These videos always make me nostalgic for the old internet, when there were entire websites dedicated to discovering and explaining arcane stuff like this about games. What a special thing for someone to take it upon themselves not just to preserve that wacky world, but to make it so much more approachable for so many people who would never otherwise be able to enjoy it. Thanks for all you do, Bismuth.
The final minutes, with that gorgeous piano piece and the world record holders' times and celebrations, the final scene with toadstool, it all adds up so much, Bismuth. The way it closes out without a word, just piano and the text "Thank you Mario! Your quest is over." It feels like you're being told that your hardship is over. It's enough to bring anybody to tears, your worn down and tired, you've grinded away at a possible best time for months, if not years, at a goal. Watching a group of people finally break down a barrier so small yet so important actually broke me down, I cried at the end, but it was without a doubt the perfect ending to something like this.
13:15 The fact that you included that on screen description of why B or something else needs to be held during fast accel because of the “insta stop when speed is in between -10 and 10” mechanic blows my mind, and makes me so happy to see. As of like a year ago, little to no RTA players knew that, and still now very few people know of mechanics like that. It’s ridiculously impressive that you put in effort to learn small details like that, and it’s just as impressive that your able to work in those minor details into a video without it getting too lengthy and over complicated. Amazing work bismuth, this level of detail is seriously ridiculous.
Check out this bit of code, it's the function that checks if Mario should stop quickly. This was done intentionally to make directional changes quicker and feel more responsive. i.imgur.com/dlq1Xyg.png The highlighted line is where the bug is. The game masks out the A button, but reads every other button, and then checks if the result is 0 (i.e. if no buttons are being pressed except for A). If it's 0, Mario decelerates slowly to a stop, and if it's not zero (i.e. if any button is being pressed), it checks if he should be stopping instantly. When it checks if he should be stopping, it masks every button except left and right (03 = 00000011, 1 is right and 10 is left). Then it compares the resulting value with the moving direction (again, 1 is right and 10 is left). If it's the same, that means you're pressing the same direction that you're moving, so you should not be stopping. If it's not the same, that means you're pressing the opposide direction that you're moving, so you should be stopping. But here's the catch! If you were not holding left nor right, but you were holding some other button, the and #$03 returns 0. When it compares against your moving direction, 0 is not equal to right (1) and it's also not equal to left (10). So no matter which direction you're moving, it's not equal to your button presses, and it stops you instantly. This is why it works when you're not holding left/right but you're holding any combination of B, up, down, and select. Technically it should work for start as well, but in practice I haven't found that to work, so maybe something else happens here.
The mechanics of mario are so fun and interesting. I've had some stuff happen before while playing through that seemed crazy and impossible at least for my knowledge, I wish I had recorded them. Probably from that every other frame hit detection thing I learned about in this vid, can make bouncing off some enemies work in strange ways sometimes.
@@Bismuth9 There’s so much stuff I know about for Smb1 that I am almost certain is true and accurate, but never looked at the code to be certain (for example, I have known about this speed between -10 and 10 thing for a long time, but only because I figured it out when TASing and eventually understood how it worked). It would be really cool to be able to check the code to confirm all the stuff I know and understand it all better.
31:11 “while on paper it could be humanly possible, it’s doubtful anyone would be able to pull it off” and now, 2 years later, it’s been done in the world record run. only 8-4 remains
I know what you mean, 8-4 in a full run. For individual levels, two players tied the TAS on 8-4, LeKukie and Niftski. The perfect run can now be combined from 2 segments. Maybe one day the run will be perfect in RTA...
7:04 I still remember when I found that pipe clip thing. When I first went through that pipe, I felt top of the world. It was like....I found some hidden treasure. One sunday afternoon I called all of my friends and showed them. We spent hours doing that and for a brief period, I was the coolest dude in my circle Lol Good old days!
This video is amazing. The "shoulders of giants" section was genius and moving. The whole thing is explained so well, and the visuals are top notch and super clear. Fantastic work as always and well worth the wait.
3:20 "When Mario runs into the wall, for one frame he actually runs into the wall." I would assume he does at one point run into the wall when he runs into the wall. Otherwise, he wouldn't be running into the wall and therefore couldn't be running into the wall.
When you said he stood on the shoulders of the giants and showed the previous world record beating moments, that was truly inspirational! Amazing what humans can achieve when they set their minds to something - just incredible!
I just want to say that the animations comparing two different ways of doing things (EG: grabbing flag VS glitching into the block) really makes the small differences very apparent. I likes 'em.
