Wow some awesome emulation news and on one of the present generation consoles, Retroarch the multiconsole emulator has been ported to the Xbox One, heres more info:

Retrix currently supports the NES, SNES, SEGA Master System, SEGA Game Gear, SG-1000, Megadrive, Gameboy, Gameboy Advance, and in the future many other platforms.
Here's how to take advantage of Retrix on Xbox One:

  1. Download the .APPX package for the Xbox One (29.4 MB)
  2. Once downloaded, to install Retrix on your Xbox One, you need to switch your console over to developer mode, this is the most complex step, you can either follow this guide by Team Pegasus, or spend an one-time fee of $19 to Microsoft.
  3. Enjoy! Retrix supports the local game for two players, and all credit goes to Albertofustonini to create and maintain the Retrix project.
