Vita games to save either internally or to memory card

PlayStation Vita games will be capable of saving data to either a memory card or the game cartridge, but not both.

A representative of Sony Computer Entertainment confirmed to Kotaku Japan that games which feature internal memory will not provide an option to save using a memory card.

Games which require a memory card may do so for a number of reasons, such as installing Live Arena data or for future downloadable content. The decision will be left up to game developers as to whether to use internal memory or a memory card for saving data.

Of the 26 launch titles in Japan only seven are confirmed to require a memory card, including Uncharted: Golden Abyss, Disgaea 3 Return, Hot Shots Golf 6 and Ridge Racer.

Titles such as Ultimate Marvel vs Capcom 3, Army Corps of Hell, Shinobido 2, Blazblue Continuum Shift Extend and Michael Jackson will save internally on the game cartridge.

PlayStation Vita will launch in Japan on December 17, followed by a launch on February 22 in Europe and North America.
