Two Nintendo devices have recently been approved by the Korean Radio Research Administration.
The first was certified on April 18, and is described as a small video player. No details were announced of this new device other than its new model number, WIS-009.
The second, registered April 21, is more familiar. It's model FTR-001, which the RRA listing classifies as a specific low power wireless device. This is none other than the Nintendo 2DS, which already launched in Korea back in December.
