=== END OF STAGE 2 (Frames: 5092) === (pr:5100)

Implemented Exonym's idea, and ended up with this mess. Apparently slower in the immediate segment, oh but we make it all back up in the next. Yet we lose a frame and break even on the next transition, but don't worry, the better camera makes it all better before the door, and you saved a frame rule.

I mean, sure. I did end up with something faster overall. I'm just really confused how it works out.

More specifically, I did a turnaround landing before Flame Charge. I did not Flame Charge out of the air and onto the slope. Thing is, if you're not on the ground when doing the Flame Charge, the next time you come into contact with a floor tile, you will stick there and be forced to wait it out until the Flame Charge ends. The slope tiles don't block you, and the "magnet" tiles found around slopes stick you to the slope, so we're good there, except again, once the slope ends and we move on to floor tiles, we get stopped. Walk a few frames so that we don't end our dash before that Flame Charge out.

Oh, and this file has my hastily attempted parts of the end stages tacked on. Yes, I'm having trouble manipulating ammo drops properly. I'm a bit too slow on s12, the Stage 4 look-alike.

Well, I fixed up the traversal of the flame tunnel after miniboss. 2 frames there.

Applied Shot Counter glitch again. +2 lag, -4 frames taken to climb past an enemy we once had to delay for. Might be possible there's a better enemy to shoot the laser on for lag purposes.

Optimizations in the final rightward segment, and threw away a frame intentionally to sync boss. I feel we have 4 frames delay on dialog frame rule.

Compared against previous bests. Did what I could to resync. Currently delaying 24 frames at stage select.

Don't like transition of Segments 4 to 5, particularly as we delay for an enemy we have to destroy. That is my suggested next target for improvements.

Basically, the Shot Counter glitch allowed us to switch weapons while the charged spikeball was going. It is triggered by firing an uncharged laser and having it hit an enemy many times, generally by using the screen edge for rapid respawns. Not my doing, ThunderAxe31 was doing some intricate analysis and determined Team 2 had the right idea somewhere.

=== END OF STAGE 5 (Frames: 5067) ===

I kept getting reminded of that ledge landing in Segment 6. Well, okay, it was only three times, but it clearly wasn't stylish. My only solution to it was to select a different height to solve it, ultimately by climbing down the ladder for 9 additional frames.

Let's talk about the falling cycle. Address 1E6C. At terminal velocity, this cycles through 34 going up to 42, then snaps back down to 34. It is 9 frames long. When it reads 42, the next frame will be zero-speed (or, if camera is scrolling, then the frame after that). So we have 8 frames of 4-speed and 1 frame of 0-speed. The terrain is positioned in such a way around that ledge that I get three or four frames of this 0-speed. It is also positioned so perfectly that I need four of these 0-speed frames in order to get the time I need to fall past the ledge. Because of how the fall cycle works, it only matters where I begin falling, as opposed to when, so the only real hope here is to adjust the height where I began falling in the first place. Ladders are slow, I had to climb down 9 pixels, 1 at a time per frame.

We're sitting on 4 frames before the door, a frame on the ladder leading up to the door, and one more before the Flame Charge underneath that wall on the way to the up segment. We're 3 frames away from a frame rule. Oh, and I basically ran out of useful ammo at the boss, but at least it was just enough.

The reason why the delay before that Flame Charge I mentioned, is because I fall through the floor I wall jump up to without the delay. Apparently this is due to some frame rule.

Oh, and I did change up the 1st boss re-fight to something less satisfying. My weapon choices pretty much force me to take damage either because I can't reach the boss on the first vulnerable frame, or because it would trigger lag frames otherwise. But at least I consume ammo I won't be needing too much of.

BK2 begins from savestate

Huh, so now we have five boss skips. I don't think ammo management is a problem anymore. Knew that one enemy looked fishy.

Basically, there's this fish enemy we can spawn. Exonym's previous attempts didn't get this one to move, but I then found we can face left and jump early enough. Our important pixel gets us past the floor tiles, and down low and early enough. Once it's out of the de-spawn zone, it's a matter of delaying it long enough to meet the boss, then kill it. That enemy moves rather quick and will de-spawn off the right side of the screen without the ouch delays.

If anyone's curious, the base movie the savestate came off of was Team 4's run.

Stage 4, end of Segment 6. Some time before that last ladder of the stage.

Didn't like making that jump at all. Not after the Flame Charge, and not before it either. Let's get rid of it entirely!

This did mean I needed to adjust my dash, throwing away two pixels so that I remain on the platform for one more pixel. This was exactly enough for a turnaround landing after Flame Charge.

From there, I spent some saved frames by avoiding save platform lag, as otherwise the frame rule would eat my savings,

=== END OF STAGE 2 (Frames: 5100) ===

Looking over the starter input for Segment 0, there is a fix we need to do. I would leave it an exercise to experienced Zook TASers, or anyone who has read my latest post (well, it was the latest until I make one linking to this file), but basically, first dash tap before jump is the clear frame improvement. Fix that, later.

