To put in my own two cents on the matter. As far as I know, I've never seen someone play without a Mii on a console, except on Dolphin. That pretty much is the biggest proof. Also, about the graphic differences between console and dolphin, the conveyer beld arrow texture is a lot more transparent on Dolphin compared to console. That has been known for years now. The gifs on rcs his post show it clearly.
About the graphic difference on CM about the escalator on Tyler his post, I'm not going to say anything about that one since that's the first time I heard about that. :p
Seeing how quite a few well known top players from the community that play for years now are saying these things, this run definitely needs a re-review by the admins. Though, personally, I think the no Mii thing is the biggest proof of emulation usage. (Unless ofcourse I'm missing some secret way to get rid of your Mii and even the guest Mii. If that exists, please show me! :) )
