Square Enix's Taito division has released iPhone versions of two of its most famous games, Space Invaders and Cooking Mama . The former follows the structure of its 1978 predecessor, in which gamers shoot down waves of oncoming aliens before they can reach the bottom of the screen. The iPhone version differs through the introduction of accelerometer controls, as well as some limited touch functions.

Cooking Mama has the player make a variety of recipes through a series of mini- games, such as frying, boiling and chopping. In its iPhone incarnation the game includes recipes from past titles in the series, as well as a collection of original meals. As with Space Invaders, controls have been redesigned to take advantage of motion sensing and multi-touch.

Space Invaders is available at the App Store for $5, while Cooking Mama is priced at $7.