We miss the frame rule by one frame. Snap. At least I got rid of an Ammo Tank refill. Frames were lost on item manipulation, so this stage is extremely sensitive to the 32-frame cycle. Met the boss of s2 on two barrier HP left, which is a problem because I need to take damage to reduce lag, so lose the HP against two of the shots.

Oh, and implemented Boss Skip for the second boss re-fight. SegmentCounter script claims 180 frames on that fight now.

All frames from earlier stages have been carried forward to the end. We've lined up on the 32-frame cycle after Stage 3, so sync happened without issue on Stages 6 and 2.

The basic strategy was to use the billions of frames we've saved, and incrementally lose them on the way to the end until we're left with only a few. Somehow, the stage had a lot of added lag, apparently 4 extra lag, so we'll need to reduce that. I have thrown away three frames, two of them at the end of the stage, so now might be the time to find ways of strategically delaying to get around the lag. However the delays work, as long as we don't leave our current frame rule, this will not affect sync of the remainder of the run.

I've carried all the saved frames we had into Stage 3 now. This would be the 8 frames from before s5, but I had to find more hidden about in various spots, and ultimately ended with another frame rule pulled right out from s5.

I went ahead and changed a dash right at the breakable blocks. Keep in mind, when jumping out of a dash to a short ledge, it is faster to do the first tap as you make the jump, and finish the second tap when you land, as this way, you have one of the zero speed frames from tapping overlap with the zero speed of ending a dash with a jump. Actually, a lot of savings in Stage 5 was thanks to implementing this trick.

I made a few attempts at the lazy-sync for the segments after the miniboss. Well, we did save a touch over 32 frames, did we not? The game wishes not to sync on this matter.

17 frames saved in stage 3, segment 2. the movie desyncs after the miniboss due to animation frame rule. Also note that the rest of the movie remained unchanged.

In order to achieve this, I simply used the bubble barrier again, just before segment 1 ends. This saved 10 frames.

Also, I discovered a new glitch. At 44842, you may notice that Zook does dash on ground right after the Flame Dash is ended, without having to mash the R button, but just keeping it. The game is actually continuing the ground dash started before the Flame Dash. Thanks to a different Y value, Zook managed to stay on ground after the flame dash ended, so he didn't need to jump and the ground dash didn't get broken. This saved 6 more frames.

Lastly, 1 frame was saved, probably for the different Y value, near the save platform.

Well, I saved frames in Stage 7, carried that through Stage 1, and here we are in Stage 4 trying to squeeze out more savings. I removed a pause thanks to better item drops. This dropped a frame rule. I had 2 frame rules before this stage and 2 frame rules after. Now that I carried the 2 frames rules forward, that would be 4 frame rules, which I can trivially remove for the 32-frame item cycle, but since I saved an extra frame rule, I'm now stuck with 8 frames delay in stage select after Stage 4. I guess I'm not getting a free ride in manipulation if I want to get rid of that delay. I saved too many frames for my own good!

In other news, I copied Team 3 straight to the first boss we can skip. Having not put in much time on trying the skip (I took more time typing this paragraph than trying the skip), I have not succeeded. As Exonym is the one who confirmed the skip, that's the one to ask to make it happen again, as first-hand experience should make it a lot easier.

=== END OF STAGE 1 (Frames: 5576) ===

Turns out, this stage was on the good side of the frame rule before the 12 frames, so then it went onto the bad side. I poked about for stray frames and got on the good side again. I also exited the boss a frame earlier, but this will be lost due to animation frame rule on the next stage. 17 frames delay right now, hopefully Stage 4 will prove receptive to 16 of these (and again, that last 1 is lost to frame rule).

2 frames on Segment 0 was saved. One of them, apparently, was because I started a dash a frame late, so I enjoyed an extra frame of 0 speed at the tail end of the previous dash. Fixed. Also, some complicated jump mechanics got me another 2 pixels, which ended up worth a frame.

After that, I somehow ended up at a different height on the transition to the final horizontal segment. A few adjustments were made to deal with the change, and apparently it's faster.

Stage 4... After I get rid of the intentional delay, I'll have items to manipulate all over again. This was a tricky stage to get right. We'll see if I can lose zero frames on item drops.

Also, copied in Team 3's input to the start of the end stages.

Exhibit 1: Stage 7
Remember those ceiling clips I said I was frustrated about? I took a crash course in "bashing your head through problems" and learned that the magic position is being in Screen Y Position 40. Or 41, if you're stuck in odd numbers. This is the magic spot that lets the next wall jump clip through three solid tiles, provided you are high enough. At 39 or less, you're too close to the top of the camera, and the clip will fail.

Apparently, the demonstration is on an animation frame rule, so although the SegmentCounter script claims I saved only 9 frames, the animation frame rule got me to enter stage select 12 frames earlier. Stage 1 is on the bad side of the dialog frame rule, so it is projected to turn into 16 frames after redoing Stage 1.

Exhibit 2: Stage 4
Messed around with the ending a touch, trying to beat the frame rule. I think I'm just one frame away, again! I took a different route, landing on the save platform, and it is enough to save that frame rule, but at a cost of 3 lag frames from the save. That's a steep price and I'd like to save another normal frame somewhere, but a frame rule is still an improvement. I have no idea about the transition on the way to the stage select, but I've seen it adjust by 1 a few times now, and it used to be better before this improvement. Overall, one frame rule at +4 lag.