I've seen enough videos on Niftski's record where I thought I could really skip this one, but the impeccable visuals with counters and overlayed comparisons are just so thorough that I learned way more from this video than I would have expected. Amazing vid
I’m super pumped to sit down and watch this. I feel like it’s going to be a good conclusion for me. I love this community, it’s runners, creators, and watchers. Thanks for all your work, bismuth. You’ve helped bring so many people into our little community
26:30 this section seriously made me well up. To see so much hard work finally pay off as each of these players takes their moment in the spotlight as the greatest player in the world, and their sheer joy and excitement. It's beautiful.
Bismuth, the segment at the end where you show all the ghosts of previous runs with the previous WR holder reactions brought tears to my eyes. So well done! It really goes to show that for a game like this, every new achievement really does build on all the history that has come before
@@iluvdawubz no real beef I assume just playful jabs. Edit: crap... I just whoooosh myself. I was half asleep when I replied, i totally didn't see the playful sarcasm 😂🤣😂🤣😂
Man this video is so good, the amount of info in this is insane and we thought the old videos were already well in depth. But like you said this is probably not getting outdated unless a miracle happens and a completely new timesave is found but... That's just not a thing right now.
I'm a month late to this, but after Miniland beat this record with a 4:54.914 (yes, on an actual NES this time), Niftski took it back with a 4:54.881 on December 2nd, 2021! Watch the run here: ua-cam.com/video/aukKeS8LdDI/v-deo.html
also Niftski has gotten 50+ Lightning 4-2 framerule saves, including one in a run -- he said that he can get it roughly 8% of the time, so he'll be trying repeated runs with it soon
The production quality of this video is stunning, and the explanations of what is happening are the clearest I've heard. Nevertheless, I continue to be amazed that human hands can execute such feats of precision, and it's a testament to the dedication of players themselves and collective accumulated knowledge of the speedrunning community. It's amusing that a new generation remains so interested in keeping this classic game alive. Perhaps it is because, despite its simple appearance, the game's mechanics are relatively complex. I have fond memories of playing Super Mario Bros. with my best friend all night during sleepovers. Three decades later, we're still good friends, and the game still makes me nostalgic for those simpler times. P.S. As a pianist, I would pay good money for the score to the background theme music.
Making sheet music is quite time consuming, and so I don't do it unless I played it a tempo closely enough to be able to convert it into a readable sheet music in a few hours. I would have to either make it from scratch, or somehow turn this into a readable score. i.imgur.com/MyKBTwO.png
I was born way after SMB1 but it's one of my favorite Mario games because like you said, even though it's a simple game there's also a lot of complexity if you dig deeper.
But- but these buses leave every third of a second, they must be fast... Why not take one directly to 8-4? Why walk all the way? Man, these speedrunners need less brawn and more brains. I mean Mario should really get hooked with a bus pass.
This was an epic breakdown! Well done! When I was playing this back in the 80s I would have never guessed it would ever have been analyzed like a physics proof 35 years later. 🤣
Amazingly done video! The detail, the editing and the music! And I actually never even thought about Speedruns ever. Still this video to me is truly one of the most memorable ones on this platform
The current world record is 4:54.631 by Niftski. He has tied the TAS to 8-4 and is now 22 frames off perfection. Watch it here: ua-cam.com/video/Khu9BB2g4Ks/v-deo.html
I bet in 10 or 20 years the best time will be 4:37.769 because it will never be perfect so some one will eventually be like omg something new and beat the game a lot faster
@@nintendolegend5344 no matter what people find, the time will never go down THAT much. At most, it could hit 4:50s if some crazy discoveries happened.
This is literally the best video in youtube. You explain all of the tricks down to the tiniest details and in the perfect way for everyone to understand. Thank you very much for this master piece!!
I’ve watched this run a dozen or so times and I’ve watched a lot of breakdowns, and I still learned new and interesting things about the game and this run from this video. Kudos for that.
I’m in utter awe at how amazing all of your visuals and investment to explaining things is such depth and simplicity thank you for the absolute service you’re doing (also for the beautiful piano renditions you play)
Thanks for breaking this down and explaining it so thoroughly. I loved the montage of happy footage of each person who broke a big record along the way.
This is by far the best video I've seen explaining the tricks of these top tier speed runs. I've known about the FPG and frame rules but never understood exactly WHY they worked until now. This video is so awesome.
"A number of fireworks equal to the final digit of the timer go off when the final digit at the end of the level is 1, 3, 6, or of course 0" You are technically correct. The best kind of correct
I'm so impressed by this video, your attention to detail, great explanations and incredible "on shoulder of giants sequence", it all just blow my mind. I didn't known anything up to this point about Mario speedrunning and I understood everything you said, which just goes to show how good this video is. On the last note you're voice is perfect for this kind of video
It's pretty crazy how it works. His popoff is a good 10 or 12 dB lower than the peaks of my voiceover and about 6-8 dB lower than my average volume and yet it still sounds louder somehow
