Updated new TAS, for the Mega Man fans.

Game Objectives

  • Completing the game with no hearts, E/W/Ex-Tanks, or any piece of armor.
  • Movie stops after skipping the final animation. Since all the previous animations are skipped, I think I might as well skip the final animation, and get to the ending credits faster.
It's a 552 frame (9.2 second) improvement over my TAS in 2022. Most of the improvements come from Final Weapon stage, using Ride Armor vs. General (found by me, saving 531 frames). Also the 8 boss refights are improved.
Note: Although the time difference may seem like 556 frames, but 4 frames are due to emulator version difference, so the actual time improvement is 552 frames.

Tricks

Faster Charge

By pressing square and triangle cleverly, 1 frame can be saved for every 2 continuous charged shots, and 2 frames can be saved for every 3 continuous charged shots.
It's used a lot in this run, but it only works when no special weapon is selected, so when you see I changed to no weapon mode, usually it's because of this.

Soul Body of Death

Mainly used for Storm Owl miniboss (Generaid Core), Storm Owl fights, and breaking boxes during the final boss fight.
Normally, Soul Body does 1 damage every 9 frames, but if you combine it with direction change, it can do 5 damage every 9 frames.

Frost Tower Double Damage on Jet Stingray

Normally Frost Tower does 4 damage on Jet Stingray. Because the frozen animation takes a long time, hardly any speedrunner or TASer actually used it.
But when Frost Tower and Jet Stingray move relatively, every 1/9 chance, double damage occurs. This saves lots of time in this run, and it would save time in 100% TAS as well.

Lighting Web Pause Cancel

Used to skip Split Mushroom miniboss (Tentoroid).
Pausing is the only known way of canceling Lightning Web without touching it, except using Nova Strike.
With this technique, you could climb high anywhere. I've tested it almost everywhere, but unfortunately, the only time save I've found is this miniboss skip, because most ceilings in this game are sealed off.

Faster Wall Climbing with Rising Fire

Surprisingly, Rising Fire can sometimes save time during regular gameplay. It's used once in Slash Beast stage 2 where there's no train, and once in Web Spider stage 1, to make X climb on the wall faster.

Ride Armor vs. General

Found by me on november, 2024. See these videos:
1st version, the earliest solution: https://youtu.be/qGWaLHHsKyc
2nd version, the crazy higher path: https://youtu.be/qRaU0C0uJyI
It saves 531 frames (8.86 s) in this TAS. It can also save time in "X, 100%" TAS, but not in "ultimate armor" TAS.
It shows a new solution getting through the first blue door. A part of the Ride Armor is in the wall when passing the first door, and X's body will be exposed in a very funny way afterward. It requires a frame precise movement getting through the second blue door, which I've demonstrated before in my 2nd TAS.

Stage Comments

Volcano (Magma Dragoon)

Stage 1 contains several improvements over sparky's TAS, including climbing the last slope without taking damage.

Snow Base (Frost Walrus)

Stage 1 miniboss (Eyezard) is very hard to deal with without using charged Rising Fire attack. Unfortunately, the miniboss can't be killed in one cycle, because it will close after being hit too many times by regular shots.
Stage 2 is 50 frames faster than sparky's TAS, due to a different strategy of using charged shots to break the ice blocks.

Marine Base (Jet Stingray)

The strategy for Jet Stingray fight is to use 2 fully charged shots at first, and then several double damage Frost Tower, and another 2 fully charged shots, and finish it with one Frost Tower.
Screen Y position affects where Jet Stingray shows up above, so screen scrolling is used to make Jet Stingray appear faster, saving time than only doing it at the top of the screen.

Military Train (Slash Beast)

There are frame rules at the end of stage 1 and the middle of stage 2 when the train stops, so I have several frames to spare for entertainment.
I love this stage because it has the most enemies, and I got many lives through luck manipulation (although still quite rare).

Memorial Hall (Colonel)

3 charged shots are used along with Frost Tower. Colonel sometimes loses invincibility during change of moves, sometimes for only 1 frame. So every opportunity needs to be used to maximize the damage of Frost Tower.

Jungle (Web Spider)

Web Spider quick kill without X's foot parts is really tough, because every Twin Slasher shot counts, with almost no room for error.
Web Spider has a maximum 64 frame window above the screen with no invincibility time, starting after hitting it when it is just about to go above the screen.
The whole setup also requires heavy RNG manipulation, because the RNG that makes the Spider drops to a certain vertical position, without web attack, and then reappears on the same required spot is quite rare.

Bio Laboratory (Split Mushroom)

In stage 1, the vertical room takes quite some effort. New strategies are used, ending up 37 frames faster than sparky's TAS, despite not having charged Rising Fire shots.
Stage 2 has a long vertical auto-scroller room, so I tried my best to entertain.
I've tested multiple strategies for Split Mushroom, and the fastest solution uses the period when Split Mushroom is in the sky and maximizes the damage of Lightning Web.

