    I've noticed that I've been missing dash forwards (walk occurs instead) equally as often as dashbacks on the new UCF, and I have two possible theories -- assuming I'm not crazy. Please at least consider that what I'm saying might be true. 1. With a character like Sheik, because you want to "flick" the stick rather than "holding out" the input when you dashdance in order to perform her foxtrot dashdance without entering run, I've experienced issues that many other players wouldn't have happen to them, and maybe the new UCF has changed this from the previous version in some way, or that the 1.0 "clamping" code has messed with this in some way 2. The 1f buffer for executing a dash out of lag has possibly been removed or compromised in some way. I've been entering walk very often especially when trying to act out of lag, and it's possible that my previous muscle memory is producing different results. I've experienced this dashing issue on Dolphin and CRT with 0.84, and with the input integrity adapter I've ensured that visually my netplay setup's latency is extremely close to that of a CRT setup (within 2ms). I've also used various controllers (PhobGCC, OEM), with different stickbox springs in new-condition stickboxes as well as ensured the health of their potentiometers (for the PhobGCC, replicated the waveforms to that of a healthy OEM), yet still have had issues dashing. Some other various things I've felt have been off: Shielddropping, especially when using the buffer for doing so, seems to cause a spotdodge instead, especially when done out of shieldstun. Several other top players (Zain, Ginger, Krudo) have corroborated this, but obviously it's just our opinion. When trying to shield tilt, I've found that I've been rolling instead. Perhaps the old version of UCF made it easier to do so, and I've developed muscle memory according to that. Even if all of this is placebo and I'm completely wrong about everything, I would say it is extremely unwise and downright rude to enforce and switch to a new software right before the biggest tournament of the year, and have Slippi Dolphin adopt it only 2(?) days before said event. Even at Mango's Genesis bootcamp, all of the setups except the main stream setup were on UCF 0.8, not 0.84. Everyone has been practicing on a different game. Changing the game right before the biggest tournament in the world is extremely rude in my opinion. I know 0.84 was said to have been beta tested by the public at regional events for the past year, but let's be real -- 99% of players would not think to blame the software if they missed a few things. I also am the world's most-traveled Melee player. I went to ~30 tournaments all across the world in 2023, and all of them used UCF 0.8, not 0.84.

    • @pablopa_SSBM
      @pablopa_SSBM 6 หลายเดือนก่อน

      Have you tested all these things in UCF 0.8 using the same setup (same controller, same console, pc, etc)? having said that, I agree that it was whack to have slippi/UCF updated a few days before genesis

    Nice vid! Technically, controllers send unsigned bytes for stick values, which are converted to signed ingame. I.e. values from 0 - 255, 128 corresponding to signed 0 ingame (if controller is exactly center calibrated).

  • @CarloVaccariPlus
    @CarloVaccariPlus 6 หลายเดือนก่อน

    To be more precise, a barely-missed dashback doesn't give a slow turnaround, it gives a few frames of slow turnaround and then dash. It's harder to see but still very impactful.

    • @JonnyGamble
      @JonnyGamble 6 หลายเดือนก่อน

      This is true! Also even in “reubicar Meele, you have two frames to buffer a true 1F-turnaround dashback out of many lag animations such as throws. In vanilla/regular, dashback was inconsistent out of stand and aerial landing lag (with the latter being significant in my opinion).

    @gusgarrison9211 6 หลายเดือนก่อน

    I appreciate the proof that 0.84 dashbacks are working as intended via the stated definition, but I slightly disagree with your methodology. Imo you should have included a tournament using a prior version of UCF in the testing as an additional (and granted, redundant) control. Additionally, the claim by people seems to be that "0.84 dashbacks are giving slow turnarounds more often than older versions." In my opinion, the best way to falsify this statement would be by comparing the rate of slow turnarounds rather than successful dashbacks. It's possible an older version may have been giving dashbacks when it should have been giving turnarounds. I'd be interested in seeing someone break down how many slow turnarounds happened in this same recent 0.84 major, listing what 3-frame series of analog inputs led to that, searching for those same permutations in an older major, and comparing the outputs. Love the work you do! Stay hydrated!

    • @2600AltF4
      @2600AltF4 6 หลายเดือนก่อน

      Alas, there's only so much I can cover before the video becomes an hour long. One thing I considered covering but didn't was the chain of events your inputs take until being consumed by the game. The point there would be that UCF has nothing to do with the creation of the raw inputs, as read by the game. If the allegation is that your RAW inputs are suddenly different, then that really has nothing to do with UCF. Still, it might be interesting to see a slow turn / fast turn ratio across different majors. Perhaps I'll look at it.

    @vurj 6 หลายเดือนก่อน

    Does the physical "wiggle room" of a controller have any impact on the games deadzone? I thought it was purely a mechanical degradation in the stickbox. Isn't the distance from the center, as read by the potentiometers, still the only thing that affects the deadzone? If you used brand new potentiometers with a loose stickbox it would still have no pode and worst vanilla dash back right?

    • @FishamanP
      @FishamanP 6 หลายเดือนก่อน

      _as read by the potentiometers_ is the key point here. Potentiometers are reading 0 within the entire wiggle zone. It's unintended hardware deadzone. Very few controllers use optical control sticks, but a very notable one that does is the N64 stick. Indeed, a very loose 64 stick flopping around will send input to the game.

      ​@@Cmanorange In a lot of ways it would actually make the game better. 1frame dashback is really broken for characters like marth and fox. It would also get rid of tech like dash back out of crouch and smash turnaround bair which are really annoying to execute and very strong.

      what makes you think slow turnaround is intended and 1 frame dashback is the bug? I would argue starting a slow turn around animation (that's also when you tilt the stick slowly) then cancelling it after a few frames into a dash is the more strange and buggy outcome than just dashing backwards on the frame you input it like dashing forward