There are multiple reasons it's not possible. Notably the fact that you can't manipulate the RAM significantly without being able to move objects on both axis. In SMB1, the only way to do that is either Mario himself, or having an enemy or object walk off an object. This doesn't allow movement up though. This also implies that there is a way to warp to the Peach animation
I know it's been researched to death and found its almost impossible already, but I really wish it's not possible. I don't dislike the speedruns that make use of it, but I think one of the beauties this run is that despite using a bunch of glitches, it plays out the game almost just as intended. Ofcourse I know there will be a no credits warp category if it's found and is also likely to be the more popular one.
People claiming Niftski has some advantage with emulator ignore two important things: 1) the techniques for allowing humans to setup tricks like FPG were developed around using a NES controller. Niftski has to finagle his own input method to make these techniques similarly convenient. 2) he's using an LCD, as opposed to a lagless CRT. Having to compensate for both input lag and response times when performing frame-perfect inputs is unquestionably more difficult on Niftski's setup. Of course, take any top level runner using a console/CRT combo and they'll be terrible on Niftski's setup, and vice versa. But all things being equal, Niftski's approach is harder -- that's why the vast majority of runners take the much less convenient route of using original hardware.
Not really accurate. Digital encoding is always slower but lowest latency monitors make that pretty irrelevant. Learning on keyboard might be a bit harder/less intuitive, but you can practice faster on emu anyway so kind of irrelevant again. And once you're at high level keyboard is objectively better
@@Kosmicd12 All fair points. Particularly, the difference between a d-pad and discrete keyboard keys might be especially good for avoiding accidental inputs. I'm not sure the difference between a 'good' modern LCD and a CRT is irrelevant at this level of play, but I'm not an expert, and you definitely are.
I have never been into speedruns but this was a great video, it's fascinating how truly skilled the competitors are to pull these insane runs off. Thank you for the detailed explanation of each step of the run 👍
I thought it was the background music used in most speedrunner videos that gave them the edge-of-your-seat feel, but you nailed it without any music at all! I love this video, thank you for providing such detailed info on how Super Mario works and the steps used by Niftski. Awesome!
Caution, pixel perfect is actually no. Frame perfect is true in most cases. For any random wall jump, 2/5 chance to be impossible, 2/5 chance to be frame perfect, 1/5 chance to be 2 frames. For every wall jump discussed in this video, they are all frame perfect.
For those wondering I think I have the answer. They probabilly intended to make the flagpole go down until it hits the bottom or mario hits the bottom. In fact, that happends on other mario games. They probabilly accidentally made the treshold too low and just left it as an unfixed bug because sometimes when you spend too much time on smth you give up.
It's also very likely that the flagpole base was added after the flagpole functionality, and they didn't realize that it broke the Mario condition. Or, they didn't really like the effect so they tried it without the Mario condition by setting the threshold intentionally too low and liked it, so they kept it that way.
I love watching them break these records again and again but it makes me kind of sad that there’s almost no room left for improvement. Truly incredible they’ve gotten this far!
This being my first time watching an original mario bros speedrun, I am absolutely blown away by the sheer precision needed to do the speedrun, and how close it is to the TAS world record, amazing
Niftski said it's unlikely anyone will ever get a sub 4:54.3, unless we find easier ways to get lightning 4-2 and save time on 8-4. But I think both of these will happen. Remember, we thought 8-2 was impossible, but that's because we didn't know as much about it as we do now. And people will just get better at the fast accels needed for 8-4.
@@ThaAwesome10 4:54.282 is theoretically possible, and people are figuring out how to do the first room falling fast acceleration. This makes 4:54.265 theoretically possible, but it may take millions of attempts across many speedrunners.
As someone that does not watch a lot of speed runs I want to say thank you for both breaking this down in a detailed way but explaining minor things most people that do watch a lot of speed runs are likely aware of.
The golden rule of speedrunning is to never say something is impossible - but with literal decades of examination, I'm tempted to really believe that this is the last second milestone. I suspect even a fuzzer wouldn't find any new glitches. It's kind of astounding the game has been reverse engineered to this degree. Unless cosmic ray bit flips (or holding a radioactive source next to your ram) becomes a standard speedrunning tactic, I think this is it.
Although, if some sort of hardware deficiency is responsible for future time savings, it would be very interesting to see how that situation would be handled on emulator. Theoretically, the emulator perfectly emulates the behavior of the hardware in something approaching a genuine physical simulation. But I doubt emulators simulate the exact details of, idk, RAM timing, or if they do, in enough detail to actually capture bugs found with real hardware.
Niftski clearly has an advantage because he plays on emulator with a keyboard. Oh, wait, what's this? a 4:54.93 on console? ua-cam.com/video/lnZLC1W6yTc/v-deo.html

