It was a commit (I later reverted) that would have added support for SX OS - I'd guess that dropping the normal hekate sdfiles would also work (though it would create some files that will not be used but whatever lol)
Ok just trying to grasp things here. So you don't know if using the hbmenu.nro from within your sd card zip will work at this point because you haven't tested it. Curious though, why drop the support and revert back? Many people would prolly like using sx os payload for xci and homebrew. And if your hbmenu is updated to function better than the 2.0.0, then I would want to use it. PS, Excuse my ignorance if I am not understanding any of this correctly. It's a little foreign to me.
