Yes, as I work for MS I can let you know that it is possible. There are no restrictions from MS side that would not allow the app to be published on the X1(Store). And the only reason for it to be removed would be complains from consumers or corporations(Nintendo or others) because of copyright protection.
| Seece said: With the news that Windows 8 apps will become universal, it's entirely possible we see the GBA/SNES emulators (already on the MS windows store) available on Xbox One!! |
But is this news?
