Always great to see homebrew running on the latest consoles, Dosbox is a Dos Emulator, heres more details:

Recently, the Xbox One was updated with a feature that allows anyone to 'Develop' apps/games for it, using the UWP interface, and even tho its very limited in the sandbox, someone been able to figure out a way to get 'DosBox' running on it, allowing them to get their Xbox One to boot-up Windows '95 and play the first version of Duke Nuk'em the video game, all tho the framerate a bit slow for now!
Developer vcfan has not released any binary at this point. Nevertheless, this looks pretty cool, despite the awful framerate. The Author says this can be improved though. Vcfan says: "Its slow for now because it's only using the cpu interpreter. The dynarec still needs work since it produces crashes on 64bit, but it flies with it."
In the video, we can see the developer running Windows 95, Duke Nukem 3D, and a tiny bit of an SNES emulator (but no SNES games).
That's pretty cool, and it would be interesting to see where this goes. This could quickly make the Xbox One a more interesting platform for enthusiast devs than the PS4.
In some of the youtube comments, vcfan has promised he will publish the sources in the days to come, so stay tuned.
So this is one story we going to follow for sure, as it seems the UWP mode on the Xbox One, might just open up some neat doors!
