Quoted from dkeruza:They use the core of Pinmame for emulation, so no big deal with Capcom or any other manufacturer, they could also run Stern roms if they add the code for it.
Is already done with pinmame / visual pinball.
When I was asking questions about the platform (maybe at Expo 2014?), they claimed to be using their own emulator core and not PinMAME. Same concept, but different code.
