This is some weird bug introduced with Atmosphere 0.9.2, Scires will hopefully fix it soon.

Happens in various situations, not necessarily an error, but still prevents booting. If you got this because you downgraded, it's because you downgraded between major/key versions (7.0.x -> 6.2.0, 6.2.0 -> 6.1.0 etc) without console initialization (deleting system save files). To recover from that: Delete system all save files except 80...120. Keep in mind that this will effectively be a factory reset.
Thanks, it always reminds me why I love this scene so much. We take our time creating something that was never done before, adding support for patched units and by that invest our unpayed freetime and hearts into a project. But hey, 8.1 support was a little bit too late because Hekate added a freaking GUI and Emunand support, better complain to the developer.
