Auris Amazing Arch Adventure (Savestateless)

Pretty neat little short romhack, but Star 15 took me 2 hours to figure out. Ended up working out a strategy where once up the first platform, made it so half of mario was visible behind the wall from the east, then wk the last top brick on the left. Then the hardest part: mashing A until i have the appropriate angle (mario's hand reaching over the wall from a southwest cam angle), then pray you loop around and hit the super thin wall and not its edges which lack any collision whatsoever. Then you're homefree so long as you don't mess up the last arch like I did three times :]
