I know of Double Dragon 1 2 and 3 in the arcades, and they've all seen they're share of 'ports' to home systems where sometimes the port is different, pretty different, and completely different from the arcades and then there is that mockary of a Double Dragon game Double Dragon V: The Shadow Falls, but I've yet to ever see a Double Dragon 4.

Was there one? say an obscure arcade title that never got ported, or inversely a home version only that was released very limitedly on only one or two consoles?
