Is it Possible to Upload an Impossible Level in Super Mario Maker?

[@JoCr2]

Thanks so much for the kind words Ceave! Sorry, saw this late, lol. (Psycrow) Users, note it requires the disc version, but other 1.0 things like vine clips can make it impossible too. Can also use for things like impossible troll levels that make the player think it's their fault, or give yourself a true dev-only route for uploading just a hard level.

[@Black60Dragon]

Vine Clips actually cannot create impossible levels. They're globally patched, but Nintendo only made them frame-perfect inputs now. Incredibly annoying, yes, but possible.

[@filmsbuildsngaming307]

What are vine clips

[@Black60Dragon]

@@filmsbuildsngaming307 in SMB1, you can clip into a wall by trying to climb onto a vine that is directly behind a wall. Prior to version 1.30 you could simply press right to get the clip, but now it's a frame-perfect input to do the same. Not impossible, but not easy either Here's a video showing it. kzbin.info/www/bejne/i3q6op5-rZeUn6s

[@JoCr2]

Well, on a list Jeffie gave me (not used in this video) was "Vine Clip (old method)" and other things like the height of vines that come from invisible blocks. There may be more than one vine clip method, if that's right. Or it could just be a bad example lol

[@Black60Dragon]

@@JoCr2 yeah, I know that, lol. It was my list he gave you. The old method only differs from the new in the fact that it's now frame-perfect. So vine clips were globally patched, but every level with a vine clip is technically possible. Just stupid, haha.

[@wfjhDUI]

7:45 It's possible that the nature of the Mario Maker RNG makes this genuinely impossible. The full cyclic sequence of the RNG may simply not contain a long enough stretch of consecutive normal mushrooms.

[@charlesidiot4534]

You might be correct, but this requires many researches from an emulator.

[@wfjhDUI]

@@J05TI That would make no difference. Regardless of when the code generates the next pseudorandom number, the entire sequence is predetermined.

[@wfjhDUI]

@@J05TI I'm not saying that the game generates the same exact random numbers each time a level is played or that it's iterating through a hardcoded list of numbers. I'm saying that pseudorandom number generators by their very nature emit numbers from a mathematically predetermined cyclic sequence. The seed just determines where in that sequence they start emitting numbers.

[@wfjhDUI]

​@@J05TI When I say the sequence is predetermined, I mean that in an abstract mathematical sense. As an example, suppose we have a very simple PRNG that generates the next number like this: x = (x + 7) mod 10 And suppose we let it be seeded with any number from 0 to 9. It's a mathematical fact that this PRNG will follow this sequence: 0, 7, 4, 1, 8, 5, 2, 9, 6, 3, 0... It doesn't matter when a computer evaluates the rule, the sequence is already predetermined as a consequence of the math involved. The seed will only change where we begin in the sequence. Obviously production-grade PRNGs have _MUCH_ longer sequences and generally produce higher quality random numbers but the basic concept remains the same.

[@wfjhDUI]

​@@J05TI Here's the problem with that: How do you tell a computer to pick a random number from 1-10? The solution is to use mathematical functions that produce sequences which look random but actually aren't, such as the example I gave. So in your example, it's possible that the PRNG being used is emitting numbers from a sequence that simply doesn't contain a long enough stretch of numbers without a 1 and it's genuinely impossible for someone to play through the level without getting a weird mushroom.

[@constancies]

“These levels should be taken down for the sake of no skip 100 Mario challenges”. Well, you kind of just gave us the keys to the mansion before telling us to keep it locked.

[@elli6220]

Thing is, they should've only patched the glitches in new levels and kept them in old ones.

[@thenameipicked]

That's a nightmare from a software development point of view. You have to have multiple ruleset in your game you need to dynamically switch between. And you have to decide if a bug fix is means a new ruleset or not (and whether to fix it in old rulesets)

[@Black60Dragon]

What's more annoying, is that not everything they globally patched was even a glitch. They also globally patched how vines worked which created impossible levels. It's also really annoying playing a level and not knowing about how something is going to work because you don't know which physics version you're playing on. Hopefully they improve this on Mario Maker 2.

