Is it possible to use the Retroarch GUI to run Odyssey2 games in MAME rather than o2em? I want to be able to have the the “cart1” and “cart2” options specified for specific games to be able to utilize the voice box emulation.
So far I haven’t even been able to get Retroarch to load an Odyssey 2 game in MAME from the console, so ANY help on this would be GREATLY appreciated.