Cyber Space (Cyber Peacock)

Both stage 1 and 2 contains small improvements over sparky's 100% TAS.
Soul Body is used 3 times in Cyber Peacock fight, because although Soul Body does greater damage, using Soul Body would cause Cyber Peacock to disappear longer than usual, so charged shots are the main weapon against Cyber Peacock.
Taking damage twice is to cancel Soul Body, so 1 frame can be saved from faster charge each time.

Air Force (Storm Owl)

This is the first TAS that finishes stage 1 without using the Eagle Ride Armor. It's 69 frames faster than sparky's 100% TAS. Although I like the Eagle Ride Armor, not using it can also be an interesting strategy for TAS only.
Stage 2 has awesome usage of Soul Body against miniboss (Generaid Core) and Storm Owl. Storm Owl loses invincibility for about 64 frames after getting hit by Aiming Laser and a bullet shot afterward. But it flies away very fast, so I can't kill it in one cycle, so I took damage to cancel Soul Body, and add another Aiming Laser and a half-charged shot to finish the fight.

Space Port (Colonel)

For the second Colonel fight, I used a different strategy than the first one, because this time Colonel makes his moves faster. For the new strategy, I manipulated the time and place firing Frost Tower to make Colonel skip the blocking animation, which saves time.

Final Weapon (Double, General)

Lightning Web is cleverly used throughout stage 1 and 2. Sometimes it's faster to destroy the giant machine, and sometimes it's faster to skip it.
I'm lucky to witness a graphic glitch of the last enemy killed before meeting General.

Boss Rush

Magma Dragoon: I used Lightning Web in the Magma Dragoon fight, and it saves 20 frames because it allows time for another fully charged shot.
Storm Owl: Unfortunately it's slower than the first Storm Owl fight, because I tried lots of plans but can't get the 4 bullet shots to hit Storm Owl in place during the Soul Body shot. The setup requires very precise bullet shots, otherwise, it won't cause extra damage. Maybe it's because of asymmetric left and right physic, or some unknown reasons, so I had to use a fully charged shot to finish Storm Owl.
Split Mushroom: A fully charged shot is used first instead of Lightning Web, because unlike the first Split Mushroom fight, this time it's higher above the ground, costing more time if hit with Lightning Web.
Jet Stingray: One extra double damage Frost Tower is used instead of more fully charged shots, because this time the ceiling is wide open, so X can hit Jet Stingray much faster than before, with no need for screen scrolling.
Cyber Peacock: 2 frames slower before, because X couldn't afford to get hurt anymore to save time after the Soul Body shots.

Sigma

Gunner Sigma: Soul Body is lined up perfectly after getting hurt, without any delay or time loss.
Earth Sigma: It has 2 attacking modes. Spike Attack mode is slightly faster, but without charged shots or Nova Strike, to end the fight in only 2 attack cycles, I manipulated luck to get Spike Attack first, and then Slime Body attack. During the Slime Body attack, I broke the blue "mini body" because it allows X to move more to the right after the fight ends.

About RNG Manipulation and Lag Reduction

This run has a great amount of RNG manipulation, often to reduce the lag during the "READY" animation. But I'm not for extreme lag reduction.
Some super rare RNG values can save about 8 frames per stage, they are almost impossible to calculate (some require planning way ahead), and very painful to manipulate; even if they are achievable, entertainment and other things need to be sacrificed.
In my view, I don't find lag reduction more important than entertainment, so for this movie, I think a decent amount of lag reduction is enough.

Suggested screenshot (frame #109256)

Special thanks to Bernka and sparky. From watching their TAS, I've learned a lot.
Special thanks to SCWeeb, currently the Mega Man X4 speedrun world record holder for many categories. His low% speedrun inspired and motivated me a lot.

nymx: Claiming for judging.
nymx: Replacing the movie file with a correction by HappyLee.
nymx: Tested the movie out and it syncs. As for the run, excellent frame war tactics. Run looks good. Very good work HappyLee.
Changed the goal name so that it will match with the movie that this TAS is obsoleting.

EZGames69: Processing...
feos: Fixed the class. It's a non-standard goal and the previous one is Alt.
feos: Woops, forgot this is low%. Moving back :D

The Rerecord Count is wrong because I updated this TAS with a new emulator version. The real Rerecord Count should be 157614. Can the mods help me replace the movie file with this: https://tasvideos.org/UserFiles/Info/638950170764812657

For reference, the TAS appears to be the same up until around frame 107000 (a few seconds before the Ride Armor in Final Weapon). This TAS uses the Ride Armor glitch to save 531 frames, and the rest of the time is saved by reversing the order of boss refights. The final Sigma battles are virtually the same. A comparison video is not necessary.

Already watched the old run and this one, adding more spice at the end for a sub 40 is what I was looking for! Yes vote!
I still learn more about English. https://www.youtube.com/user/McBobX100

I made a video with a SNES-style boss HP display (also invincibility frame display as well): Link to video (just wanted to do something different since there is no real point to a comparison video)
