Y'know what I find weird? That "Mew is under the Truck" thing was universal for people who played 1st gen no matter where in the world.

I remember a friend telling me about it in 1999, and that week I figured out it was bunk. He had no idea and was really disappointed when I told him lol

@LadBooboo Everyone expects it. It's one of those funny universal things.

@Ace Wing your mum/grandma/older female relative keep sewing supplies in those round cookie tins too? Ive actually come to expect sewing supplies as an adult whenever i see those tins now.

Unlike sewing supplies in cookie tins, this is way too specific. Most likely, the internet is to "blame" for this. Sure, quite a few of us didn't have internet access at the time, but there were always those who did, including people who wrote for gaming magazines and such.

@Aggro Satan it was either Golem or Machamp for me

I remember when I was a kid I told someone that mew was under the truck along with a way to get “super strength” so you can move the truck. But for the life of me I can’t remember where I heard it from. What if a bunch of us just had the same idea and told people that bs lie? Lol

Don't forgot about gaming magazines spreading it and ofc the internet existed already

@LadBooboo It's the same thing for that metal box with sewing stuff in it, or the S we drew

@DannieRay23 I didn't have internet back in 98-99 but I do remember my friends telling me that Mew was under the Truck. I don't remember their names or faces anymore but I still remember somebody around my age telling me that.

I saw that rumor in a gaming magazine here in Brazil,so yeah Mew under the truck was here too.

@DannieRay23 When I played Pokemon Red on my Gameboy Color way back when here in Germany, even I got told the "Mew is under the truck" thing. In German. By a friend at the time.  I didn't have really have access to the internet at the time and my English wasn't that good, yet. Maybe my friend got it from the internet or from someone else who got it from the internet. Dunno.

Game translations werent so prevalent in the 90s, especially in emulation. Growing up in South America I played most my games in English, when I searched for game info on the internet I did so in English. I found about the Truck rumor that way and told my friends about it in Spanish.


Never had a gameboy but i still enjoy seeing how all of this stuff comes together, and inherently falls apart.

GameGlitcher had this game and played it a small amount until I heard about this glitch lol

If you have a 3DS this still works on the virtual console version. You just can't transfer the New.

You can still accomplish this on a rom. I've accomplished the brock thru walls glitch before :D


This is one of the most believably accidentally found glitches. I might even had found it if I had played Gen 1, seeing as I hate trainer battles


I imagine that someone was playing this, came across a trainer they wanted to avoid, and so, spammed the start button, and then flew away, then decided to face a different trainer, then after all that, went back to the route, and blammo, there was Mew. Of course, that's just one theory. Who knows, really, lolz

@MrEvilDucky you mentioning CN reminds me. The one part of testing, you might agree on this, that was the worst is playing a game and knowing there was only 1 real redeemable/quality of it and it was an unintended effect that made those games awesome. I cant speak on what I dealt with, but a good bug in a good game might be something like the clipping 1 inch into the earth Red Dead Redemption 1 glitch with the wagon that shoots you into space.

The worst, as i said before, was seeing something that made the game playable/work, and hoping it never got actually bugged because it didnt cause issues, and watching it get patched and that game die the horrible death on review day because it was just soulless.

@Gungho73 Yeah same I alpha tested games for Cartoon Network mainly in debugging clipping boundaries and people were constantly discovering insane shit by performing specific seemingly unrelated actions and then trial and erroring desired results.

You'd be surprised by the efforts people have to incidentally go through to find glitches. I worked testing for some titles back in the day and there was a pretty popular shooter in which I was trying to find what was causing audio clipping issues. I ended up finding a rubber band rock point that only existed if you jumped between two rocks. It hucked you across the map and allowed you to see a secret live event that the team hadn't even finished patching in the legitimate requirements for. Totally unrelated to what I was looking into and it was amazing. I felt like I had gotten one over on the team, much like those who kept hiding secret dildo's in the Japanese copy of Deus Ex. I couldn't even imagine how uplifted/excited the original discoverer of Mew must've felt.

DannieRay23 it probably was Mew unless the original post explicitly states they were told by someone else of the glitch.

it probably wasnt mew, but probably the guy who first found it told friends about this weird random pokemon appearing when you enter route 8 and eventually they realized that it was related to the trainer they faced after flying away and by trial and error found one that gave Mew.


