Retroarch is my favorite emultor, mainly due to the sheer volume of emulators available, can't go wrong here. I just wanted to point out that I was looking for a way to play all my retro games on Xbox One. Nesbox works flawlessly with my Xbox One. Just go to windows explorer on your Xbox One, have Nesbox pinned as a favorite website, and your good to go. It works with one drive, so I had to upload all my games to one drive, but man this is now my favorite way to play. For those Xbox guys out there, this is a good way.
