It was only last week that an NES emulator was seeking certification for the Xbox One. While that was never released, a different Nintendo emulator has actually managed to get on the console. Based on the PC release of Mupen64plus, Win64e10 means that Nintendo fans can enjoy N64 games on the Xbox. However, they will have to pay $9.99 for the privilege. It seems incredibly likely that Nintendo will intervene at this point.
