Broadcast info to other handhelds in Japan.
Nintendo has released a cute little gizmo for DSiWare in Japan that lets people broadcast image and audio samples to nearby DS systems via Download Play.
The idea behind Make Your Own DS Guide is more honourable than whatever dark thoughts you might be harbouring though it’s so that people can create guides for events and locations.
That’s according to Joystiq, which also reported that the guide program is a pet project of none other than Shigeru Miyamoto, who is smiling and radiant in the (as-yet untranslated) Iwata Asks column linked from the Guide app’s official website.
