I built a full arcade using PiPlay about a year ago. I was considering switching to Pi2 and RetroPie and had a few questions.
1) Any reason to think I will have a problem with the wiring of my buttons to the GPIO? My current setup uses a customized version of adafruit’s retrogame.c code to handle two players (joystick + 6 buttons per player). I can’t imagine why I would but figured I’d ask.
2) Using the RetroPie UI can you show all games across all emulators without having to first choose an emulator?
