A patent has popped up that Nintendo filed back in November 2001. It is for a "mobile phone type electronic apparatus" that contains a CPU for a phone and a CPU for game related process. In a sentence: It's a cell phone that pauses gameplay when there's an incoming call. That button placement, though, looks extremely uncomfortable! But Yoshi to that patent drawing? Cute.
