@sleve_mcdichael Thanks for clearing that up. So far everything is running like a dream. I need to sort out the 6 button layouts, but for the most part, with the exception of looking into how to make roms with CHD files work, the setup is pretty much done - with the exception of figuring out how to spawn multiple coin buttons on a RetroPie rig. However that's starting to shape up to be a potential second uint and housing's problem - presuming RetroPie even supports multiple coin slots at this point..
