User Files for Chip 'n Dale: Rescue Rangers

This trick was discovered by junkyard_dave. The movie is a regular walkthrough with the TAS part in Zone F to show the trick.

Bizhawk 2.3.1, but it successfully syncs on Bizhawk 2.9.1. A USA ROM is required of either good and questionable dump quality.

This RAM watch contains helpful addresses of Chip 'n Dale: Rescue Rangers for NES.

It includes X and Y positions, and X and Y subpixels for both players.

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.

Emulator: BizHawk 2.9.1

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

This is a copy of https://tasvideos.org/1128M which plays back on BizHawk 2.9.1 (NESHawk core).
It's slower than its FCE Ultra counterpart movie by 29 frames, which are extra lagged frames detected by NESHawk.

The input file survived two conversions (FCM -> FM2 -> BK2), but it maintains its original ROM hash and other metadata, except rerecords count.

Bizhawk shows a hash mismatch warning, but it syncs on ROM with the hash I provided above.

I resynced it mainly to have a convenient way to copy-paste Bonus stages and boss fights between two TAStudio windows.
It also might be useful for console verification, to check if NESHawk polls the input correctly.
