Japanese gaming firm Nintendo is linking up with a mobile firm company firm to develop games for mobile devices.

The announcement from Nintendo Co comes after years of scoffing at the threat from smartphones.

The tie with DeNa Co means that Nintendo's trademark game characters such as Super Mario and Pokemon could finally feature on smartphones and tablets.

Such characters have been fiercely protected by Nintendo, appearing only on Nintendo platforms such as the Wii home console and 3DS mobile machines.

Both sides said they will build a membership service for global consumers for various devices.

They said the mobile games will not be mere adaptations of the games already out for the Nintendo machines but developed especially for the smartphone experience.
