@voljega I did initially, but ran into some issues. The one plus with Retropie was being able to force one of a dozen emulators for a specific game.
But I digress.
I found my reference set for the 078 roms and copied them back over to the MAME folder overwriting the ones I had generated from clear mame and it works much better now.
I do notice on some games the sound is staticy though with MAME. Not sure why that is yet.
