All information is obtained via reverse engineering of legally purchased devices and games and information made public on the internet (you’d be surprised what’s indexed on Google). The goal of this project is to experiment, research, and educate on the topic of emulation of modern devices and operating systems. It is not for enabling illegal activity. Though it is still under development, it is able to run certain games smoothly. It was successful at booting and running Forza Motor Sport 4 soon after its release. Typically, the emulator updates once every two to four weeks, with Patreon supporters receiving updates a week before the public release. It can run most games of XBox 360 on PC devices (see also Android OS and iOS version).
Xenia emulator is an experimental project compatible with Mac OS.
