I'd seen the box for that "Over Lord" somewhere before, but never knew what it was.
Of course it's a Double Dragon 3 hack in PocketNES! Why wouldn't it be...
(Also, I love how on "Defender", they hacked the sprites into some weird unrecognizable thing that is Clearly Not A Ninja Turtle. And then, as the finishing touch...put a big honkin' Ninja Turtle screenshot on the PocketNES title screen.)