The transition from Stages 4 to 5 is delayed 16 frames. If I combine the earlier frame savings and redo Stages 1 and 4 without loss, I will end up with 32 frames delay here. With item drops on a 32 frame cycle, this means I can remove that delay and keep full sync of later stages. Yes, this will save effort in item manipulation, but only if it works out.

Exhibit 3: Stage 2
The right side climb is showing very good promise. At the moment, it's just about tied with climbing the left side, but if we can find time to get another bubble barrier up, then the right side climb will easily win the duel. Thanks, Team 5! Knowing it is possible will let us save a few more frames off this run!

Stage 4, for some reason, had a damage near the end before using the 2nd to last Flame Charge. This damage is removed, 14 frames, but it's not enough for two frame rules. 8 frames intentionally inserted in stage select for lazy-sync.

In Stage 2, with little concern for optimization, I shot a block with a full-charge basic shot. Since we need 140 frames of charging to even hit this block, there's no way to deal with these enemies other than to have a Charge Swap Bubble Barrier already in play. Apparently, hitting the block like this means we can't switch weapons until we shoot once more first, but at least an uncharged shot counts. Two frame rules here, but again, no concern for careful optimization.

=== END OF STAGE 2 (Frames: 5150) === (T3:5412)

Threw some segments together. I'm not satisfied, so expect a few more frames out of this stage before I move on to the final stage.

For the first half, I took Team 3 and only found a few frames to save before the miniboss. I'm not entirely certain about the route between frames 57850 and 58350, which is more Team 4's route. Miniboss Skip, and up the wall with bubble barrier.

I took Team 4 for the rest of the stage, with a few differences. I still consume an Ammo Tank, but with 2 barrier HP, a change in route was done. I feel as though the stage can benefit more from abusing bubble more than I already have. I have not yet even looked at Team 5's rise through the last up segment.

Blindly copied in Team 3's boss strat, adjusting enough for position. Changed the finisher a bit, and apparently SegmentCounter claims I saved 53 frames? Well, okay. I haven't put time into analysis for the difference, I'm just pulling together a nice start before crunching down more for optimizations.

Just to check, SegmentCounter script claims I enter the end stages at frame 62901. The script also claims Team 4 got there at frame 64957, so 2056 frames ahead of the leading team. I'm not fully satisfied with this stage, particularly as I have not investigated Team 5's rather swift Segment 8. Again, I just threw this together so I have a better baseline than Team 3 to work off of.

I'm ahead in this first half.

5 frames ahead of T3 at some point, then I lose the advantage somewhere around the final breakables of Segment 1. May be worth checking if T3's route in the area is preferable, though the interaction of the route with bubble barrier and Miniboss Skip might not be good, not sure.

The skip itself needed a delay for flame charge, as I don't really see any way to avoid hitting the enemy's back. Can't think of any good ways to strike it remotely.

Charge Swap Bubble Barrier proves its worth once again on the ascent. 1 HP remains when I ended the movie. For some reason, I'm thinking taking damage might be preferable at one point, for Charge Storage in the upcoming segment. Are my thoughts any good? Low on flame ammo.

=== END OF STAGE 3 (Frames: 5709) ===

Saved a dialog 8-frame rule. In turn, I removed the intentional 24 frames inserted between stages, as now we're lined up on the item drop 32-frame cycle. Nifty how planning things out based on a frame rule can let me work on a later stage and get things to sync with zero trouble, so the overall movie file is 32 frames shorter. Well, 33, since I dropped a lag frame.

Saved a frame on miniboss entry, thanks to a suggested pixel. The transition to the down segment afterward was not playing nice, and after many trials, I finally found a result I like. Item drops approved of this, and I got through with minimal pain, other than a single lag frame (down from two). Stage 3 is now nice and smooth.

I suppose I'll take on Stage 2 next. Not a lot of choices left.

Almost the entirety of this stage was taken from Team 3, then improved on where it looked possible. Team 4 was used for Segment 1. I re-did the boss with the closest thing to zero effort without copying any movie, I recommend applying entertainment. Unless you think seeing the player not really bothering to do anything except hit boss on earliest frame to be entertaining.

Charge Swap Bubble Barrier was abused to the fullest extent, once more. This let me ignore some damage Team 3 was stuck with. Changed up the laser on the miniboss so that I lose only 3 barrier HP to it, by being further left and having it finish the laser a few frames later. Didn't need to do a lot of item manipulation, it seemed as though this stage doesn't need a lot of ammo, though Flame Charge still needed some. Nice to see I'm decently ahead of Team 3.

Frame rule does not impact this boss. Will use motions based on when it first appeared, not based on dialog, and there is a rather long invincibility move done at some point.

I cast barrier again. Beats Try #3 by several frames, and is also in a good spot to dash at the end. When the movie ends, I'm at 1 barrier HP. Miniboss ate 4 of the HP.

