There hasn't been any new SNES games released for the N3DS. The last one was Castlevania: Dracula X, which came out in North America on December 29, 2016 and Europe on January 26, 2017. Where the hell is Super Mario All-Stars, Super Mario RPG, Kirby Super Star, Kirby's Dream Land 3, ActRaiser, Gradius III, Harvest Moon, Wild Guns, and Pac-Attack? Some of those could at least be released, until the Switch launches.
