Several days ago, we reported that an NES emulator had been submitted to Microsoft to appear on Xbox One. While it seemed unlikely, the company has since approved the request. The makers of the emulator posted on their Twitter that their application had passed Microsoft’s certification process. It seems highly likely that Nintendo will step in at this point to prevent the emulator becoming available. As the drama unfolds, we’ll keep you updated.
