I can't really take a screenshot that would prove it, but, I successfully completed the Majora's Mask Three-Day Challenge. In which you have to beat the game without ever playing the Song of Time after the first time. You can technically save and reload if you save at an owl statue and copy the file.
Other than having to complete the dungeons very fast, you can't get Epona any later than 6PM on the first day. So in those first twelve game hours you have to get into Woodfall Temple, get the bow, warp out, get into Snowhead Temple, get fire arrows, warp out, melt the ice blocking Medigoron's powder keg shop, blow open the way to the Goron racetrack, run back to him and get a powder keg you can take to open Romani Ranch. Which is a hell of a lot to do and requires near-perfection. The rest isn't quite as demanding. I ended up with a bit of time left over after saving Odolwa for last and used it to get more heart pieces. I had ten containers at the end. I didn't get the Bunny Hood, I mostly spun around as a Deku or rolled around as a Goron to go fast (which, to do this, you gotta). The only non-critical mask I picked up was the Stone Mask, which may as well be a critical one. I've never gone into the Pirate's Fortress without it, and quite a few rooms in Great Bay Temple and Stone Tower Temple have obnoxious respawning enemies who make life hell if you don't have it.
Biggest mistake: I forgot to go get the Song of Storms on the first night, even though I remembered to go get the Captain's Hat for that purpose. The Stalchildren are circling different graves on the second and third nights. But thankfully, it is actually possible to get into Sharp's grave on the second night without any glitches, seen
here.
