A Nintendo 64 emulator named Win64e10 is now available for download on Xbox One consoles via the Xbox store.
Shown off in images below by Reddit user CWade3051, the emulator is a product of Microsoft's allowance of Windows UWP apps on the machine. Another app serving a similar function, named the Nesbox, was quickly removed a while back by the gatekeeper.
Features include the ability to play all Nintendo 64 games, One Drive ROM/savestates import/export functionality, game save/load, save slots selection, MOGA and Xbox 360/One controller support, virtual controller/keyboard/joystick compatibility, turbo mode, cheat mode, continuum mode, and video/Input configuration.
Though the emulator's Xbox One functionality has been available for two days now, there's no guarantee how much longer it'll last in the marketplace. If it's indeed allowed, then Nesbox may make a return as well.
The app is also available for purchase on Microsoft's online store for $9.99. Be warned, however, that it has already been met with mixed reviews on other devices.