The final minutes, with that gorgeous piano piece and the world record holders' times and celebrations, the final scene with toadstool, it all adds up so much, Bismuth. The way it closes out without a word, just piano and the text "Thank you Mario! Your quest is over." It feels like you're being told that your hardship is over. It's enough to bring anybody to tears, your worn down and tired, you've grinded away at a possible best time for months, if not years, at a goal. Watching a group of people finally break down a barrier so small yet so important actually broke me down, I cried at the end, but it was without a doubt the perfect ending to something like this.
...and then: "We present you a new quest."
You cried? Get help you need it :(
How the fuck people cry at anything
13:15 The fact that you included that on screen description of why B or something else needs to be held during fast accel because of the “insta stop when speed is in between -10 and 10” mechanic blows my mind, and makes me so happy to see. As of like a year ago, little to no RTA players knew that, and still now very few people know of mechanics like that. It’s ridiculously impressive that you put in effort to learn small details like that, and it’s just as impressive that your able to work in those minor details into a video without it getting too lengthy and over complicated. Amazing work bismuth, this level of detail is seriously ridiculous.
Check out this bit of code, it's the function that checks if Mario should stop quickly. This was done intentionally to make directional changes quicker and feel more responsive. i.imgur.com/dlq1Xyg.png
The highlighted line is where the bug is. The game masks out the A button, but reads every other button, and then checks if the result is 0 (i.e. if no buttons are being pressed except for A). If it's 0, Mario decelerates slowly to a stop, and if it's not zero (i.e. if any button is being pressed), it checks if he should be stopping instantly.
When it checks if he should be stopping, it masks every button except left and right (03 = 00000011, 1 is right and 10 is left). Then it compares the resulting value with the moving direction (again, 1 is right and 10 is left). If it's the same, that means you're pressing the same direction that you're moving, so you should not be stopping. If it's not the same, that means you're pressing the opposide direction that you're moving, so you should be stopping. But here's the catch! If you were not holding left nor right, but you were holding some other button, the and #$03 returns 0. When it compares against your moving direction, 0 is not equal to right (1) and it's also not equal to left (10). So no matter which direction you're moving, it's not equal to your button presses, and it stops you instantly. This is why it works when you're not holding left/right but you're holding any combination of B, up, down, and select. Technically it should work for start as well, but in practice I haven't found that to work, so maybe something else happens here.
The mechanics of mario are so fun and interesting. I've had some stuff happen before while playing through that seemed crazy and impossible at least for my knowledge, I wish I had recorded them. Probably from that every other frame hit detection thing I learned about in this vid, can make bouncing off some enemies work in strange ways sometimes.
@Bismuth oh wow interesting. I never learned how to understand Smb1 code but I should
@@kriller3771 It's definitely a trip. I got my first real taste of assembly language during the SMB3 credits warp research.
@@Bismuth9 There’s so much stuff I know about for Smb1 that I am almost certain is true and accurate, but never looked at the code to be certain (for example, I have known about this speed between -10 and 10 thing for a long time, but only because I figured it out when TASing and eventually understood how it worked). It would be really cool to be able to check the code to confirm all the stuff I know and understand it all better.
31:11 “while on paper it could be humanly possible, it’s doubtful anyone would be able to pull it off” and now, 2 years later, it’s been done in the world record run. only 8-4 remains
I know what you mean, 8-4 in a full run. For individual levels, two players tied the TAS on 8-4, LeKukie and Niftski. The perfect run can now be combined from 2 segments. Maybe one day the run will be perfect in RTA...

