There seems to be hope 
just wanted to start converting it to cul/cun like many did I stumbled across this:
Really looking forward to the release now. I love it when I can keep the official firmware
Was this included in the official package? My cube just lost settings (again after 1,5y), and I’m thinking of a way how to solve it permanently…
it was merged according to github and I didn’t have a problem since then
