Nintendo emulation

A new patent published by the USPTO yesterday details an invention by Nintendo that would allow it to emulate its mobile game consoles, including the Game Boy line of devices specifically, in other settings, including on seat-back displays in airplanes and trains, and on mobile devices including cell phones. The patent is an updated take on an older piece of IP, so it’s not an entirely new idea, but it’s still very interesting to consider that Nintendo could have renewed interest in the idea of running its own back catalogue on many different kinds of screens.

Nintendo is a bit late to the game. They could have been big in the mobile space a long time ago, emulation or not. I'm sure a polished native version of Mario on iOS would have sold quite well.
