Currently supports NES, SNES, GB, GBA, SG-1000, Master System, Game Gear, Genesis, Mega CD. I started making this because I wanted something more mouse/keyboard friendly than RetroArch and because I like my Windows Phone and wanted more games for it. The app's UI is designed to work on Xbox One too. I'm wondering how much interest there is for something like this: to release RetriX properly (getting an Xbox to develop on, package it for sideloading etc.) I'd need to raise some money. Project is hosted on GitHub. Follow me on twitter at @aftnet for updates.
