Challenger: I might tackle 2p warps, but it's definitely not on my "next projects" list. The 1p warpless is very long / 2p warpless is already updated and no real incentive in working on it.
2p warps probably needs discussion with feos about "movie goals" as we used previously the fastest warp 1 level, but I think that after the reactions from HRDQ showing the TAS, we could definitely spice up it to include some entertainment/speed tradeoffs.
Captain Forehead: by pausing and unpausing the game alternating between the two player's pads without losing time. The previous-previous submission notes includes it. This was abused in most of my game end glitch runs but this one only at level 1. On level 3 it flickers the background too which could be seen as a negative thing (and probably went unnoticed as lack of feedback).
Alyosha: wanted to emphasize the trick and the ending result really differentiates enough from previous versions of this TAS
FCEUX 2.2.3 version (the original version. this submission has different inputs for resyncing random factors and payload on P2 pad):
