Nintendo Switch is not backward compatible with games designed for other systems
During the long interview published on the pages of TIME, the president of Nintendo has silenced the rumors about the backward compatibility of Switch, confirming that the console will not be compatible with games and accessories designed for other systems.
These are the words of Tatsumi Kimishima: “Switch is not backward compatible with games designed for other systems, and is not currently compatible with controllers designed for other systems. Support for certain controllers may be considered for a future update. In some cases, games from past systems may be re-released for the Nintendo Switch system as either enhanced or original versions.”
During the January presentation of the Switch, Nintendo revealed that Mario Kart Deluxe 8 would hit its new console on April 28. The improved port includes new characters, items and battle mode with some changes. In January 2016, it was rumored that Bandai Namco was working on a port of Super Smash Bros for the next Nintendo platform – in that time called as NX – but so far has not announced anything about it.
So there will be no backward compatibility, therefore, even if the arrival of Nintendo games is not excluded already out on other platforms, such as with Mario Kart 8 Deluxe and much rumored (but not confirmed) Super Smash Bros. and Pokemon Sun and Moon.
