Can't watch the video now, but how straightforward is this to get running well and actually use? I tried Dolphin through Retroarch on SX, and it was a pain in the ass to get going for a number of reasons, none of the tutorials accurately described like, anything, the community on the site I was using basically had a "don't ask for help because if you can't figure it out you're an idiot and we'll ban you" rule, and went it was all said and done I couldn't get the ONE game I wanted to play (Metroid Prime) to run in any way I could describe as "not absolutely fucking awful" and "totally not objectively worse to just plugging my GameCube into my 4KTV and playing in 480i".
