I decided to give the nightlies a try to see how they were, but I can’t get past the help message the first time you run an emulator (or RGUI).
Despite manually assigning buttons on the input tab in the Android interface, none of the buttons on my controller would clear it, and the FireTV doesn’t have a touchscreen so I can’t tap it. I even tried plugging in a USB keyboard to see if I could use that to get past and no dice.