24 frames are inserted between Stages 3 & 6. This is in anticipation that we save a dialog frame rule in Stage 3, I hope. If we don't save it, I will re-order the stages and try Stage 3 with a different frame count.

The Flame Charge at the end of this movie shows what happens when you hit a rapidly respawning enemy. Shrapnel shower.

Well, now I'm done producing a status panel. Contents:
  • Barrier info, including HP and damage timer
  • Weapons, which ones I have and how much ammo. Negative display, too
  • Charge. Accounts for Arm Upgrade
  • Misc. info: Player state, damage invincibility, object invincibility, Heart Tanks, Ammo Tanks, and part upgrades
  • Map, boss, miniboss info, taking over the same spot depending on who's there

Well, I don't know how much realtime info I can put in there that makes sense to do so. I'm hoping the status panel is pretty, its intent is to feel like I'm giving useful information that can be understood, for the most part, without having to pause. The precision depicted is not useful for TASing, and it's not as though the information is all that vital, either. But hey, it's pretty. It's interesting. And it lets you know how much of each weapon I'm using.

13 frames better than my previous.

Removed a mistake in Segment 2 where I forget to hold Right on the frame I release my Flame Charge.

At the end of Segment 8, there is a ladder and a short wall we can use. This run does not use that route. That wall crawling spiky enemy likes to shoot spikes. 5 at a time, in fact. This is very laggy. Yes, I jump straight up to this one, but the lag is not as bad as I saw in the alternative route, if I want to keep screen X position 80. It is possible to avoid having them shoot in the alternative route, by taking advantage of the odd-even parity in position, but X position 81 is very bad at the door.

It may seem like not all that much. I mean, camera scrolls 1 pixel/frame after touching the door. So how can 81 be so much worse than 80? I'll tell you. ScrX 81 vs. ScrX 80 is greater than the difference of 2 lag and 2 normal frames that alternative route gives us. The boss spawns much later sitting on that one pixel. This pushes us back behind the dialog frame rule. We lose the frame rule. We lose all gains and then some from one pixel. Vicious.

Or maybe I do take the route. I obviously have a bad memory on what I did. Took me a while to realize what I uploaded. The times are correct, just that I thought I did one route. I am confused.

Alright, here's what I did: I jumped that tricky route, got to screen position 81, because being in 80 would trigger the enemy's attack and lag the game hard. Then after the next segment loaded, I specifically moved back and forth just to set myself in screen position 80 for the door. Despite the frames needed, this is still faster than just taking the door at 81, and I trigger the boss earlier as a result. I don't remember doing this, but obviously I had to have done it, since no one else decided to have a secret TASing session on my laptop. My memory is definitely not perfect.

In other news, I did avoid one spot of damage and kept the barrier so I can get a better spot for the last Flame Charge. For whatever reason, I had trouble with falling through the floor in the transition between Segments 7 & 8, and delaying a frame let me land normally. Curiously, the delay I chose let me avoid a shot that just barely hit me. So the barrier lasted long enough for my needs.

Preliminary look at Stage 5. I'm on the bad side of the frame rule by the boss. Stages 3 & 6 were tacked on the end of this TAS, as proof of concept as to how readily I can just sync stages however I please, though I did need to fix a few weapon swaps.

Bubble Barrier Charge Swap was used extensively, from the start of the stage to its very end. I'm not happy with all 18 hits the barrier took, I can benefit from keeping just one more hit for the end, as I prematurely fired my Flame Charge, landing me on the save platform. It was that or wait out 16 ouch frames. Probably time to look for the least costly hit to preserve.

Still, the Miniboss Skip accounts for 150 frames, give or take 50. I'm 221 frames ahead of the leading team, so at least Miniboss Skip can't really take all the credit from the improvements. I did not carefully compare optimizations between this run and the teams, so this stage can stand for another look over.

Felt nice to just go straight through enemies. I refused to preserve Bubble Barrier whenever it meant I get even one frame of lag.

Removed the stage select delay between Stages 1 & 4. Not only have I found the ammo to maintain a speedy run, but I even removed one lag and saved a frame rule. 24 frames delay inserted between Stages 4 & 3.

Items seemed to manipulate themselves before the miniboss, balancing out exactly with what I had before. The Ghost Fall segments needed some tweaking to get the ammo I need. After that, a change in strategy was needed, and the route had enough rigidity that I couldn't stop the game from producing a bunch of small ammo refills out of reach. Whatever the case, I got enough to reach the end, and the game still had to throw one more refill out of reach when it was no longer important. Somehow, I find this humorous.

I'm more in a mood to look at a stage I haven't optimized. Expect either a fixed Stage 3 or progress on Stage 5. I'm pretty sure anything I do in 4->5 can be readily transferred into 4->3->6->5, as I don't think the weapons in 3 and 6 give any benefit in 5. Probably just a matter of handling extra weapons in the swaps, hopefully 2 frames per swap isn't a major problem in the route.

I'm pretty sure jumping through a ceiling should cause a headache or two. Still, I'm through one faster, and overall now have Stage 7 done 4 frames sooner.

