I've downloaded v1 nightly for the raspi, extracted the archive directory contents onto an empty fat formatted sd-card, plugged the sd-card into my raspi 3b+, got some current into the raspi and....
.... staring at me is a beautiful screen with a picture of vertical bars displaying from black (left) to blue (right) ....
And that seems to be it. Nothing more, nothing less

Is that the current state of the native Raspi version ? e.g. more development is required to make it do more than that picture ? Or am I perhaps doing something wrong and/or is there additional configuration required to show some lovely cat eyes (whether they be looking for a boot device or those accompanying the about window) ?
