# Story of the Week ✨

**Super Mario Bros.: The Lost Levels** (TLL) is a sequel to Super Mario Bros. It was released as Super Mario Bros. 2 in Japan in 1986 and initially deemed too difficult for the North American market. Only seven years later, it made its debut in the West as part of the Super Mario All-Stars compilation on the SNES.

The best players are already able to complete the game in less than eight minutes, but for the past month, speedrunners and TAS creators of the game have been musing about a new way of crashing the game that was discovered in March 2025, almost 39 years later. The end result is a method of performing a glitch called **Arbitrary Code Execution (ACE)** that yields a 17-second saving during the final level of the game. For a speedrun as optimised as this, that’s huge.

### Arbitrary Code Execution

Broadly speaking, ACE implies a way to inject custom code into the game, often through regular controller inputs, and then execute it. This can be done by manipulating the game’s memory and *writing* code through a complicated and precise series of movements. Executing the code can have almost any desired effect, including warping the player straight to the credits.

Some players call it the Holy Grail of speedrunning, but for others it’s a curse they’d rather not see on the leaderboards at all. On one hand, more often than not it becomes the fastest way to *complete* the game. On the other hand, the gameplay that players originally fell in love with, the main reason they enjoy replaying the game over and over again, may feel barely recognisable. Thankfully, at the time of writing, the possibilities of its application in Super Mario Bros.: The Lost Levels are still a lot more limited.

For the most impressive display of what ACE can do, look no further than TASBot’s showcase at SGDQ 2022, put together by **[Sauraen](https://www.youtube.com/c/Sauraen)**, @Savestate, **[dwangoAC](https://www.youtube.com/@dwangoAC)**, and countless members of the community:

### Discovery

On March 13, 2025, Twitter user **[LuigiSidekick](https://x.com/LuigiSidekick)** posted a **[clip](https://x.com/LuigiSidekick/status/1900072261555458205)** of Super Mario Bros.: The Lost Levels crashing while playing on Nintendo Switch. It’s worth noting that this person is not involved in the speedrunning scene, and so the clip took a few weeks to be noticed. Quite frankly, it’s a miracle that it was at all. Anybody (me included) not extremely well versed with Super Mario Bros. speedrunning would just disregard it and shrug it off. Games crash all the time for a variety of reasons.

However, some people are built different. On March 28, @Simplistic6502 was the first to replicate the crash with an emulator, research its cause and recognise its potential. On the Super Mario Bros. speedrunning Discord, this gained traction quickly and led to extremely technical and daily discussions about the possibilities: using inputs to skip to the end of a level.

Many members of the community collaborated and iterated quickly after each new discovery. They realised that the only level that makes ACE possible is the final one, 8-4, and quickly went from artificial recreations into proof-of-concept demos and a [tool-assisted speedrun](https://tasvideos.org/6503M) incorporating the glitch. The final frontier was always an RTA-viable setup that is possible to be executed by a human during a full game speedrun.

@threecreepio, @LeKukie and @Niftski were the first to come up with one, and @Niftski was the first to pull it off; not in a full run, but in 8-4 exclusively.

https://www.youtube.com/watch?v=OKovuVj4N0A

### How it works

In this explanation, I won’t go beneath what I truly understand, but there are several levels of complexity, and this is just the tip of the iceberg. Furthermore, it relates to the setup at the time of writing. Over time, the way it is executed is going to change.

Super Mario Bros.: The Lost Levels stores objects in six memory slots. These include things like enemies, but also spawned coins, power-ups, firebars and fireballs. Immediately after those six slots is a two-byte value the game later uses to decide where to jump at the end of the room. Through the introduction of a seventh entity, the player can overwrite that value. In order to even spawn a seventh entity, it’s important that a second controller is also connected, continuously holding down the B and Select buttons. This stops the game from clearing the slots.

It’s relatively easy to cause a crash this way, but through a series of frame-perfect inputs and precisely positioned fireballs, players can write the two bytes which equal the address of the code that shows the credits. When the room ends (in this case through Mario’s death in the lava), the game skips the rest of 8-4 and jumps to the end.

Just today, @Niftski was the first person to successfully pull off ACE in a real run, saving more than 12 seconds over his previous world record.

### Knock-On Effects

In the grand scheme of things, and as far as other ACE discoveries are concerned, this one is a relatively small timesave. However, it is now the fastest way to beat the game using the general definition of speedrunning: reaching the end of the game, usually the credits, as fast as possible and by any means necessary.

