No left+right TAS TWR commentary.

Ever since I started to make TASes and other speedruns for Super Mario Bros, this is first time, when God led me to so deep game learning and using RAM watch for manipualte subspeed. I didn't even knew that it exists before.
Difference between TAS with and without left right is that left right gives instantaneous acceleration and deceleration to walk speed. Without left right it is also possible to accelerate and decelerate faster, but in some cases it not works as perfect.
For fastest no L+R acceleration, do a backward jump with delaying 1 frame between pressing L and R+jump. I don't know why it is faster, you don't have to delay 1 frame, if use L+R, but without L+R it faster.
For decelerating, do a jump, stop press B, while still holding R. It will decelerate speed to walk. When Mario landed, press L. It would give you a perfect stop. This exact setup used in 4-2 warp zone turnaround.
Becuase of framerule system, no L+R TAS WR don't losing any time comparing to L+R until 8-4! However it is lot more tricky to save some of this framerules and not so much room for entertainment. So this TAS WR is much harder then normal TAS WR and this time I wasn't copying any inputs of actual timesaves, except only 4-2 inside framerule routes, but I optimized them even more by myself. Well, actually after first look for this TAS, I was 3 frames slower in 8-4 and thought that I can't found better combination, so I copied inputs for this 3 frames. Then after redoing TAS again for more optimization and entertainment, I decided to challenge myself more and reseted this inputs and did them myself. Of course, I had a look at them before redoing, but I didn't memorized them and tried different. Thanks God, I got a better understanding of what is going on there myself. Great God.
I also tried to be a lot more entertaining then Maru, because his TAS was concentrated on speed. For example, 1-1 and 4-1 have REALLY UNUSUAL FLAGPOLE GLITCHES, I didn't saw it before.
Also flagpole glitches are optimized for perfect acceleration to the castle, but it not meaning a lot. Maybe a frame or 2 from slowest way.
I could do 1-2 1 frame faster then Maru's TAS (Maru also could, but he wasn't bothering, because of framerules). You can see it here https://www.youtube.com/watch?v=HFRTO8qKrj0
In this TAS, I did a lot of entertainment slowdown, which somehow messed up something and I got even little bit slower warp zone. Still enough to save framerule and faster then RTA way.
And then, of course, I used a fastest way of doing 4-2. Maru also knew it, but forgot, when made the TAS)). I also did barely better optimzied warp zone for subpixel.
In 8-2, I did different entertainment, while waiting for bullet bill.
1st koopa's shell kick is much slower then 2nd, so it is not possible to kick both and still save framerule. Maru kicked 2nd, I kicked first.
8-4 is most important part, when it is not possible to match TAS with L+R. The fastest way in 1st room is MUCH LESS OBVIOUS then it looks. It is 1 frame faster then perfect RTA setup and not works with normal fast accel. This is one of frames, that I lost in first try of doing this TAS. Intresting that L+R TAS, which is 1 frame faster in this room also have very unobvius combination to get perfect fast acceleration there and save perfect frame. It was one of last founded timesaves to SMB TAS, done in 2009.
Walljump room is again much more obvious than it looks. L+R at the pipe for accelerate not changing it a lot.
Now coming to turnaround room. What to say there? It looks confusing again. First time I lost 2 frames here, tried everything and couldn't beat it. I copied Maru's inputs. After re-doing TAS and saving frame at first room of 8-4, I decided to re try it. I analyzed subpixel values, and tried again and again and again... and then I saved just few subpixels, being still 2 frame behind. Then few more. And again few more, just enough to pick up another frame. I was very very happy and surprised a little bit. Then I tried little more and saved few subpixels. And few more. And few more, but still not enough to pick up final frame. Then I started to analyze subspeed values from "0705" unsigned adress from RAM watch. I still don't have same talent for anylizng this stuff as Maru or HappyLee. But I retested everything again and it worked! I was shocked. God is amazingly good, but I didn't expect that He will give me so great sucsess here, even when I knew that it is possible. After saving frame, I looked into Maru's TAS and it had same subspeed value, but with little bit different jump/R combination to manipulate it!
To be more different, I put a double fast accelertaion into pipe there. It is not any better, because you need slow down to not bump into pipe after backward jump, because backward jump happens 1 frame later for fastest speed and it is nomrally faster by better acceleration. At this TAS, it is still enough to save perfect frame with backward jump, only few subpixels more to the right. I could get a perfect subpixel too, of course.
Water room don't have any way of acceleratte faster or swim backwards. But you can see that I actually did backward exit! It was small slowing down for entertainment, which still gets same frame.
Nothing special in final room again. Luckily, it is possible to get good pattern in both L+R and No L+R perfect TASes without waiting at the title screen.
Overall, the all glory comes to God, because I couldn't get anything of this without His help. Very happy to work with Him!
