Karl Jobst, if I was the first person to ever beat a Quake speedrun blindfolded, do you think it'd be worth a video? You unironically would be motivation enough as one of my favorite creators to try and pull it off. Incidentally I found a (now banned) credits warp strat (involving what you could consider ACE?) in Quake that beat the WR in about 40 seconds using the poorly sanitized name console command to change my bounding box size, to clip through the floor in the start area to skip straight to Shub. Sadly they thought the strat defeated the spirit of the run, and made it a meme category, before deleting the extension entirely. :c So this would sorta be my attempt to have a first run that WOULDN'T get deleted, because I think blindfolded Quake runs could really catch on like they have for SM64.

Thanks to Karl Jobst for featuring this recently discovered ACE! It was very enjoyable to help on this. A few things I'd like to address that I'm seeing some people wondering about: Q: Is the discovery of this glitch marking the "death" of this speedrun? A: Not at all. As mentioned in the video, this was made its own separate category, while ACE is banned everywhere else. The speedrunning community at large still favors the main Any% categories which do not use ACE. This is seen more as a fun novelty so to say. Q: Why is the time that it takes to acquire the save files not included in the final time? A: While it would be nice to not rely on any pre-existing save data for this, it's impossible to completely reset the save data to a clean state on an original disk anyway, because this game also memorizes a "High Score" without offering a way to reset it (global across all 3 save slots, never even displayed anywhere which is kind of odd). If someone wanted to rely on a different setup that doesn't make use of the save data from playthroughs on other slots (which does exist and involves using object X-coordinate data, but it's not RTA viable atm), then based on current knowledge they'd need to use the High Score and Current Score as part of the setup (as those are the last things that would get executed as code with this setup, before the game would pretty much inevitably crash). If using those save slots was disallowed, it would create a situation where someone could save too high of a High Score on their disk and "brick" their disk in such a way that they wouldn't be able to pull this off at all, which is kind of undesirable. Of course, there's external ways to rewrite the data on the disk, and it's easier to just clean save data out if playing on emulator or on flashcart, but then it's kind of a whole thing to have to do. It was easier and more practical to just allow those saves to chill on the disk and do the run :) once they're there, you can grind runs out forever so long as you never overwrite the first two slots.

Yes, there was less memory, but as someone who has worked as a game programmer, I'm pretty sure this glitch was avoidable. A few options: The countdown after taking damage could have stopped at 0 instead of -1. When you trigger the scene transition, you could set the variable to 0. And just in general, I don't know about Castlevania specifically, but there are some NES games with shockingly bad coding. Like NES Tetris, the score you get is multiplied by the level, but instead of using the built in NES multiply function, it implements multiplication by just adding repeatedly (causing the game to sometimes crash at high levels when the repeated addition takes too long). People have gone back into the NES Tetris game code and optimised it to the point that they can run it at several times normal game speed without crashing, so...yeah, code from the 80s can definitely be improved upon. Obviously Castlevania had to deal with limited memory, but it's very likely there were tricks they were not using that would have used the limited space more efficiently, and which would have avoided two different systems fighting over the same variable. For example dividing up the variable being used here so that a couple of the bits are responsible for one system, and a couple of bits are responsible for the other system might have worked.

I’m glad they made it its own category, there used to be a lot of dumb hang ups that ruined some other games and runs back then, but it should’ve always been kept this simple with new categories. Beating it 76 times for 12 hours, to set up some internal value to get a credits warp… it’s so wild and strange, speedrunning is always amazing in many different ways.

So basically the jump platform is necessary section like elevator in modern games? So cool.

I called this the "Glitch Room" in my walkthrough of the game, and gave an explanation of how it worked. But I didn't know the FDS version brought you to the Ending. I also like the glitch that makes a money bag appear below a platform, outside the Mummy boss room. It tyook me a lot of attempts to try and solve that one. I eventually had to use a emulator and several Game Genie codes to reach it. There are also parts of the stage that scroll further, but you'd need to be able to jump in midair to see what's at the end. I named the video "Castlevania 1 NES, Bonus Item Locations, Unreachable Areas, and Glitch Room" it also shows the location of the Bonus items for first and second quests, such as the Moai heads, and a few other fun wall/roof glitches.

00:50 Well, there have been some examples where ACE was used to overwrite the game with a completely different game or even other sorts of software altogether; so in a certain sense, it's useful even in some situations where you do completely break the game.

It makes sense to put this in its own category. You could even argue that his run has taken the 12+ hours he took to set up the save file plus the timed run performing the glitch. But it is very interesting to see how the values in the save file can affect the game - which lends itself to experimenting with other NES/FDS games.

This stuff is just absolutely fascinating and the depth of knowledge needed to even piece this type of stuff together is amazing. Seeing all these games we grew up with getting broken by code manipulation all these years later is so cool.