These are still early days for the glitch and it’s unclear how much the setup will improve in the weeks and months to come. If it becomes easy enough to learn and execute, it might be adopted by the majority of the community and not much would change. Any% would still remain the main category on the official leaderboards.

However, it’s much more likely that the community will ultimately opt to split the categories. Whether ACE would remains a part of Any% and a new category without ACE is created or if skipping to the credits becomes its own category and banned from Any% will be the result of longer discussions.

Considering other Super Mario Bros. games, it’s unlikely that this particular way of achieving Arbitrary Code Execution and skipping to the end will spread to more of them. It’s hyper-specific to TLL and relies on its memory organisation and level layout. However, given what I’ve already seen and how little I truly understand of the subject matter, I hesitate to make a definite judgement.

For more technical explanations, I highly recommend checking out the **[author notes](https://tasvideos.org/9613S)** for the latest tool-assisted run on TASVideos.org as well as @Niftski 's **[explanation video](https://www.youtube.com/watch?v=ktTxi4_RmjE)** about the setup used and all its frame-perfect tricks.

Mario's Next ACE - The Gold Split - Week #39

Hey there it's AudiblySmiles but call me Mikuze since it's a little easier.

To start we have 3 players entering the Misfit Mascot Relay which starts April 19th, and coincidentally they are going to be playing Twisted Metal 3. The 3 runners are Xencryptous, TheDollMask and myself will be essentially playing against each other for our respective teams as Twisted Metal 3 is not the only game for this event. The players have been grinding away at their PBs(Personal Bests)in the Category Tournament(Minion/Boss Cars) on Twisted Metal(Normal) difficulty. The aim is no clock resets, so good luck to them and myself I guess lmao. I embarrassingly had a crash out due to practice fatigue because of a misunderstanding of the rules, leading to a rule change/clarification. It was around the wording "no resets" as the game has a lives system so technically Game Overing is a reset in normal circumstances but it was meant as no Clock Resetting so if you game over, you can just start at the level you lost on and it's a time loss. It's like trying to drive a car without starting it lmao.

![](https://www.speedrun.com/static/blob/yzrm1xde.gif)

Next on the agenda is Twisted Metal Blacks new activity and a back and forth "rivalry" in the Cheat% Killer Weapons Category. Players InSAMity & you guessed it, AudiblySmiles having been back and forth trading First Place using the fan favorite character Spectre and a new underdog to the category Yellow Jacket. the times are getting so close we are starting to see only several second improvements between the 2, love to see it. Due to InSAMitys hard work they still hold the sweep for Twisted Metal Black Cheat%, so big fat applause all the way around.

![](/static/blob/oeo0r80e.gif)

The entire Twisted Metal Speedrun communities boards have a new member to Management, well not as much new as returning I suppose! NoraMaclean has been hard at work chipping away at reworking every single game in the series boards to make them more modern and accessible. This includes removing redundant categories, updating rules and condensing everything so it's not as overwhelming for new or old players! Additionally due to the new help runs are being verified much faster then before! Average wait time down from 2 weeks to a month alllll the way down to about 3 days or even same day average. Both Nora and myself have been chewing through verifying tons of backlogs and Twitch re-verifications

![](/static/blob/xz0d9q8e.png)

Meanwhile in Twisted Metal 1(1995) Cheat% has once again been swept by...me it's, me again sorry :< Easy, Medium and Hard modes all have been swept with a brand new character to the category, Mr Grimm!!!! Perhaps after his activity there might be even more to come!

![](https://www.speedrun.com/static/blob/3ekd389z.png)

In Twisted Metal 2 land we have a newer player scooping up a ton of Individual Levels(ILs) as fan favorite character Axel. User Najaw11 has recently received 6 World Records so great job! All of the users I mention I will have links to their profiles below if anyone is interested!Old runner VicariousNick has returned to speedrunning once again and is currently in a small back and forth for Twisted Metal 3 as the character Warthog! Nick and player BigSlick have traded World Firsts as the character and perhaps we can see some new optimizations for Standard Cars!

The mod for the unreleased game in the series Twisted Metal Harbor City has also seen a Story mode and Cheat% sweep by...well....y'know...AudiblySmiles. As well as a World Record back and forth involving returning player NoraMaclean! The game, as buggy as it is, has gotten very optimized in it's runs already.

![](/static/blob/5e19lv4z.png)

Additionally more records have been set in both Edgbla Rework Mods for Twisted Metal 2 and Twisted Metal 3! But more importantly the free fan game Twisted Metal 5(V) has seen a full release! It's a game that uses AI as a tool for the art but the game has a small team now working on it to make sure it feels like a genuine experience! Check out the video below if you'd like to try it! I have done a few runs on it and am hoping down the line to have this game have a Speedrun Page as it's actually a lot of fun, feels fresh and no one has optimized it like the older, official games in the series.