3:20 "When Mario runs into the wall, for one frame he actually runs into the wall."
I would assume he does at one point run into the wall when he runs into the wall. Otherwise, he wouldn't be running into the wall and therefore couldn't be running into the wall.
When you said he stood on the shoulders of the giants and showed the previous world record beating moments, that was truly inspirational! Amazing what humans can achieve when they set their minds to something - just incredible!
I just want to say that the animations comparing two different ways of doing things (EG: grabbing flag VS glitching into the block) really makes the small differences very apparent. I likes 'em.

I like the use of Luigi to show different things such as not waiting on the bullet or not doing backwards accel. Makes for good comparisons.

also Niftski has gotten 50+ Lightning 4-2 framerule saves, including one in a run -- he said that he can get it roughly 8% of the time, so he'll be trying repeated runs with it soon
The production quality of this video is stunning, and the explanations of what is happening are the clearest I've heard. Nevertheless, I continue to be amazed that human hands can execute such feats of precision, and it's a testament to the dedication of players themselves and collective accumulated knowledge of the speedrunning community.
It's amusing that a new generation remains so interested in keeping this classic game alive. Perhaps it is because, despite its simple appearance, the game's mechanics are relatively complex. I have fond memories of playing Super Mario Bros. with my best friend all night during sleepovers. Three decades later, we're still good friends, and the game still makes me nostalgic for those simpler times.
P.S. As a pianist, I would pay good money for the score to the background theme music.
Making sheet music is quite time consuming, and so I don't do it unless I played it a tempo closely enough to be able to convert it into a readable sheet music in a few hours. I would have to either make it from scratch, or somehow turn this into a readable score. i.imgur.com/MyKBTwO.png

not this time, lol
Well then mario can’t get to 8-3 by bus lol
But- but these buses leave every third of a second, they must be fast... Why not take one directly to 8-4? Why walk all the way? Man, these speedrunners need less brawn and more brains. I mean Mario should really get hooked with a bus pass.

