TheAlmightyLoli made a good video about it:
Although I often had the feeling it's simply the Rorschach paradox, as in the creators, due to their communist brain damage, lack the ability to predict what healthy individuals perceive as a political dig or glazing.
And no, someone who changes his political beliefs, because a game calls him centrist, is neither healthy nor a normie.
Xenia-Canary works great.
No bios, no setup, xinput out the box and is properly tuned.
It also has custom
patches which can force higher frame rates, anisotropic filtering or fixes for certain games.
ISOs are available on the usual sites and updates you can get on XboxUnity.
I have no idea about the digital only titles, were there even good ones among the arcade and kinect slop?
