So i have a bartop arcade running retropie/attractmode with a raspberry pi 3. I am only running arcade games via mame for that nostalgia feel from when i was a little boy. So here is my problem, i have mame up and running and my bartop boots right to mame. But i also remember playing Dragon's Lair 1 & 2 and Space Ace. I have heard that there is a way but how can i make Daphne games show up in the mame games list and launch when i choose the games? I have seen it with done with windows, but how do i do it with retropie?
