If I may add - do yourself the pleasure, and use a standard usb Xbox 360 controller, otherwise you are in for a world of pain. I&#x27;ve tried a NES30 controller over bluetooth and after a week of trying different configurations nearly chucked the whole thing in a bin. Also some of the emulators are too slow to be usable, even on the Rpi 2, NES and SNES work absolutely fine, but MAME, N64 and Dreamcast are more like curiosities, very few games run at anything even close to full speed on them.
