The Xbox One getting backwards compatibility in 2015 was a big deal, but one enterprising developer has gone a few steps further back. Through the use of the UWP and an Xbox One turned into a dev kit, Windows 95 has been shown off on the console.
As pointed out by Eurogamer, what you're actually seeing is Dosbox, a DOS virtual machine app that has been loaded up as a UWP app for the Xbox One on Windows 10. It's by no means perfect, but it's cool as all hell.
What's even better is booting up some old school Duke Nukem.
Microsoft is set to allow UWP apps on the Xbox One from this summer. Whether or not we'll be grabbing a couple of floppy discs and partying like it's the mid-nineties is a different matter entirely. But cool stuff doesn't always have to make sense.
