As for the way up the mountain, that is easy as hell... just walk up the seam (it is a very easy one). Then just backflip (or sidehop since it's faster, if you can still land on the seam w/out falling off, though a backflip would make backrunning on the seam a possibility. Get all the way down to the end, and then do the rest...

vid of the 1st part...
Oh, so you know, mupen is highly homosexual and you are gonna have a harder time than usual getting the bomb boosted hover. MAKE SURE you have a great angle and you don't have to TURN sharply (aka get everything out of your momentum) because Mupen is retarded and if you are out over the void part you can freeze it w/ a bombchu shield drop just like in forest... It still is possible I'm sure, its just you can't aim for the farthest left corner, but slightly to the right instead... it is a fraction higher so it may be alot harder unless you get great distance already.
Huh.. that is a load of bs... in mupen... you can hover over void and shield drop a bombchu... just not while backflipping... lol.
