Nintendo Allows Japanese DS Gamers Taste of Wireless
Gamespot has the word that Nintendo will be allowing Japanese gamers a full taste of the DS' wireless capabilities. DS owners will be able to download content at kiosks in selected stores across Japan. From the article: "[Downlaoded] demos will remain on the DS units 'until power is turned off.' The one exception is some additional music for Jam with the Band. 'After turning off power, the [Jam with the Band] data remains,'"
Yep, I've had my DS on standby for a week before and it was fine.
Just close the lid and when you open it you're exactly where you left off.. really slick.
