I just installed my first Pi 3 device and am noticing some issues. I ported over the ROMS from my laptop and am having the same delay and response issues w/ my USB controller. Makes gameplay really frustrating. I am considering purchasing a new controller. I don’t recall having this problem before I took the controller in my luggage on my last trip. Framerate compared to some original games also seems different. The board as it stands gets warm, but doesn’t get hot. If I overclock the device, I am sure I will have to implement a fan or some other cooling system. Although, it’s a nice alternative to some of the devices like the NES, SNES mini or the AtGames offerings, I am not too impressed so far… configuration and updates seem to take forever, while porting over Gigs of ROMS took seconds. I would update, and have to reboot twice before I see results. Even configuring the controller using emulationstation wouldn’t work until I rebooted two or three times… Maybe I just received a faulty board?
