire Strikes Back, Roadblasters, Terminator 2, Revolution X, Operation Wolf, Operation Thunderbolt & S.T.U.N. Runner

I've tried pretty much all the mame cores available in retropie and have had little to no success getting these games setup properly. The cores I've tried are advmame, advmame .094, advmame 1.4, 2000, 2003, 2003 plus, 2010, 2015 & 2016
