This 1 player run of Chip 'n Dale: Rescue Rangers 2 is a 45.35 second improvement over fisker N.'s submission through much more aggressive boss fights and general optimization.

Game objectives

  • Emulator used: fceux 2.1.6 with TAS Editor (new PPU)
  • Aims for fastest time
  • Takes damage to save time
  • Genre: Platform

Comments

When I saw fisker N.'s attempt on the submission feed the comments noted various instances where they believed there could be a few improvements so I thought I would give it a shot.
In the end I saved much more time than I initially expected. The improvements from the movie are almost equally split between pure optimizations of the routes shaving a frame to a second off the platforming sections and optimizing the bosses. The main gain on the bosses was to simply take a much more aggressive approach and picking up and throwing the items at the bosses as soon as was possible where fisker N. tended to hold back a little while.
In the end on ever section (from fade in to fade out) I either saved frames or matched the previous attempt, excluding the final boss.
The last boss caused a problem in that between the older versions of fceux and 2.1.6 lag was handled slightly different and the last boss became slower by a quarter second. The lag change was strange and unexpected because it was the only part of the run that changed between fceux versions as fisker N.'s run actually desyncs unless you switch over to the old ppu. With the lag change it resulted that there were very few moments during that boss fight where you were able to move and not introduce more lag frames slowing the movie. As a result I have decided to go with a more minimalist style on the last level to save frames and to add cohesiveness so there isn't random period of non-movement (do to lag reduction) surrounded by sporatic jumping and twisting around.

Other comments

I would like to thank fisker N. for his run as it gave me very specific goals for levels to beat and helped come up with a few time saving strategies I did not think of on my own.
I hope you enjoy.

My question wasn't so much about what was different, but more about why those things are particularly interesting. Throwing the second player, planning when to die and show up again, and beating the bosses in a fast way all seem to be things that would make the run more interesting... I am asking because of submissions such as these: http://tasvideos.org/1660S.html The general rule is that when a 2-player run is slower, there are often two versions, as the 1-player version is the fastest game completion, and the 2-player version adds interesting 2-player gameplay. In this case, the 2-player TAS is faster though... This is just a rule of thumb, and I am not saying that it applies in this case... but that's why I am asking why these different aspects are more interesting. I don't know how many of the people who voted yes took this into consideration when voting, so some opinions on this would be nice. I did see that AnS wrote in the previous 1-player submission that he was in favor of 2 published movies for this game.

That is true, after you said that I did notice that while the voting is positive there were not very many comments or opinions listed so it would be nice to see. (Yes this is a blatant content free post to bump this up in the hopes people will comment to help you in your choice)

Well, with Chip and Dale 1 it's even worse: 1p run is slower than 2p (especially since 2p run isn't improved yet) and both runs use same sequence of levels, even though in CDRR1 player could choose levels (so since 1p is inevitably slower, I'd personally prefer it to be a "100%" run). Also, unlike CDRR2, in CDRR1 bosses tactics are absolutely the same in 1p and 2p runs. And yet both runs for CDRR1 were published and got high rates, probably because it's the game everyone played in childhood, while CDRR2 was released too late.

Believe me, I do too. Picking up the bombs is most definitely slower as it causes the boss' to act differently (I did it where I picked up every bomb, still hitting on the earliest frame and it ended up being 5 seconds slower than my current version). And that final boss is the only level in the game where lag became a problem. All other levels allowed for "dancing" without hurting the time but on that one moving around caused lag about every third frame.
But did you try to redo the run for Old PPU?

I didn't because I literally had to start the run over and I wasn't ready for the commitment for the new PPU when I wasn't 100% sure that my run would not sync on a real console where his would (I know those comments say it is more accurate in certain regards but it is the PPU being used in Bizhawk and I really couldn't bring myself to do it.) If this disbars my run it would suck but I guess it happens because I am not ready to redo this run to get it to line up since a lot of work was on minute optimizations that would be terrible to work through.

Accepted this: there were no "no"- or "meh"-votes, and the first game in the series also has both a 1-player and 2-player TAS published.