Truly awesome! It's so satisfying to see how such games actually worked and what tricks they used to save memory. Very nice video!


I remember finding out about this glitch and going absolutely crazy with it. I think I had a nearly filled up pokedex before I even got my 8 badges. Then I combined this with a few other glitches in yellow to face brock with a team of a level 100 venusaur, a gengar, and an exeggutor. I miss the days when games were this broken for those who improvised. No fly or teleport to be found that early in the game, so I had to use escape ropes in mt. moon and viridian forest on two specific trainers who allow this to happen anyway


I really like your Gameboy series with LiveOverflow.<br>Takes me back to my childhood.

I really like your Gameboy series with LiveOverflow.
Takes me back to my childhood.


Fantastic explanation, very informative and educational!


As a programmer, it's really interesting for me to see how the Pokémon games work internally. Good job!


i abused this glitch so hard in the past, i caught every pokemon with it and even did the ditto spec trick to capture then all.

god this brings me back, a game with all its faults yet it's perfect.
even the missingno glitch works on yellow with this glitch

Wait, you mean you can summon missingno on yellow using this glitch?  Huh.


This was such a clear, interesting look at this glitch. Great video!


Been loving this series.  Very clearly explained!


Interesting. Very interesting! I've known about the glitch for as long as I can remember, but never knew WHY it worked. Thank you very much for this thorough explanation. :)


You could also include the encounter level modification through a special stat reduction in the trainer battle.


Just tried it out in an actual Gameboy with Pokémon Blue. It worked, and the save file was fine and dandy! :)

Thanks felow uploader, this was sort of a childhood dream of mine!


The real question is, how the hell did they originally manage to find this exploit back in the day??

@Sergiroth As a dumb kid in 1999 with nothing better to do, I intentionally spammed start to see what I could break, and did manage to recognize I had broken the trainer interaction that this exploit abuses. I encountered a Gyarados next to Fuchsia city, showed my friend, and never thought of it again. /sigh

@Alcaste 1. the video literally explains why that happens. (Function titled initBattleCommon)

2. The same function is called to save memory, it's a programming practice known as DRY, or don't repeat yourself (I'm literally a cyber security university student taking a software engineering class right now, I'd like to think I know how developers think.)

3. The assumptions I'm making are much more likely to be true that assuming a developer has any real motive to tell kids on the internet how to get a mew in a game that was already 6 or 7 years old and two generations of games (gold/silver, ruby/sapphire( had come out between the release of red/blue and the making of that gamefaq post lmao.

4. Lemme put it like this. Do you remember exactly what you did this week, 3 years ago? I'm sure you don't unless you have something like snapchat memories reminding you, which they didn't have in 1996. These developers probably forgot about quite a lot of the specifics of the first generation of pokemon games while they were making the second generation games.

@M4RZ A lot of words just on speculation. What always got me was that the trigger was a trainer battle but the result was a wild encounter.

@Alcaste i can definitely tell you without a shadow of a doubt that the devs never knew this was possible. you would have to know quite a lot about how the game works under the hood, more specifically you have to know exactly what values the assembly level code changes (which literally almost no devs know, if any at all), and know how to apply everything AND also have it not crash in the process

EDIT: another reason to prove that thinking it was a dev that leaked the exploit online is fake is as such. Game developers have an extremely busy profession. I'm 100% sure that the developers for the original pokemon games moved on to something else the instant that they pushed the final version of the first gen games to production. Knowing this, it seems HIGHLY unlikely that the devs would not remember how to do something so specific 6-7 years later, after pokemon became a smash hit, and also telling kids about it on gamefaqs lmao

With game shark, to have mew, the game shark card will put a specific memory code
I think, those people how find exploit like this one,  know this code, and trying to find how they can get the same code, with, for only tool : the game

It can be random, but when u see another glitch, who you have to past through the wall, walk 7000 on one direction then 5000 on another etc

By complete accident, like most glitches. Someone wanted to press START right when they got in the sight range of an up-facing trainer and then left the area (by using Fly, Dig, Teleport, or Escape Rope) and then noticed they couldn't open the menu, that NPCs couldn't be interacted with, that trainers that saw you and didn't move softlocked the game... and then decided to investigate it further.

