Idk, I'm using my kickstarter Ouya as an emulator box right now. If the RetroN5 just dumps cartridges instead of reading them like original hardware did, I'd see no reason to change.
Nothing beats the original, though.
Me too dude, its my Neo Geo/N64/SNES all in one and im using a usb Saturn pad on it. I like the idea of a Retron5 but i cant justify buying one over the real thing.
