G37NEO uses dolphin for all his runs which can easily be identified due to the high resolution he uploads with. (The Wii is not able of providing such a quality)

Furthermore, he already admitted to it several times. Dolphin runs are really easy to manipulate since you can use savestates really easily, hence why none of his speedruns should count on this website.

Have a nice day.