[@rashidisw]

Another popular now impossible was the phantom jump trick, Nintendo patch it up so phantom jump are no longer possible to perform, making levels which use the trick that previously perfectly beatable became impossible to finish.

[@aorusaki]

[@fireboltofdeath]

You're aware it's literally impossible (or atleast extremely impractical) to do that on the server side? There's no efficient or good way to validate it on the server. The client is the only good way, it's not like people are going to MITM their console (which probably wouldn't work) The only issue here is they forgot to make the player clear it before uploading an offline saved level. That is a mistake that happens to tons of games.

[@FeepingCreature]

Nonsense, it's perfectly possible to do it on the server side. Simply have the client send you its game seed and sequence of inputs, and run it through a serverside emulator running in a sandbox. That would also easily let you re-validate stages on patches.

[@fireboltofdeath]

@@FeepingCreature What sequence of inputs? The client doesn't have any sequence of inputs until after they verify it on the client. If you did the thing in the video, there'd be no sequences and depending on how nintend handles that it may cause an error on the serverside (bad, bad, bad) or reject it (good, but the same solution would be even better if you just run the test on the client) And once the client actually verifies it, there's no point in verifying it in the server. This is a simple matter of Nintendo forgot to force you to pass the level before uploading offline levels. There zero purpose of verifying on the server once they already verified on the client.

The pseudo random number generator in Mario Maker is deterministic and repeats. Therefore a "lanky shroom" level with sufficiently many shrooms would call the rng function more times than the longest gap between the two values of the function that would output a lanky shroom. So given an arbitrarily large number of shrooms, at least one of them will always be lanky, and it is no longer a statistical phenomenon. Thus, lanky shroom levels can actually be impossible, given enough mushrooms. 🍄

[@thomasmewily4012]

Hi Ceave, I really enjoy this video, and I was thinking of a way to know if level are still beatable in any version of the game. ( With that, player will know if a level is still possible to beat after an update ). Here is the idea, normally, if we press exactly the same inputs of the creator of the level when he share it, we need to be able to clear the level in any version. If we can't beat it, it mean a mechanic/glitch was patched we don't know if the level is beatable anymore ( maybe yes, maybe no ). All Nintendo need to do ( but they need to do it at the very beginning of SMM, it's better, it is to save 2 things when you clear a level for share it : 1) Save the input of the player 2) Save the "random seed". I guess the random of SMM is based on a seed ( I'm not sure, but it is common in a lot of games ). And that it, with that you can know if a level is still beatable, or if the level can't be cleared by using the same inputs & random than the level creator. (Note : we don't dont if the level is still beatable if the inputs doesn't work). - One of your French follower. (me)

[@Alfred-wz4zn]

Or when you update the game you nead to clear all levels that ar about to be uploaded again.

[@thomasmewily4012]

Why not. Or put the level in a "unknow if possible to clear" state, and the level can't be used in 100 mario challenge ( and switching the color of the window level to red/orange ). Someone need to clear it and the level will be consider like an normal level again.

[@BonzaiThePenguin]

That would require them to run full simulations of every level, which is likely too computationally expensive. Another option could have been recording the win percentage of each level before and after an update and detecting if the percentage decreases drastically, although that would unfortunately require players to lose a lot first. I'm actually not convinced that they *don't* do this, since impossible levels used to exist every time they originally fixed those exploits, but don't exist anymore.

[@thomasmewily4012]

Great idea. They can also add a button "Try if the level is possible" ( or something like that ) in the pause menu, and when you press it, you exit the level and your console test if the level is possible ( it will took few mins, expect if it is a very long level that took hours and hours... ). That would be great in the 100 Mario, and if the level is unpossible to beat, you recover each 1up you lose in the level.

[@Silvergrooves42]

The only problem with needing to re-clear it after an update is that there are tons of really, really hard kaizo levels out there where people have put maybe 10+ hours in just to upload it once, and they probably don't want to do it again. I think it would be a cool idea though to maybe save a copy of the inputs on the level creator's device and give them the option to try and reupload it with the exact same inputs

[@Fleble]

[@Darkkurr]

There are fairly a large abundance of levels that are particularly impossible due to Nintendo patching glitches that could be used to exploit through a course. I don’t think they care about this game anymore to fix any flaws.