The intentional 8 frames delay between s7 and s1 is also removed. Going through Stage 1 again, I've started it 12 frames earlier, which is 1 and a half dialog frame rules. We were delayed half a dialog frame rule to begin with, so we started the boss 2 dialog frame rules ahead, and so I leave Stage 1 with 16 frames advantage.

That 16 frames advantage is tossed away in the delay between s1 and s4. Stage 4 heavily uses Flame Charge. Item drops are critical.

=== END OF STAGE 7 (Frames: 6062) === (prev: 6104)

Redid a part in Stage 7, then did a lazy-sync to have later stages keep working. The change in strategy here is to trigger the extended invincibility before the miniboss, as an obsolete plan had us do so after the miniboss. The obsolete plan was only good when we still fired the giant laser at the miniboss, which terminates the extended invincibility, but since we're skipping the miniboss now, we can change plans and find better spikes before the miniboss to gain invincibility.

The ceilings after the miniboss room refused to cooperate. Might have lost a dozen or so frames on less optimal ceiling clips. Things just don't go smooth this time around. Anyone who wish to bash their head on this problem are free to try.

8 frames are thrown away in stage select for item drop sync of later stages (the lazy-sync I mentioned earlier), just so I can attach them at the end with zero effort. Under no circumstance is throwing away frames in stage select an advantage for a final run, so this is just temporary for keeping sync. We may want to keep the later stages in case we get further improvements and end up syncing the 32-frame rule for item drops.

Original plan had us get invincible after the miniboss. This was because said plan originally attacked miniboss with giant laser, which has the side-effect of removing invincibility. We don't apply giant laser on miniboss anymore (thanks to skip), therefore doing the invincibility trick before it means we won't promptly lose it on our way through the miniboss room. So, while waiting for skip to become possible, set up invincibility.

These ceilings on the upward segment are giving me a lot of trouble, which is why I haven't uploaded a completed Stage 7.

Don't care what the numbers suggest versus my try #2, I started the dash after miniboss later. Also, extra lag, so no idea about the frame rule effects.

A route where I move to the right sooner. Sadly, a bullet clipped my toes by precisely one pixel. This is enough to eradicate an entire HP off the barrier, and the miniboss strat suffers badly from it. One pixel can do that.

My second attempt at getting to the miniboss in this stage. I still don't feel fully satisfied, even walking to the miniboss with this much barrier. Then again, I have a decent lead over the DTC teams.

The Segments 0->1 transition is better, at least. Did stuff to preserve barrier lossless, so that's nice as well.

I choose Stage 6 next. My route is unique from any team. After this will be 5, 2, then the end.

Copying in Team 3 was not simple, as this route has a weapon in between flame and bubble. Transition of Segment 0->1 is awkward, as the following ceiling clip apparently needs a low enough screen position. Also changed things with Team 4's ascent to go to the right side just before miniboss. I want it to work somehow. Finally, it would really help if I can preserve just one barrier HP for miniboss.

I'm not convinced what I did is fastest. I hate the 0->1 transition, for one thing. I don't feel right about how I moved to the right side during Segment 1, for another. Having 1 barrier HP for miniboss is extremely desired, lastly.

Nifty. Got to the end of the stage at last. Manipulating item drops because Flame Charge is hungry for ammo. I think I got the items cost-free, as there were a few points I had to delay for Flame Charge anyway.

Copied Team 3 after miniboss. Took a look at how Team 7 started Segment 7 and disagreed with it. They decided to use an enemy there to try that Charge Glitch, which is why their Segment 6 took so long compared to other teams. According to my Segment Counter, I'm one frame slow in this segment, but I haven't carefully studied their route to be entirely certain.

Ascending Segment 8 took an inspiration from Team 3, going all the way left before going up the ladder. This is because the wall is thicker at the ladder, and I can't go all the way left otherwise. From there, I can walljump at a lower height past the ladder. I use Fragile Barrier to get past an enemy, instead of shooting it with fire. This is so I can charge my Flame Charge sooner.

Segment 9 is reported rather slow, probably because we start essentially on the far left rather than whatever place on the right the other teams were. Haven't looked at them, but the frame counts of Segment 10 indicates they paid a rather bad trade for that.

12 frames better than my free form. I practically copied in Team 7's segment in, with only a minor change to make the breakable wall look less ugly. I'm now a cute 2 frames ahead of Team 7 comparing Segments 2 & 3. It's probably because of the camera, if nothing else.

Team 4 didn't need to jump and snipe an enemy, which is why their Segment 3 is so short. I have no plans on matching that frame count with the enemy snipe.

Been distracted on F-Zero stuff for a bit, why I haven't worked on this a bit for days.

That first flame charge Team 3 did wasn't ideal, so I dashed straight off rather than jump and made sure I landed on that platform ahead properly. Segment 0 was otherwise copied straight over. Ran free form on the remaining segments. Segment 1 is pretty fast when absorbing 6 hits thanks to barrier.

My free form had results in Segment 2, apparently. However, my Segment 3 is worse than any team out there. I clearly need to check on a few things I might need to do differently.

