And rather sloppy, as well... gameplay-wise, framerate-wise, and even sequence-break-wise... IMHO the early super missiles is a bigger break than early power bombs...
If you need some help, check my youtube profile for my suitless run. I've used Saturn's route but I'm going to redo the run with a slightly different path later on.
No, JXQ tested that and it would be slower (and with the new suitless norfair route for a 100% it is to even less help), for a 100% unassisted though it might be faster, blueglass is planning to take it IIRC.
But at any rate by not being to any great help I meant that it does not help you to do any other skip or save a lot of time, early supers skips one boss and probably saves something like a minute.