@Alcaste i knew about the missingno glitch and i didnt even have internet back then. Many of my friends also knew about this

My theory has always been that a dev always knew the glitch existed, and leaked the method online.

@weirdboo Probably noticed a small delay when engaging this trainer, tried to fly away during it to see what happened. That worked, but now the start menue doesn't appear, so he tried to solve it by random method, found the trainer and fought him.<br>Start menue worked again so he wanted to clear route 8 properly now, which is why he flew back and entered route 8...

Forgotten Mohawks same way someone found the Missingno glitch, by fucking around


This was very very well explained, thank you!


Excellent video. Thanks for sharing.<br>One question, how do people found this glitch back in 2011? I don't think a lot of emulator/debugger were available back in those days?

Excellent video. Thanks for sharing.
One question, how do people found this glitch back in 2011? I don't think a lot of emulator/debugger were available back in those days?

Back in *2003 and yes, it was found the same way as the Missingno trick. Just bored people messing around

I think the long range trainer glitch was found with luck. Making it to encounter Mew was probably trail and error


This is really interesting, great video as always. I really enjoy this series. I'm also shocked how fragile these original Pokemon GB games really were!


It would be nice if you'd also include how Howl affects the Pokemons level and the exp underflow to level 100 glitch in this.


This is a great video that clearly and concisely explains a complicated glitch. Subbed! :D


being a cyber security university student, i know a thing or two about assembly. im genuinely surprised how clean this exploit is.
Generally speaking, any time you are doing things in a manner like this, the program just crashes.
but these old pokemon games were pretty simple i guess, simple enough to do awesome stuff like this


You should've covered the Ditto portion of this glitch too. I was able to get a 100% completed Pokedex using it without trading a single time, not even with the in-game trade NPCs. You can even fight Prof. Oak using the Ditto method.


its also really neat how the trainer with the slowpoke isnt the only trainer who can make Mew spawn. One of the trainers in the middle route 7 also spawns one, as well as a trainer in (if i recall) Cerulean Gym. So if y'all want to play the game with 3 Mews easily, there you go.


It was interesting learning that it wasn’t because the trainer was facing down<br>I always thought that was the reason

Fantastic explanation, comprehensive breakdown. Thanks for the video.


I really enjoy this kind of analysis! I was always wondering how all this works


I remember when I was a kid I told someone that mew was under the truck along with a way to get “super strength” so you can move the truck. But for the life of me I can’t remember where I heard it from. What if a bunch of us just had the same idea and told people that bs lie? Lol


I read once that doing this with different long-range trainers would result in different pokemon like Gengar. I did the long-range trainer right next to the Bridge in Cerulean and got a Mew as well; it was level 9.


When I first heard about this, I thought it was fake, because the way it was described made it sound like the menu would just pop up in a random place, when there was nothing that could trigger it. Had I realized it was when you first enter the route, I'd probably have believed it.


I remember seeing a video on this same topic where they manipulate the level of the Pokémon encountered by lowering the opposing Pokémon’s attack stat via growl or any other attack lowering move


I remember when i saw this glitch for the first time. It was magical.


I still have my pokemon yellow with a Mew on it. I got it from someone else. We used the trade glitch so I could have a copy. Mew was the only one I needed to complete my pokedex. I find this video fascinating as it explains how my friend might have obtained mew.


I remember I found a guide on the internet more than 10 years ago that explained how you could fight any pokemon with this method, and it depended on certain stats of the opponent's pokemon. You could use stat modifier attacks, such as growl, to change this at will (albeit with limits) and also change the level in which the 'summoned' pokemon appeard. This meant you could set it to level 0 or -1, and then by fighting a sigle fight you would instantly grow to level 100. I wish I could remember how all of this was done, but I can't find the guide anymore.


I just did this glitch today and wanted to know why it worked. 10/10 great explanation!


I remember being taught this a few years after the game came out. Idk how the hell they found out about it


This is so wonderfully interesting to me. What a great video. Thank you for making this!


Great video, could you do another explaining the similar glitch in the Viridian Forest where you catch a level 1 Nidoking and use a stack underflow to level it to 100?


