Planet GameCube is reporting that Nintendo has unveiled more details of its upcoming Wi-Fi Connection service in Japan as part of its Nintendo DS Conference! 2005.
Although few new details on the service itself were revealed, of particular note was the revelation of the USB access point, which will connect to an Internet-connected PC and share the PC's connection with DS units for online play. The unit is made by Buffalo Technology.
Screenshots of the user interface appear to reveal that Wi-Fi-enabled DS games will be specifically aware of the adapter.
