This TAS competes nearly half of the game and stops at vertical section of Zone F where a box ascension glitch must be performed to save time. In order to perform it, you need to make Y subpixel of both players identical at the moment when you enter the hole. Subpixels is semi-random values which affect the dynamics of players' dynamic of movement. When the player stays on the same height, its Y subpixel loops (that's why it's not completely random).
The problem is, I spend 40 frames on matching Y subpixels. There must be a way to save a little more time.

Here is a RAM watch file: https://tasvideos.org/UserFiles/Info/638549448117300121
The addresses you need to follow are 0460 and 0461, which show the current Y subpixel positions for Chip and Dale respectively.

Please, help me optimize it, or else I will go on with the existing optimization. I will include you as a co-author, if you want! I didn't manage to improve it, so now I just go on.

Although, it isn't necessary for ROM dump to be good. If the movie syncs until the end, then it's accepted.