[@TheGloriousLobsterEmperor]

Well the Wii U is officially fucking dead. So why should they? Nintendo also doesn't patch ultra shortcuts in Mario Kart Wii, or game breaking bugs on the N64 version of Ocarina of Time.

[@DanielLCarrier]

What they should have done is made sure the game was deterministic with anything random using the inputs of the player as a seed, or at least use some seed they can check to make sure it works, and then made it so when you upload a stage, it also uploads the exact inputs you used to beat it and they'd check it locally. Then even if you hack your Wii-U you can't submit impossible levels. Though that still allows levels where you're extremely unlikely to win.

[@awesome3ds]

If they just rerun the inputs locally, there would be no difference in the ghost block levels. The glitch would work just the same since locally the versions are the same, allowing for the same exploits to take place.

[@DanielLCarrier]

If they're using the modern version of the game, you won't be able to sneak past something that only worked because of a patch. The only way they could get unbeatable levels is if something already submitted becomes impossible. And they could flag any level where the original sequence of instructions doesn't beat it anymore and not have those levels on the 100 Mario challenge until someone beats them.

[@awesome3ds]

A simpler and less software-intensive fix would involve the "beatable" status of levels being made. The problem with the outdated system exploit is that you can complete a level while offline marking it possible, then upload it when connected to the internet when it could be impossible. This could by solved by checking to see if the Wii U is connected to the internet before the level can be tested for uploading.

[@DanielLCarrier]

Or just by retesting it after patching. Still, that would only fix this particular exploit. If you can hack your Wii-U you could make it claim any level was beaten.

[@TheShangryLlamas]

all they would have to do is determine which version of the game you beat the level on. if it doesn't match, you can't upload it and have to beat it again.

I think that the likely hood of someone beating the mushroom level is same as the possibility that someone beats Stone Crush tower for ten times in a row while jumping on to Kamek's ugly head with exactly 1 second left .

[@B3Band]

He doesn't ALMOST guarantee a weird mushroom. The game calls on a set order of random numbers. It's NOT truly random. Therefore, if you know the order, and know the largest space between "good" calls, you can guarantee a weird mushroom every time. See pannenkoek2012's video about Super Mario 64 RNG. Same concept fully explained but for a different game.

[@Nakagolas]

What you're talking about is known as a seed. Offline games like super mario 64 use the time that the game is loaded to determine the seed. Some games use a table, and some update only when a specific action is performed (such as pressing play at the start screen). Games like chrono trigger actually just use a table and advance a spot on a table depending on the actions performed. This is the heart on how you can make a Tool Assisted Speedrun, as the RNG would be predictable, but only on the frame level. Unless you can hit say, jump on the 13417th frame when the game is passing them by at 60 frames per second, you cannot actually tell what is going to happen. Humans are not computers, and even TAS programs can have issues because of this. Check the AGDQ TAS block a few years back, they had issues with desyncs a lot. This would not be the case for this game, however, as this game connects online, and using a seed based on the time the game has been running would be extremely unreliable and could cause all sorts of problems. A good example of this is disabling your computer's time sync, setting your clock to some random time, and watching what happens to a lot of your programs. It's extremely likely the seed is based on real-time, and since you cannot go back in time, you basically will never see the same seed twice. The situation I could see this working though would be to hack your system time and play the game offline. So, the concepts are the same on the absolute loosest definition of the word, but effectively are completely different, especially at the frame level. You cannot use this knowledge for anything more or less.

[@7stryder7x23]

There is an impossible level where you have a cube with a key into it and a red coin above it. You have to tap the cube to get this coin. In this level you need ONE key to go on the first locked door but, because of the red coin, you have a second key. Because of this second key you can't go up with a creeper, so you have to go in the door and die. So how could he upload it ? Actually, there was a pipe to create a second area to put there a second red coin. Then, when he play the level to upload it, I don't know why, he had only one key because the level counts the second coin but after, when you play the level, the level believe there is only one red coin, so you have the TWO Keys. So this is a level impossible. I'm sorry if I mare some mistakes, I'm french.

Password system can be easily reverse engineered, but if it's hashed, and then compared, only hashing algorithm and the final hash can be reversed.
