Submission Text Full Submission Page
Dr. Jekyll is a simple man: he just wants to take a nice, peaceful stroll to his marriage, but the entire city is up in a civil war. Fearing for his ability to walk right, Jekyll manipulates time to conveniently have every obstacle out of the way, not fearing any consequences to the laws of physics and space-time continium in the process.

Game objectives

  • Emulator used: Bizhawk 1.11.3
  • Abuses programming errors
  • Takes damage to save time
  • Heavy luck manipulation
  • Needs to be watched at 300% speed minimum to be bearable

Improvements

This is 2173 frames faster than the previous cancelled run.

Screen 1-4

No improvements.

Screen 5

Use the stair glitch to skip the majority of hasards. This is needed to keep more METER for barrel boosting in Screen 6. I choose this screen because it leads to a rather delicate result in Screen 6 and is the most easily accesible stage to stair glitch on. This is a little bit slower than the normal way, but I can't do much about it.

Screen 6

New tech was used in Screen 6. You see, the bombs in this screen have a very, very wide explosion radius: they can only be dodged by perfect walking left and jumping. The main obstacle was the barrels. But instead of trying to manipulate good barrel RNG in order for them to not come (which wasted quite the frames in the process, because that lead to even worse barrel RNG after the bomb; I could not jump after the bomb explodes for a bit), I simply chose to befriend the barrels. My objective is that, when a bomb is placed, Jekyll gets to a safe position as fast as possible. So I manipulate barrels to be on Jekyll the instant he touches the bomber (so he places his bomb). This way, the barrel knocks me back out of safety, and I can continue peacefully manipulating RNG. I also manipulate a barrel to transform into a dog at the start of the level because why not.
After the first stair glitch, this gets a lot simpler: I simply hold Left to avoid bombs.
After entering another stair while stair glitching, I get a perfect clip and walk right to safety.

Tricks

RNG Manipulation

All of the hasards you see aren't fixed encounters (except for the pink bombers, which are fixed but avoidable; I'll get to that down below), they are random. RNG is crucial to manipulate ennemies so you can hold Right more optimally: you basically don't want anything to bother you. There are two ways to manipulate RNG:
- mini stutter stepping: when you hold Right, Jekyll doens't actually move forward; he cycles through a three frame long animation, goes forward on the fourth frame, then starts another 'going' forwards animation. However, if you stop for 1 or 2 frames after executing this animation, you will still advance, but without fully holding Right, and consecutely never stopping. This method, hovewer, cycles the RNG very inconsitently, and only works once, until the RNG has done a full cycle.
- stutter stepping: same thing as above, but stop for 3 frames (= 1 'ingame' frame).
- jumping: jumping is as fast as stutter stepping, but causes less lag when there are entities on screen, for some obscure reason.
I always try to jump as little as possible, and prioritise stutter stepping when it is faster, because it looks smoother.

Kid Bullet Dodging

Occasionally, the kids will fire a bullet. This is simply avoidable by turning left for one frame then right again: this changes your hitbox slightly, just enough to pass over the bullet.

Quick Damage Boosting

When Jekyll takes damage, he is normally sent flying a varying amount of distance back, based on what hit him: bombs can cause him to be flung several meters across, floating the entire way through. This is why I try to make a quick damage boost: as in, instantely falling as soon as I get hit, instead of floating.

Stair Glitch

When Jekyll scrolls the screen enough so that he is barely able to fit between a 'step' and the corner of the screen, lands on that spot facing left, turns right, then jumps, he will clip out the screen and reappear at the very right of the screen. The most obivious advantage is being able to bypass dog-jumping, since you scroll past them, being at the right of the screen. However, this trick is sparingly used in the run because of its tremendous setup time (300 frames) and its utility is limited where luck manipulation can do better work in a shorter time. Massively abused in the last screen.

Hitbox Clipping

When you get stuck at the very right of the screen via the stair glitch making it so Jekyll has half of his severed body on the very left of the screen and its other half on the right of the screen, simply holding Left will change Jekyll's hitbox location from the very right of the screen to the very left of the screen. Used to skip all bombs in Screen 6. Note that the bombs in Screen 6 still hit Jekyll from the back, but he only takes LIFE damage as a wierd result.

Perfect Clipping

If you do the stair glitch, then jump into another stair, you will end under the ground. Walking for a bit, then jumping again pushes you again, putting you at the very right of the screen, at the very right position for Jekyll to dodge every obstacle in the game, including bombs.

Backwards Boosting

By turning left at the exact frame you get hit, you get knocked back while facing left. This doens't have any use, but it used when it doens't waste any time for extra style.

Despawning Sprites

By having perfect timing and RNG, you can completely despawn some sprites from appearing. This is used to despawn the kid in Screen 1 and one of of the spiders in Screen 2.

Despawning Pink Bombers

Pink bombers are crucial: they deal massive damage with their bombs, as well as causing dogs and cats to wake up and civilians to panic and deal damage in very frequent waves. Most of these effects can be dodged, but there is one who's crucial to despawn: the pink bomber at the start of Screen 3. Sadly, these are dependant on an internal timer, and I have to wait 6(!) seconds at the end of Screen 2 to despawn that pink bomber.
There is another way to not make pink bombers appear: keep a singer on-screen. Singers share their properties with pink bombers, as in they occupy the same slot in memory. Effectvely, keeping a singer on-screen will allow no pink bombers to spawn. This is also why bomb snapping happens.

