Hi everyone, I am trying to emulate Bandai Super Vision 8000. I managed to run this system on mame and mess thru launchbox by typing command line "sv8000 -cart". However I cannot run Bandai Super Vision 8000 or even Fairchild Channel F (although FreeChaF core does the trick) on Retroarch with mess2015, ume2015 mame cores. Would you please help me if there is any way to run first and second generation games on Retroarch with mess2015, ume2015 or mame core?