I'm not certain Stage 3 is the ideal next spot, but I did get here losing zero frames to animation frame rule. Team 3 got here after exiting Stage 2, and I needed to do adjustments to sync their Segment 0, as they lost 3 frames to this very frame rule (my SegmentCounter script does not count frame-ruled starts against any team, so these 3 frames are not reported; the 3 difference it is reporting was from that first flame charge).

Run out of flame ammo, fall, die. I don't think that was part of the plan.

So I was looking at how Team 5 did things, since they are several frames ahead of the leading teams in this latest segment I die in. Yes, it does appear that throwing Flame Charges in an area that looks ideal for just straight dashing is indeed faster by a few frames. Probably because I'd otherwise have to wait until I land before I dash, and also that a ground dash requires a few frames of us holding still and lasts 40 frames, while there's plenty of time here to get a Flame Charge up and ready.

Item drops went up in importance here. I suppose someone should start searching for convenient items.

Team 4: Leftward position after Ghost Fall

Interweaving the best of teams one right after another. A frame was spent before the ladder due to even-odd parity of X position, as 208 got me hit and couldn't go further right, but 209 was safe, and I get there from 207. While falling, if I'm on even numbers, I can't switch to odd numbers as movement goes in blocks of 2.

Lag on the flame charge at the end of this Ghost Fall. Naturally, I'm not liking this lag. Somehow one frame shorter than Team 3 on the Ghost Fall segment, probably due to the fall cycle. While falling, the player's air time counter oscillates between 34 to 42. One of these frames has 0 Y speed. Probably the cycle was different from Team 3 from the ladder headbonk.

Finding it tough to find time, largely due to life stuff.

Well, saved 13 frames before the miniboss. Discounting that, taking the Team 3 route through the miniboss has us dropping three frames for animation stuff to sync miniboss. Assuming we didn't need that delay, and the miniboss follow-up with that save platform can't be done with Team 4's miniboss strat, our net is Seg1:-14 Seg2:+19 Seg3:-7, or -2 frames. The difference is razor thin. I would advise myself to look a little deeper here.

Changed when I took damage from some fish. I noticed I was delaying just before a wall. So I took damage earlier, so when it came to those spikes, I would lose invincibility sooner and get more damage from there. In turn, because I took damage earlier, I didn't travel as far, and therefore no longer delay at a wall.

Ghost Fall has a good ammo drop at the moment. Further improvements might lose that. We'll see what comes if I continue.

f30961 - 6 frames ahead of Team 4 (x1733, flame charge timer at 2) f31813 - 4 frames ahead (lost 2 frames) (x3861)

The x values I'm using are the white numbers from my script, which is the player camera offset plus the camera position. The cyan numbers from my script relate to player position, except they are apparently whatever was last used for terrain collision, and are less "true" to the player's location.

f30450: Injected Team 3's input. Under scrutiny, I spotted that they were stopped for one frame before the flame charge prior to the breakable. I fired the flame charge one frame earlier in response, for a frame.

f30600: Following Team 4 right after, I was crashing into some nasty lag. Changed strat for flame shot at offending sub. I can change shot timing to refill ammo (+3), but I also get one lag frame.

f30800: Decided to delay jump as long as possible.

f30961: Chosen moment of checking optimizations (1733 by white number). Team 4's run is 6 frames slower to this point.

f31340: Pause refill advanced to this timing. Previously around f31580.

f31813: Another chosen moment of checking optimizations. x3861 by white number, x3885 by cyan number. My 6 frame advantage shrunk to 4 frames.

I left the remainder of the movie in after that moment, but I don't expect full sync.

Ammo is lower at this point, but at least we're synced up on animation frame rule with Team 4. Difficult to tell where changes need to be made between the two teams for the miniboss, so I'm leaving this for now. From what lapogne36 reported, Team 3 was two frames faster between my last frame check and the ladder ahead.

Nothing to report, Stage 4 is identical to Team 4's run. Curiously, whatever changed in prior stages, it all lined up the 32-frame rule and item drops happen exactly as before.

This is in case no one wants to mess around with trying to copy in some team's run. Team 4 is the fastest, though not by a wide margin, and there may be some strategies to mix in from others. I'll make a more detailed post thinking about each team's efforts soon.

Because ThunderAxe31's brain refuses to acknowledge how the back foot pixel works. It's not your fault, it's your brain's fault.

I threw together the ImportantPlayerPixels function in a hurry and all that. It paints tiny little arrows indicating what pixel the game cares about based on the situation. I advise ThunderAxe31 to examine these arrows in frame advance. Since I threw the function together in a hurry, I can't really guarantee its accuracy.

On a side note, this script now sticks the maps into a global variable, so that, once I upload an update to the ExternalRadar, the two scripts will be aware of a loaded map already done and share the resource instead of having local copies. Shame a core reboot kills the global variables, and a reboot is done every time you switch movies. Perhaps good for stability, but makes it problematic if a script has several seconds loading time.

Oh, right. Someone did have a smart loader that grabs only a smaller portion, the one relevant to where you're at. I should track that down, or design my own, perhaps.

