It is the version that ships with RetroArch so it got all the features of that.

But it is based on an older version of Citra so there no hotkey support and the performance is not as good.

But it is also the only version we can ship.

The Ponzu feature can be used to load legacy versions of removed emulators without support.

We have pressed the publish button on Flathub (Discover) so it should show up within a few hours :)
