Submission Text Full Submission Page
This is the new fastest SMB2J (The Lost Levels, FDS) "game end glitch" (ACE) tool-assisted speedrun (TAS), improving upon the previous TAS by 9 frames, through optimization of the final room in World 8-4.
In March, 2025, LuigiSidekick accidentally crashed the game in 8-4 and posted it on Twitter. Simplistic6502 verified that there was ACE potential. Threecreepio made the payload approach, and web2000 made the first full TAS.

HappyLee's Comments

Recently, I tested ACE in this game for the first time, and discovered the 9-frame improvement in 8-4. Since I wasn't familiar with ACE, most of my time was spent learning its underlying principles.
In simple terms, the glitch works by loading the long Firebar twice to overflow the enemy slot value, creating an enemy with ID $84. By taking damage from the Firebar in lava, and combining 2P controller inputs with the X positions of two fireballs, arbitrary code can be executed to end the game early.
8-4 is currently the only known location in this game where ACE can be triggered. This run is 19.25 seconds faster than the fastest any% TAS, but ACE and non-ACE runs are considered separate categories.
Most of the entertainment part comes from my 2017 TAS, with minor adjustments by me and web2000. Don't miss the wall clip in the third room of 8-4 - it was an idea I discovered in 2018. Coincidentally, it reaches the pipe at exactly the same time as the previous upper-route turnaround drop, so I never had a practical use for it - until this TAS.
For more information about the ACE glitch, please read web2000's submission.

It's been over a month, and still "new". As an improvement over a published movie, this should be almost automatically accepted and published.

It changed from 20 days to over 30 days. What an "improvement". I don't like waiting in the Submission Workbench forever. No TASers would like that.

We lost a third of our judging team before this submission was even available to judge. Be patient for once.

I hate to butt in, but the others have a point; just because a submission is New doesn't mean it's gonna be ignored forever. It's still up for everyone to see, and everyone's well aware it's there. It's just that the judges haven't found an appropriate time to take it into consideration and get around to judging and (eventually) publishing it. It's all a matter of patience from here.
  • I'm dealing with my fair share of waiting as well, at least on my submission, which has been in Judging Underway for exactly four months (though I'm sure it's for consideration reasons; no rush, feos)
  • Here... If it makes you feel any better, Igor hasn't had his SMAS:SMB3 "debug code, playaround" submission past the initial New state, and it's been 3.5 months.
I hate waiting too, HL. But we gotta do things we don't like; things will definitely work out better if we don't complain.
*sigh* That said... Yes vote; great work as usual to the authors of the previous "game end glitch" submission, and, of course, HappyLee and web2000 for their efforts on the entertainment, even if much of the run is similar to HL's 2017 "Mario" TAS. I'm sure at some point we'll have a run that achieves the game end glitch with Luigi as well... maybe? (assuming it's the same strategy as with Mario) Not pushing it though.
I try to check in whenever possible, at least when I'm feeling it. Look out for yourself and each other; there's quite a bit going on.

Probably because your submissions are new Flash games that hasn't been on this site before. But waiting for over two months for the submission still sucks. You have every right to complain about it, but you choose not to, so what can I say, wish you all the best.

NO. 99% of the inputs are mine, and I found the new improvement. Please read the submission text.

HappyLee, you have not provided any specific reasoning as to why this wait is actually problematic. You have no other submissions on the workbench. Plus, if as you say, this is a simple improvement (thus not involving any potential rule/site changes), then there's no reason you can't continue working on more TAS projects in the meantime. We've been over this with you before. You weren't able to provide specific reasoning back then either. Complaining about how long it's taking to judge your submission isn't beneficial for anyone, and continuing to complain after we try to address it with you is only going to make the situation worse. Making a stink of how long you're having to wait is a waste of both your own time and ours. This is a warning. Stop with your baseless complaints. Your impatience is only causing problems. If however you'd like to constructively discuss methods that may speed up judgements without negatively affecting our staff or reducing the quality and variety of content we curate, then we'd welcome that.

It's not "baseless". My complaints is about having to wait over a month for a TAS with no problem or controversy, and that's a FACT. As a site Moderator, you should do better, instead of being bossy.

Do I really have to "provide a specific reasoning"... As I said, no TASer would like their work being ignored for a long time, or waiting endlessly to get a verdict. At least I don't like waking up every day and check to see any update with my TAS in the submission workbench, and wonder what happened with TASVideos and why the process is so slow.

We have fewer judges (as Samsara already mentioned, we lost 3 last month), yet we have more submissions (90+ in the workbench right now, 80+ not yet judged), for a wider variety of platforms and games, making them more complicated and time-consuming to judge. Given these points, it's not that hard to see why it can take a long time before submissions get judged. It's not ideal, but that's the reality of the situation, plain and simple.

Yes, Samsara already mentioned that, and I see why now. But I think maybe TASVideos should seek better solutions, otherwise the line of submission would get longer and longer, and TAS creators like me wouldn't be happy submitting their work on TASVideos. Like, having high standards, so you don't have to publish so many movies every year. And find ways to make the judges' work easier, so more people would become judges.

The problem is having higher standards makes judges' work harder, because more scrutiny is required for every single decision. When the amount of people who can do this is always limited and submission volume increases due to new platforms becoming available for TASing, that only leads to people burning out, on our end. And on the authors' end, rejecting more and more well-done movies only leads to the site gradually losing relevance. Sure we'd be getting fewer and fewer submissions but that'd be at the cost of losing the community itself.

"Baseless," as in, you have not provided any reasoning why the length of time is an actual problem beyond simply that you don't like it. We've tried explaining to you why it takes as long as it does, but you continue to complain with utter disregard of the contributing factors, including the fact that our judges are volunteers, that we've had a significant drop in available judges recently, and that the rate at which we receive submissions has increased. Additionally, attempting to shift the blame to me and insulting me is certainly not going to help improve the situation.

If you want to be constructive, then yes, providing reasoning would help us better understand your issue. Yes, I have seen you make the sweeping generalization that "No TASers would like that." Interestingly, the overwhelming majority of TASers on this site do not make a fuss about how long their submissions take to be judged. So it seems unlikely that your claim is true. Implying that we have "ignored" your (or other TASers') work is entirely false though.

Not necessarily. Having higher standards means you can reject movies based on bad game choice, bad goal choice more easily. For example, there are so many unpopular games & hacks right now, that probably no judges are familiar with. This makes a judge's work more difficult. Or, having separate publication systems, or letting the votes judge, maybe automatically rejecting movies with too few Yes votes in a period of time.

I mentioned 2 factors. When it's easy to reject you lose the community.

Maybe they just quietly leave TASVideos. Maybe they're just too polite to complain. Maybe I'm just too straightforward. I'm on TASVideos nearly 20 years. It wasn't a problem then or 10 years ago, and I was happier submitting my work on TASVideos back then.

Bad game/goal choice in what sense? Simply being unpopular doesn't make the game or goal a bad choice. Basing judgement on the votes, as in how popular or entertaining the game/run is, isn't a good approach. In fact, we've intentionally steered away from entertainment being a factor for years now, which people have responded positively about.

Sometimes they ask about the reason on Discord. We explain it, then understand it, and stop complaining, while still submitting more things. If someone quietly leaves, there's no way to know whether it's because there's a long wait or something else entirely unrelated.

I wouldn't think of it as "lose the community". I remember TASVideos has way more active users 10 years ago, 15 years ago, 20 years ago. But right now, there are way less active users and posts, and people mention that we're losing judges.