I did this glitch. It was great getting a Mew and having a full Pokedex of 151.


What amuses me is how the game when a variable in memory is invalid or something like an index goes out of range, it just does a completely unexpected thing instead of crashing

you must understand that this is technology from more than 20 years ago, and a universal understanding about the machines that every programmer must know is: "The computer is very stupid" they way they had to program the code back in the days, was primitive, assembly works by sending simple instructions like add 5 to memory postion xxxx,  there was no space (literally, no memory) for some redundancy or sanity check of the functions being excecuted.

talking about the memory limitation, remeber play2 memory card? 8Mb to save your games!!!  today a 16Mp photo from you smartphone might extrapolate it

Today we'd call that a "sanity check".<br>Gen1 and 2 are not sane. x)

I love videos like this! Please do more of them :)


Awesome glitch, and awesome explanation!
My GOD, people like RPGBrandon on the GameFAQ page piss me off , persistently talking shit about something without researching it or trying it for themselves. I hope he later found out how wrong he was haha

Awesome glitch, and awesome explanation!

The thumbnail just screams:

"Oh, you're approaching me?"
"I can't store an internal variable in the game's memory to manipulate the species and level of Pokémon that appear upon a random encounter that's stored in reserve without getting closer."
"Oho, then come as close as you like"

@Raimar Lunardi That's the joke, people associate "Omae wa mo shindeiru" with Jojo so I turntabled

Is that a Fist of the North Star reference I see?

:B


I had already passed this route in my game, so that map you included showing you every encountered trainer and the Pokemon the glitch can perform was REALLY helpful, dude! Thank you!

One more thing to mention here. With that Pokemon spawn map, as long as you have a Pokemon that can do Self-destruct or Explosion and you're willing to lose a little bit of money (that you can get back with the Missingno duplication glitch) to throw the battle, you can repeat this trick over and over again! You do NOT have to beat the trainer you fight in battle! Losing the battle will make the glitch work too! If you lose the battle, you can repeat it over and over again! I taught Teleport to an Electrode and only used Electrode and Self-destruct to get as many Mews to transfer into the modern games as I wanted.


Finally, after 10 years of  become a software engineer, I understand what happened in this game to get mew :D


you can access mew as early as route 6 if u can catch an abra u can teleport against the bug trainer in the grass left of nugget bridge then do the slokepoke thing then head back to nugget bridge for mew fight, you can do this before beating the 2nd gym(misty) skipping the whole lavander thing getting mew early


i did this glitch with every trainer in the game. never wrote down my findings but it didn't take too long.


Nice explanation and I think this confirms, that the Mew Glitch was just an accident/programming error and not a GameFreak secret. It's really funny that all those little code mishaps led to the only way to acquire Mew :)

Pokemon RBY were held with slightly better duct tape than an N64 Zelda game.

@Kevin Pearson it is still a programming oversight, at least in this case. With more accurate coding they could have stopped the long range trainer triggering after fly, or something else to pretend this unwanted behaviour.

This is the “old way” of getting Mew which pretty much requires you to start a new save file. There’s much better ways to do it now and it won’t be at level 7

It's not the only way yo get Mew, now there are lot of ways to do it

It's not necessarily a programming error it's simply that the amount of memory allowed in a Gameboy game was limited and needed to reuse memory registers and can thus easily cause buffer overflows if known how to utilize it. It was simply just limited programming memory and people were smart to learn about it lol


I thought you would have included an explanation on 'why' the Mew (or other Pokemon) are at Level 7. The "7" is the result of whatever Attack Modifier was in the previous battle. The default is 0 out of -6 or +6 (which is 7). For example; If you used Growl once on the previous fight, the Mew Glitch encounter will be Level 6. If you encounter one at Level 1 and then give it EXP under the next level-up requirement, the experience points cap out, giving you a Level 100 immediately. This means you can get a Level 100 Pokemon before fighting Brock in Pokemon Yellow.


Wow, I wonder how they managed to find this out!


I do like hearing about Pokemon glitches. Just a shame the other species don't get much attention in videos.


The one thing we all aspired to as kids. Getting a Mew....I'm thinking about doing this on an emulator, but I fear it won't have the same Magic as it would have back in the day, when I was a child.