Just wait until they find the credits warp
Not possible in this game
If they knew, then it would already implemented in TASs
There are multiple reasons it's not possible. Notably the fact that you can't manipulate the RAM significantly without being able to move objects on both axis. In SMB1, the only way to do that is either Mario himself, or having an enemy or object walk off an object. This doesn't allow movement up though. This also implies that there is a way to warp to the Peach animation
I know it's been researched to death and found its almost impossible already, but I really wish it's not possible. I don't dislike the speedruns that make use of it, but I think one of the beauties this run is that despite using a bunch of glitches, it plays out the game almost just as intended. Ofcourse I know there will be a no credits warp category if it's found and is also likely to be the more popular one.
you can't have a credits warp if there are no credits!

People claiming Niftski has some advantage with emulator ignore two important things:
1) the techniques for allowing humans to setup tricks like FPG were developed around using a NES controller. Niftski has to finagle his own input method to make these techniques similarly convenient.
2) he's using an LCD, as opposed to a lagless CRT. Having to compensate for both input lag and response times when performing frame-perfect inputs is unquestionably more difficult on Niftski's setup.
Of course, take any top level runner using a console/CRT combo and they'll be terrible on Niftski's setup, and vice versa. But all things being equal, Niftski's approach is harder -- that's why the vast majority of runners take the much less convenient route of using original hardware.
What stops him buying a crt? Those things are basically free
@@the1barbarian781 NES and Famicoms aren't tho
Not really accurate. Digital encoding is always slower but lowest latency monitors make that pretty irrelevant. Learning on keyboard might be a bit harder/less intuitive, but you can practice faster on emu anyway so kind of irrelevant again. And once you're at high level keyboard is objectively better
@@Kosmicd12 All fair points. Particularly, the difference between a d-pad and discrete keyboard keys might be especially good for avoiding accidental inputs.
I'm not sure the difference between a 'good' modern LCD and a CRT is irrelevant at this level of play, but I'm not an expert, and you definitely are.
I have never been into speedruns but this was a great video, it's fascinating how truly skilled the competitors are to pull these insane runs off. Thank you for the detailed explanation of each step of the run 👍

@@Bismuth9 I misspoke. I meant pixel. Sorry.
For those wondering I think I have the answer. They probabilly intended to make the flagpole go down until it hits the bottom or mario hits the bottom. In fact, that happends on other mario games. They probabilly accidentally made the treshold too low and just left it as an unfixed bug because sometimes when you spend too much time on smth you give up.
It's also very likely that the flagpole base was added after the flagpole functionality, and they didn't realize that it broke the Mario condition. Or, they didn't really like the effect so they tried it without the Mario condition by setting the threshold intentionally too low and liked it, so they kept it that way.
I love watching them break these records again and again but it makes me kind of sad that there’s almost no room left for improvement. Truly incredible they’ve gotten this far!

2030 Mario Record: Saving the last frame

Niftski said it's unlikely anyone will ever get a sub 4:54.3, unless we find easier ways to get lightning 4-2 and save time on 8-4. But I think both of these will happen. Remember, we thought 8-2 was impossible, but that's because we didn't know as much about it as we do now. And people will just get better at the fast accels needed for 8-4.

Fucking fax ☠️☠️☠️
4:54 is PART OF the perfect speedrun
This is truly Legendary. mastering a speed game to the point there's less than 1 second of time save left..
The golden rule of speedrunning is to never say something is impossible - but with literal decades of examination, I'm tempted to really believe that this is the last second milestone.
I suspect even a fuzzer wouldn't find any new glitches. It's kind of astounding the game has been reverse engineered to this degree. Unless cosmic ray bit flips (or holding a radioactive source next to your ram) becomes a standard speedrunning tactic, I think this is it.
Although, if some sort of hardware deficiency is responsible for future time savings, it would be very interesting to see how that situation would be handled on emulator.
Theoretically, the emulator perfectly emulates the behavior of the hardware in something approaching a genuine physical simulation. But I doubt emulators simulate the exact details of, idk, RAM timing, or if they do, in enough detail to actually capture bugs found with real hardware.
Are you suggesting rowhammer as a speedrunning tactic? 😄
Are you saying Todd Rogers will be the first to get 4:53?