Copied Team 4's run. Only real modifications are manipulating different ammo drops and despawning precisely one flame, which saves exactly one frame rule. And, for some reason, a 4 frame delay at the gate, as if we're out of sync of the dialog frame rule by 4 frames. Which is odd, since I don't see any obvious effects from the Stage 7 boss that would change our stage entry here by a multiple other than 8. I will recommend to myself to figure out how the Stage 7 boss ended up different.

Item drop manipulation wasn't too painful, but if we do enter the stage 4 frames earlier, we're going to have to manipulate again. Bah.

We still have +2 lag following the miniboss, but I did get rid of one lag frame and managed to pull together some ammo without lagging somehow. Also fixed the boss, which did apparently require minor edits to have it work, so not a complete resync.

I blame the array starting at IWRAM:7C44, and object data offsets +0x0E (2 byte) and +0x40 (4 byte), for being a malloc substitute for painting sprite graphics. Due to the fact I destroyed a different enemy for my ammo, this somehow caused 2 lag frames later, which was removed by attacking a lag bomb to delay its self-destruct, and to delay a charge so I omit its graphics for just a little longer and avoid the second lag frame. Nice to see removable lag.

Again, I blame some graphics allocation routine involving those object offsets and the array. Probably scans through from the start of the array and works forward trying to find a large enough open region. And the regions are distributed differently from different enemy destruction, probably extending the search and lagging as a result. Or so I suspect.

Yes, T3 has a faster Segment 6, but they don't set up the invincibility. I haven't double-checked for efficient routing, though.

We are landed sooner than T4 after miniboss, and a little further to the right relative to camera. Generally advantageous, as we can dash sooner, and we can always sacrifice camera relative position if it means a better position to shoot the immediate enemies.

This run falls flat against the boss, though. We have added lag in a few spots, we're low on ammo and no lag-free options I can find, and basically in some mess with the overall sync.

Although the frame rule is always the important thing to keep in mind, removing lag are firm savings. One lag removed is one frame saved, since the game's frame counter doesn't increment in lag, and therefore delays the frame rule by however much we lag. I haven't checked our gate frame rule for frames we can safely sacrifice, however.

On top of not having ammo, the initial damage we take from the boss doesn't sync either. Probably a matter of taking close looks between Team 4 and this run.

4 frames delay at boss gate. This is to sync the boss, and even if we remove this delay, the dialog frame rule gets in the way, and not one frame is saved even if we redo the boss. So the gate delay is an easy sync that doesn't cost time.

Our s8 is now faster than Team 4's s8 by 12 frames. Would be 16 if dialog frame rule wasn't a factor, or we somehow find another 4 frames in intro. Yay ThunderAxe31 for finding an improvement that got me seeking another improvement.

There's probably some obvious mistake I completely missed on Segment 10 or something. Not sure, but we need another 4 frames if we're going to beat the dialog frame rule, though.

Something like 5 frames with a different route through that last segment. This might be the winner of the stage 7 miniboss skips.

There may be a minor frame loss in how long it takes to get into position after the miniboss, but certainly less loss than what the new route gains. I can't put myself any further left relative to the camera.

I'm still hoping a frame is saved in Stage 8, before the 3 frames dropped by the ladder after the miniboss. That would save an animation frame rule. That, in turn, will save a dialog frame rule. And that will collapse the 32-frame rule the start of Stage 7 is based on right now (f24 delay at the moment). Mostly, I'd like to be lazy in redoing Stage 7, and I'm being lazy on the pretense there is a frame to save in Stage 8.

Based on FatRatKnight's ExternalRadar script.

It's a light script that enlarges game screen to show spawning borders and spawning positions without having to create a new window.

I'm sure I could write an even ligher script by writing from scratch, if you need it just ask me and I'll do it.

Nifty. Thanks Dacicus for figuring out the perimeter bounds.

The corner boxes only apply if you're moving diagonally in that direction. Otherwise, they are inert and spawn points do not react to them.

Hopefully this addition to the script makes it better at dealing with things decidedly off-screen. It was nice being able to see the moment enemies appear before. Now it's ever nicer to know ahead of time when they will, and if it can be avoided with camera trickery.

I've also added commented lines expecting the other three boxes.

If you want to question the fact I have a function (CanvasSpawnBorders) for the rather specific purpose of painting these spawn boxes, then you should also question my decision for making a function that paints exactly one box (CanvasBorder). My decisions are generally based on what information is being handled.

For record keeping, this is how to skip the miniboss in the intro. Shame that setting this up takes more time than just smashing the miniboss.

We also can't Ghost Fall down the next segment. We're not at the right edge of the screen.

f18781 Segment 4: 69 (T4:236 ; T7: 69)

Segments 2 to 4 in 806 frames. This is 37 frames off of Team 4's no skip, and 28 frames off of Team 7's skip. Also, one laser shot is far less costly than 2 laser charges, so that's another plus over Team 4.

Did not attempt to optimize a version of Team 7's route through, that is, "glue" myself to the right edge of the screen and navigate that way. Might get the helicopter going to the right earlier. Might be too much damage before that slowing us down. Camera will also be worse at the miniboss room by probably 30 pixels, though that might not affect time.