Right I heard you say this isn't intentional but have u tried the dead ends on the map u reference? Cause most times u get Gambler as well as other characters I don't remember facing in the game. Which could all refer to the risky play style this would require. They are all unbeatable o_0 you can't even lose against them it pulls u back.


What I want to find out is what happens if you save or open one of the other menu items.


Few questions I have about this glitch.
1) Does it work on Virtual Console?
2) Will the mew transfer through bank?
3) Can the mew be shiny hunted?


24 in games hours??? Lol I probably spent 24 in game hours getting through that damn cave without flash.

You are a true hero. Flash must be avoided at all costs.


amazing video, another cool glitch to do would be arbitrary code execution with 8F


Incredible explanation!<br>One question, why is it that the encounter is always at Lvl 7?

Incredible explanation!
One question, why is it that the encounter is always at Lvl 7?

The species number is taken from the Special stat of the Pokemon you last battled. The level is taken from Attack stat boosts - specifically, no Attack boosts is 7, 6 Attack drops is level 1 etc. There's another glitch you can do with this - if you use Growl on the last pokemon before mew 6 times and catch it on level 1, it will have -54 EXP. If you then give it less than 54 EXP the Mew will go to level 100 due to underflow.


just thought it would be awesome if people would post videos about just explaining how routines in classic games work, this is pretty close!


Thank you, from your lesson I am learned ghidra. Now I am reversing of GTA2 and making trainer for it, car\ped spawner, mouse support, currently working on strafe support.

Pretty cool. Always wondered if there was a flag to make GTA5 less arcade-y and more like GTA4

https://github.com/izawartka/gta2-trainer-cpp if you or someone else are interested


To get a second mew in red and blue you can do it with the first trainer in misty gym if you haven’t beat that trainer


I'm completely not in Pokemons, though your explanation is fantastic, good work!


Man. seeing all this explanation with the scripts makes me want to play the game again. It’s like playing Skyrim but with mods.


I love that square filter on top of the game, it looks great!


Interesting to see this. I was one of those people reading the GameFAQs video thinking..this is BS but then I tried it in 2007 and was like "HOLY SHIT". I then made a video on it and it's still sitting on my/this channel to this very day 13 years ago.(https://www.youtube.com/watch?v=_K8jtT8kiok)

That said, great break down of this glitch. Very well presented and informative. Very nice!


I'm pretty sure ,that I've once encountered   the young trainer near bill and flew to lavandia and went left. I ignored the old man.


You can actually do this earlier in the game before you even get your second badge. So fly isn't required. You just have to catch an Abra and teleport away from the trainer in the wild grass to the left of the bridge in Celadon.

@stacksmashing You can do a similar thing in Viridan forest on Pokemon yellow, Get poisoned by a wild weedle, Faint on the exact tile you interact with the lvl 9 weedle guy (last trainer outside of the forest), Must have healed your pokemon before hand in Pewter City and when you go back into the forest the start menu wll pop up and when you click it away you get a Nidoking. (Probably not really good explained). Pikasprey had a glitched yellow speedrun of this showing the trick. I am kinda interested if it works the same way as the fly from start menu cause you never opened your start menu to begin with.


I was able to get mew earlier. Use the trainer in the grass to the left of the Nugget bridge to start the glitch. Then use abra teleport to then battle that slowpoke trainer. It still works


This was one of the single most notable glitches of the 2000s


U forgot the Mew's Levle.  The levle of the mew is read from the same registry as the trainers pokemon sats.  If you use growl 6 times to take it from 7 down to 1 the mew will be LVL 1. at this point take youre new  Mew to the first grass and use it in battle so it gets lower than 12 exp or whaterver it needs to levle up, this will break the game and mew will get a random generated number of exp easily take it to 100 if youre not extreamly unlucky with the random number. This is used verry often in glitched speedruns of the game


Damn, imma boot my OG gameboy to try this, I always wanted a Mew.


this glitch is awesome, when i first got my copy of pokemon red, i just wanted a mew on my team and i did it, alas it was like 6 years ago and the battery on my red copy is dead, it was great while it lasted.

If you learn to do a little soldering, you can get it working like new. There are even ways to change the battery without losing the save. Batteries are really cheap. I bought a pack of 6 on amazon for 5 bucks.

