In a major policy shift, Nintendo Co. said it has partnered with mobile video game operator DeNA Co. to enter the smartphone game market.

During a joint news conference in Tokyo on Tuesday, the two firms said they will develop smartphone games using Nintendo's popular franchises, such as Super Mario Bros. and Pokemon to target the global market.

They will also create a membership-based service that will serve as a "bridge" between a variety of devices, including computers, smartphones and Nintendo's 3DS portable game console.
