Raiscan found that already? Aw, man, here I was, thinking I was on to something. :/ Still, it could prove useful. I dunno.
Anyway,
the route has been finalized (now with convenient
save state so you don't have to watch the first 12 minutes)! The second part was a bit of a headache to get done, but it's done! I'm positive there's a better route, but this is the best I could find. Man, I'm excited!
It doesn't go all the way to the end; it's pretty obvious what will happen one I escape the glitched throne room, and not much in the way of exciting stuff is going to happen, so I decided to spare you the boring details.
But yeah, it goes through and destroys the first 38 metroids and enters the last area with 45 missiles left - just enough to finish the game - in around 30 minutes. 30 unoptimized minutes! I'm guessing the run will end up being in the 25-27 minute range when finished.
Anyway, enjoy! Go ahead and ask any questions. I don't know when I'll continue with the run, but this should do in the meantime.
