I still recommend checking into my above post's probable improvement.
However, view
this file instead of that one. Compared to the published run, the frame additions and subtractions are rather erratic from beginning to end, so I don't know how much faster it is. But it could shave about 45 frames. It uses a skull pot instead of sword, and the boomerang instead of cane. And I didn't use wobbling, so the first screen's dash could be inefficient by comparison. (And there could be more overlooks.)
Now, time for
something that will save 1 frame ... unless a better precision is found for the published run's method. It's mainly interesting to watch because of similar applications that could show up across the game for the sword+beam combo.
Also,
here is a potentially massive and interesting real-time run project that I was inspired to start by request. Video descriptions and embeds will eventually be put on some wikia. So far, there likely isn't anything new for TAS. Although, I do wonder about TAS applications for arrows vs. boomerang in Agahnim's Tower.
Speaking of arrows, I think Tompa has 5 redundant arrows left over at the end of the game. So, from what I can tell, the arrows in the water dungeon's statue room are unnecessary at the least; maybe a different bundle has even less meaning.
Did anyone here ever let it be known that the mirror can be utilized almost immediately prior to entering the water dungeon, to make the blocks that you move disappear?
