Whenever something cool needs to be designed for a console, it’s always up to the homebrew community to do it. Some excellent hardware hackers were able to custom design some software that enables to Nintendo DS to place VoIP calls via the internal WiFi and built-in microphone. You even get to dial on the DS’ touchpad. How sweet is that??
No idea how you load this stuff on here, though it makes me wish I still owned a DS…