This reminds me a bit of the missingo glitch from pokemon. The game dumps the players name and (iirc) pokemon into map tiles during a cutscene when the old man teaches you how to capture pokemon. The game basically made a cutscene to show how this is done. But due to limited resources, your trainer info and pokemon data has to go somewhere. For some reason, the programers chose map tiles for wild pokemon encouters. After this cutscene you can fly to (iirc) cinnabar island, surf on the east side map tiles and meet missingno. and other glitched pokemon. I wonder how many more old video games can be broken like this?

MissingNo was actually one of the first if not the first I heard about way back when. It started as playground rumors concerning shiny Pokemon - they thought they were called "missingno" Pokemon. Super interesting.

ACE is definitely the Holy Grail, but historically it's considered the death of speedrun for glitch% runs. I remember when it happened "recently" to OoT and MM, almost everyone just quit, both runners and viewers. I think it was also the death of SMB3 glitch% runs. It's just kinda boring to watch, after you've watched it once you've seen it all.

Just a random guess, but maybe using the whip while jumping resets to a different number vs using it while on the ground because Simon will not stop moving if he whips while jumping, but he pauses while using the whip on the ground.

you broke 1 mil subs!! CONGRATS!!

Even if the any% were to be in the running, i would say that keeping the 12+ hours to setup the ACE should count towards the time, meaning any% should be safe. Then the ACE ruleset just says 'ignore the 2nd file setup'

More advanced Memory Management Controllers took most of the beneficial features of the FDS and allowed NES cartridges to run the games and include most of the features like, again, saving. MMC's also mimicked the extra storage space of the FDS by using memory banks. This allowed games to exceed the addressable memory limit on the NES by swapping memory blocks in and out.

There is an argument that setting up the save files is part of the run, since speedruns are typically intended to be from fresh saves to credits. However, the community seems to take tge position that it would just be pointless then and not including the save setup results in a more enjoyable experience. I agree with this.

Yes it is understandable else no one would probably run it except for maybe Wolf himself. There is a secound setup thought , and if i understand it right it uses a secound controller to execute the code , instead of setting it up with save files.

We'd never have known this was possible if the devs knew to put a clone version of the substage at the 255 value. You'd never notice it wasn't the actual substage 0. Pretty interesting how it all plays out.

A speed run in a game that makes you walk at a snails pace must be incredibly frustrating. Hats off to those with the patience. It would drive me nuts.

Ethically speaking, I don't think that counts as a speedrun, because you have to play the game all those times to set up the save data first, so you have to include all the time that took as well. It's like a magic trick, it's just an illusion of a five minute finish, and if it isn't then the scoring rules are what's actually broken here. Interesting data nonetheless.

yeah, it's fair that this became a new category. crazy that they found such a cool thing!

I always thought that the speedrun timer begins with the start of the setup. Achieving that skip is still an amazing feat.

once any speedrun community finds ACE, the run dies Paper Mario 64 for example

They did. 76 times.

Rules of speed running may have changed as I have only be lightly lurking over the last 10ish years. But when I was active, the rules were that a speedrun that requires "pre run set up" before the actual run, the "pre run set up" time could count towards the final time. For games without a reliable built in timer, RTA runs are timed from first frame of character control and ends when control is lost (excluding most text boxes). An example would be DK64 where the glitch used to break the game happened in the game menu before starting the game proper. In that situation, the time starts at power on. Similar to this, would the run time not start on first file character select, continue through the 2nd file runs of +70 game completions, and end when the the last input is made on the 3rd file? Genuinely not trying to start issues, but I was wondering if the rules now allow "pre run set ups" as that would break many game times that we pushed aside as it did not allow for faster times overall.

I think this tends to go on a game by game basis. Different games tend to have different standards. Or at least different standards for what people consider the 'important' category. It's more than likely that this won't be considered the 'gold standard' of Castlevania speed-running. It's simply impressive as its own category.

@@Darenimo Not even a "game by game basis", but a community-by-community basis. The people running the game (and the people hosting the leaderboards) get to decide what "the rules" are. Generally, the objective is to ensure that running is competitive, fair, and enjoyable. Do you count time in load screens? Menu screens? Are glitches allowed? Out of bounds? Can you start from a save-game that skips an intro cutscene, or with a pre-made character? The community, or leaderboard authority, decides all of these sorts of issues. And sometimes, those decisions change over time. Sometimes attitudes change and rules and leaderboard splits will be modified as time goes on. As long as the rules are clear and fair, then competition can occur.

I believe this is the first "ACE" run that needs a set up in this manner as well. SMW, Pokemon, SMB3 can all be done on fresh start ups with no prior saves or pre run prep. This one requires nearly 8 hours of prep before the 6:30 run can begin. That is where my question really is. I could be wrong, but I would say that is pushing the limits of a fair playing field.