# The Gold Split Newsletter - Week #36 - Consoles Can Go Faster, Too?

The Gold Split offers a free, weekly digest of news from the world of speedrunning and beyond.

This **Story of the Week** is all about consoles that might appear to become faster with increasing age. and was featured in this week's issue. The full post includes **more news**, briefly, as well as a fun fact and this week's top times. Check it out **[HERE](https://goldsplit.substack.com/p/week-36)**.

## ![](https://www.speedrun.com/static/blob/wzxxw3qz.png)

# Story of the Week ✨

There are several factors outside of player skill that can make a difference in a speedrun, but that are usually accounted for in order to level the playing field: different emulators, console generations, storage mediums… the list goes on. But usually, console hardware between identical consoles of the same generation is assumed to perform perfectly consistently. This assumption of consistency is necessary in order to make runs comparable.

### Tool-Assisted Woes

In the world of tool-assisted speedruns, **the humble SNES** has troubled the community for a long time. Attempting to play back a tool-assisted speedrun on a real console rather than an emulator would more often than not lead to desynchronisation issues. When inputs are scheduled to happen down to the individual frame, consistency is key.

![A picture of an SNES console](https://substackcdn.com/image/fetch/w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fd99a4d8e-1643-49cf-a348-d828e5e55d75_1200x850.jpeg)*Image credit: JCD1981NL via Wikimedia Commons (CC BY-SA 4.0)*

As reported by [ArsTechnica](https://arstechnica.com/gaming/2025/03/this-small-snes-timing-issue-is-causing-big-speedrun-problems/), [404media](https://www.404media.co/super-nintendo-hardware-is-running-faster-as-it-ages/), and [IGN](https://www.ign.com/articles/speedrunners-left-scratching-their-heads-after-new-discovery-suggests-the-snes-works-faster-as-it-ages), Allan Cecil, better known as **[dwangoAC](https://www.youtube.com/channel/UCkij8hgkomFCsXGAFtv1sgg)**, keeper of TASBot, has recently launched a large-scale investigation into the underlying issues. On [Bluesky](https://bsky.app/profile/tas.bot/post/3lj47u3fga22n), he asked community members with an SNES and a flash cart to run a software test on their console and report the outcome.

More than 100 people responded, and the results were consistent. One specific frequency measurement seems higher on average than it was more than 20 years ago, implying that this part of the console may be becoming faster as it ages.

### Technical Details

The aforementioned articles do a much better job at explaining the technical details, so I’ll keep this short. The SNES uses an audio processing unit (APU) with a digital signal processing rate of 32,000 Hz, at least according to the documentation. This sample rate is set by a ceramic resonator, and these types of resonators are known to be affected by external factors like heat.

Emulator developers had already noticed a trend toward a faster sample rate in the 2000s. In order to compensate and to make the emulator work for all games, the emulated sample rate is set slightly higher than the documented one, at 32,040 Hz.

dwangoAC’s collected test results from the community suggest that it might now be even higher with an average of 32,076 Hz, while heat fluctuations had a much more minor impact than expected.

In practice, a faster sample rate means that audio data is being delivered slightly faster. This often happens during room transitions or between levels. During regular gameplay the game still runs identically, but loading times will be sped up ever so slightly, not noticeable to a human.

### Real-Time Speedrunning

We all want to know: what does this mean for real-time speedrunning on SNES hardware? Well… it’s complicated. The consensus so far seems to be that the difference in loading times between consoles is not big enough to impact RTA speedrunning, and that even on longer runs we’re far away from deviating by even a single second. Secondly, the true impact also depends a lot on the individual game, the audio driver and the interactions between them.

There are however plenty of games played at a very high level on real SNES consoles that measure their leaderboard times down to the millisecond. Hypothetically, if two runners in a longer run like Super Metroid (Any%) or The Legend of Zelda: A Link to the Past (No Major Glitches) finish less than a second apart, could the difference in sample rates be enough to matter? I can’t say.

Ultimately, there is not enough reliable historical data to confirm the trend that the speed of the SNES consoles has increased with time. The only other sources are Nintendo’s documentation and single measurements on a smaller scale. It might very well be that the speed is consistent over time, but varies more widely than expected between consoles. It’s an important reminder that perfect consistency is difficult to achieve.
