Microsoft has revised Windows Store policy to remove emulators. The new rules bar any applications that emulate preexisting game systems, resulting in the removal of a popular program that supported games from Nintendo and Sega consoles.
The new policies explicitly disallow emulators on “any device family.” It’s a wide reaching change that stymies emulation efforts on Windows 10, Xbox One, and mobile devices. The policy was amended on March 29th and is just now affecting applications in the store. One of the emulators getting the axe is the NESbox Universal Emulator. It supported ROMs from the NES and Super Nintendo as well as the Sega Genesis.
