I know this puzzle is hard, but why aren't there any solve videos on YouTube yet? :O

Try it yourself at mzrg.com/js/qminx-ultimate.html, if you dare...

If you're wondering, I basically use only two algs for this: R'LRL' and (R2L2'R2'L2)3. There are more advanced methods with many more algs but I find them a lot harder to recognize and get used to.
