Nintendo launched its newest handheld gaming device, the GameBoy micro, in Japan on Tuesday.

The micro is easily the smallest member of Nintendo's hit GameBoy family, as its name suggests. At 10cm long, 5cm deep and 1.7cm thick, the device is smaller than a deck of cards, yet packs a punch - Nintendo says it has about the same power of previous GameBoy models.

It includes a 2in color LCD and buttons for both game control and menu selection. A number of faceplates can also be bought to change the look of the device.

The GameBoy micro costs ¥12,000 (about £60), and its launch was timed to coincide with the 20th anniversary of Nintendo's first Mario Bros game.

Launching with the device are three software titles from Nintendo. The first two, Dr Mario and Panel De Pon!, and Super Mario Bros, each cost ¥2,000 (around £10). The third title, Mario Tennis Advance, costs ¥3,800 (£19). GameBoy Advance software can also be played in the device.

Audio and video files can also be played through an adapter.

The GameBoy micro will hit UK shelves on 4 November and cost £69.
