There's absolutely no way you're going to play such a demanding game on hardware so outdated and underpowered, to the point of this almost being hilarious. I'm afraid that due to the fact that emulation has a lot of overhead compared to playing the game on an actual console, demanding games such as Super Mario Galaxy are pretty much the most demanding real-time application you can run on two cores of a CPU, and hence you need a reasonably highly clocked Haswell (ix 4xxx) processor for that game.
Also, never trust YouTube videos, as they're usually on older revisions which are less accurate, and cause games to break (but run faster) or use the wrong settings, which causes games to break (but run faster), or are just flat out lies so YouTubers can brag about how powerful their system is.