Note that this file delays 24 frames at stage select so I didn't have to get here re-manipulating luck. If an 8-frame rule is saved in Stage 8, this means a delay of 32 frames, except it wraps to 0 delay as the item drops are on a 32 frame cycle. In a sense, this delay is an optimistic one, expecting precisely one frame rule saved (or five, nine, thirteen...).

I really need to keep track of credits for each stage...

Shh... Secrets. Which has no business being secret anyway. Making public any changes once I make them is hardly secret.

Some comments removal (code holdover from the hitboxes script), fixing the enemy coloring (variable name mismatch), and identifying the spawn locations. It will also recolor the spawn spot if it's in use.

The spawns was something I was looking for during the contest, but I didn't find it myself. I suppose I should thank Dacicus (or however the username is typed).

This script shows the enemy spawn locations in the current segment (white squares), as well as boxes that should indicate where the camera needs to be to spawn the enemies. The blue rectangles are the spots when moving right and the green are the spots when moving left. If the top of the rectangle is above the top of the screen, the enemy should not spawn. This does not account for vertical movements (jumping, climbing, etc.).

BK2 begins from savestate

How to skip the stage 6 miniboss. You first have to set up a miniboss state. The enemy used to skip the miniboss probably spawns at (144, 48) in segment 1 of stage 6. Note that you have to backtrack slightly in order to load segment 2 (why I kept jumping up toward the spikes). The doorway to the miniboss is blocked off otherwise.

Well, we did the boss skip in intro. Nifty.

Stage 8 syncs like a dream. Except the boss. The dialog frame rule is out of sync by 4 frames now, which is to be expected after the animation 4-frame rule locked in our entry. I have consumed these 4 frames waiting at the door instead, so the boss syncs too.

This has the 3 frames for taking the second ladder route through Segment 3 in Stage 8. We need another frame, and some way to carry these three all the way to the end (they are discarded at the ladder after miniboss), and we'll beat another frame rule.

Doing this in case someone wants to poke about Stage 8 instead of intro all the time.

Apparently this run is largely independent of item drops, so we beat the boss with 1 HP left.

If we can save that lag frame in the intro without losing the frame rule, this stage should sync exactly as before. Actually, this stage is proving sync stable.

The one change was to take the ladder down instead of ledge clip in the middle of Segment 3. Apparently, this is 3 frames faster than Team 4. The saved frames were thrown away intentionally at the ladder after the miniboss, marked with Select presses, to sync the remainder of the stage.

One extra lag frame during segment transition after the Ghost Fall and jumping off that object platform. Otherwise, it's a clean improvement.

Any ideas on that lag frame, anyone?

I base the name on what frame we can input something on the stage select, by the way.

Shh... Secrets. Stand-alone script.

This script combines the virtues of both the terrain tiles and the hitboxes scripts, but pastes the info onto a separate canvas. The viewing area is 2x of the game's normal viewing range, so we're seeing half a screen out in each direction past the visual boundaries. It's a heavyweight script, so be aware of slowdowns when running it.

The terrain tiles loading is not aware of the tiles script, so if both are running, there will be two copies of the same data loaded into lua. They are several hundred KB in size, so do be aware.

Shh... Secrets. Script #2, intended to be run second.

This script is the one with the hitboxes. All of them, player, projectile, enemies, and items. They are color coded, too. Enemies are colored based on HP, with zero or negative given a vastly different color. Player projectile is colored based on whether it does damage, rather important for the Muzzle Flash I'm sure you're all frustrated with by now. This is what the game was doing to detect all those hits. Also nice to know what's happening with the basic projectile when changing weapons.

Oh, and this script has rescaling, with M and N keys, so we can see off-screen enemies. Only problem is the other scripts aren't rescaling, so... Uh, enough embarrassment, and stand in awe of my ROM diving skills. Finding and then following pointers around can be fun.

Shh... Secrets. Script #1, intended to be run first.

This script paints an overlay on the screen, showing what type each tile is, in convenient color coding. This is what we use to know exactly when air ends and walls begin. Seriously, there are spikes that aren't there in Stage 4, walls that aren't there in the sixth stage part of END, and plenty of floor clips that this script makes apparent very quickly. Also be sure to look for backward slopes in the intro and Stage 4, too.

Note that the script takes a few seconds to load all the tiles into lua tables, as this method means I won't have to do several memory reads to get the right pointer, adjust it, then fetch the right tile. The script is much slower in runtime without this loading step. Also, this required some ROM diving, and I had better hope this thing is useful!

Intent of the script is to state how many frames it took to complete the immediate segment, as well as how long it takes to do the stage. The state machine in it insists that it sees the beginning of a stage before it starts doing its counting. Hopefully, this will make comparisons easier. If anyone has ideas on better measurement points, I don't mind suggestions.

I've commented out a piece of code, around line 145, that would report how many frames you spent traveling at each pixel/frame. The script is keeping track, just that it won't print the actual stuff without that stuff I commented out. It's cleaner without it, but if you want the added information, go find that spot.