Bomb Snapping

In Screen 6, if you scroll a singer on screen while a bomb is on screen, the bomb will reset and snap to your position, and the pink bomber will not come back. Very useful trick.

Confused Bombers

When approaching a bomber with the stair glitch, he will often be very confused as in where to walk to, taking him extra time to leave the screen. Most useful in Screen 6 to maximise the time pink bombers are on screen; as long as one is one screen, the next cannot place its bomb.

Palette Swapping

For very obscure reasons, stair glitching in Screen 5 and entering Screen 6 at a very specific frame will give you a rather particular palette.

Health

You might notice there are two types of health: LIFE and METER. When METER is empty, you transform into Hyde, which is to be avoided at all costs. The game isn't supposed to be completed like that, obiviously; there are no heals, and you have to complete the entire game with one health bar, which is really tricky.
The health routing is perfect in the run. The previous TAS chose to take no damage on purpose: I take as much as possible on purpose for damage boosting. Health routing has also changed slightly compared to the previous submission (see 'Improvements.')

Other comments

This is a whopping 2173 frames than the previous run, and 4316 frames faster than the current published run, even accounting the large emulation differences.
I think my work is done as defining Dr. Jekyll as one of the most impressive speedgames of history. Enjoy watching.

Okay. The run has received surprisingly good votes, currently at a 71% as I make my judgement (9 yes, 5 meh, 2 no), and I'm assuming it's thanks to all the new tech on display. It's a quite solid improvement over a run that, in all honesty, didn't even feel nearly that improvable. It was actually an entertaining watch this time around, and the majority of voters did seem to agree.
However, votes alone are not enough. The posts in the thread were a little less receptive, with all of them being meh votes or "weak yes", highlighting that the run was indeed more of an entertaining watch, but not enough to escape the Vault. I'm inclined to agree. There's not much you could do to save this game, unfortunately, even if you distort the space/time continuum and enter the stereoscopic realm for the last stage.
I'm accepting this as an improvement to the published run. Congratulations xy2_. I hope you're happy with yourself and your higher movie.
Spikestuff Puns & Barbie. Samsara, remind me why I publish things you judge.

Unless the palette glitch saves time, I personally don't like it very much.

I definitly get where you come from; unfortunately, there isn't much I can do about it. It is based on entering on a specific frame, which is coincidentally the fastest way to finish in this scenario, and delaying that would waste time.

Hate to be a dissenting opinion, but it brings some much needed variety to this godforsaken game. The game actually looks like a proper TAS now. It has glitches, rng manipulation, and a ton of optimization put into it. Sucks it's still a slow stroll, but eh can't have it both ways. Quoting myself:

What I find most depressing is that there's a good end to the game with an actual boss and whatnot, leaving there also room for a 100% run.

There's probably no person in existence who has completed the game using Hyde. It would be interesting to see, even if it takes twice as long.

Be interested.
A hundred years from now, they will gaze upon my work and marvel at my skills but never know my name. And that will be good enough for me.

Wow, those glitches at the end do change this up quite a bit. I don't know if it's good enough, though, to upgrade the entertainment ranking though. It's still a rough game to sit through, only just slightly less rough. What's the deal with the glitch where you actually walk faster at some points in Stage 6, when the game is swamped with barrels?
Used to be a frequent submissions commenter. My new computer has had some issues running emulators, so I've been here more sporadically. Still haven't gotten around to actually TASing yet... I was going to improve Kid Dracula for GB. It seems I was beaten to it, though, with a recent awesome run by Hetfield90 and StarvinStruthers. (http://tasvideos.org/2928M.html.) Thanks to goofydylan8 for running Gargoyle's Quest 2 because I mentioned the game! (http://tasvideos.org/2001M.html) Thanks to feos and MESHUGGAH for taking up runs of Duck Tales 2 because of my old signature! Thanks also to Samsara for finishing a Treasure Master run. From the submission comments:
Shoutouts and thanks to mklip2001 for arguably being the nicest and most supportive person on the forums.

I wasn't the only one who encountered that odd quirk when I got bored and emulated this game one day, mklip2001. Anyway, the run. Nice to know that a few glitches make the game somewhat more bearable to watch, but seeing as they're executed in stages 5 and 6 makes me wonder if they're really worth it. Weak yes vote.

Well, that was more entertaining than the last run...though that's not saying much for this game. The last stage looks pretty unfair, but I thought you did well making it more interesting with the stair glitch and palette inversion (any difference in the repetitive visuals is welcome for this game). The glitching made that otherwise hard-to-sit-through level pretty funny to watch. Like mklip2001 said, I'm not sure it's enough to bump it up to Moons, but good job anyway. Voting Meh.

Is it or isn't it used in this run? Seems you made a small mistake when copy/pasting the notes from your previous submission.

Nice to see this piece of "video gaming history" get a more optimized TAS. The stair glitch tactic truly demonstrates the split personality of Jekyll's character. Since I'm unintentionally amused every time I see this game, and the new tactics are pretty awesome, I didn't find watching the run too arduous. It shall receive a 'meh' vote from me. But yeah...

NES TAS of 2011
I have the console speedrun record of this crap game :) That said, I think this is a good run. I don't see any obvious improvements, but I there is one glitch that I use in my runs that I'm not even sure saves time. Also, did you know you can enter the doors in the last stage to avoid he bomb explosions? One spot seems to neglect this, but maybe it is actually slower than getting hit? I could be wrong here. Specifically 14:54 of the youtube encode.