Just pop it open and replace the battery


thats so cool! Any plans to cover any of the later games? I imagine the glitches in them are more sophisticated

@stacksmashing cheers! This stuff is so interesting :D

To be honest I’ve never played the later games, so the answer is maybe :)


Add to this that the pokemon you battle in this case the slowpoke's attack stat is 7 and 7 is also the lvl of the mew we encounter.  If you use growl 6 times on the slowpoke we bring the value down to 1 and then we battle mew at lvl 1.  When we get a lvl 1 mew it's lower than the lowest lvl the game is coded for  (2 is the lowest).  if we battle a pokemon at rout 1 and make sure mew does not get enough exp to levle up the game will generate a random exp number with max amount of numbers ( or  something similar) and this will grow mew to Lvl 100 instantly.


By the way, just saying you can manipulate the glitch to get a wide variety of Pokémon. It's pretty much following the glitch but adding a middle step. Teleport/fly/escape from trainer from route. Fight a different trainer in a different route/area. Go fight a wild Pokémon with a specific special stats. Go back to the original route. Close out of menu to get the manipulated encounter of your choice


This is the kind of thing that happens when you try to cram the awesome of Pokemon down into a 16-bit address space. There just aren't enough addresses to go around, so some of them have to pull double duty. That's when you get REALLY fun results.

And now, most devices use 64-bit addressing, which (if my math is correct) is a little less than 300... TRILLION times as much addressable memory 😂


Another way to do this glitch is to use a Channeler in the Pokemon Tower in Lavender Town. Same initial process of pressing start as they appear. Then use Dig or an Escape Rope. When I did it this way, I fought a different trainer after escaping and the encounter was a Magmar. I did this in Yellow version. There is also a Fisherman on the bridge south of Lavender Town that can be used.


Actually that means there's two ways to catch Mew you can do it completely in Misty City. That's how I personally did it.

chandler smith just like how he recreated the truck hoax, I think he did this one with nostalgia in mind for the “original” method


Just wanted to mention for everyone watching this, that this mew can't be transfered to new generations cause of the location check not checking out. Pokebank will not accept this and it might get your Nintendo online blocked if it were to reach the newer generations somehow.


Awesome sir. Subbed and liked. Need to stay with you longer to learn sth more


Idk why I waited so long to watch this video.<br>It's very good.

Idk why I waited so long to watch this video.
It's very good.


There's a method to get Celebi in silver that's still hidden that i did on accident before.


Its actually called the trainer-fly glitch traditionally.


Out of all the videos I’ve seen on this glitch trying to explain it, this is the only one that clicked for me


I've been curious about a function in the Trainer Fly glitch that I've stumbled across a couple of times.

When using the hex code 249 instead of the desired code for Mew, you fight someone who I think may be a version of Blue or P. Oak who uses a team including Missingno., Rhyhorn, Lapras, and another strange glitch pokemon. When I battle this character at the end of the TFG and sequence the deaths of the pokemon properly I end up with the trainer appearing and releasing a series of game related noises for up to half an hour. They mostly cycle between the Rhyhorn growl and the Fly jingle at slightly irregular intervals. I'm fascinated why, I'm assuming I managed to link the trainer's success jingle with the overflow information from performing the glitch and the sound files have started reading from the wrong area like a hex code acid trip.

If anyone else has run across this I'd love to hear about it


Damn, I just got my Gameboy working after more than a decade, and started playing Blue again. I saw this video just after being done with celurean city......... Rip, I'll start over


BTW you can get Mew as soon as you get past Nugget Bridge.  Just need to avoid the trainer in the grass so you can catch Abra.  After you catch Abra, perform the trainer glitch with that trainer you avoided and use Abra's teleport.  Then battle either the Slowpoke trainer OR the Lass in Misty's gym with the Shelder.

Yep, any long range trainer will work :)  The script attached to the video also resets the two trainers you mentioned


Theoretically, if the defending Pokémon raises its attack modifier, would the encounter’s level go up? So if you LRTG a Mew up to level 10, you’d be able to do the shiny Ditto glitch, but this time get a shiny Mew!


When I was a kid in the late 90s, I went to a school that was only up to 4th grade, so we had no contact with smarter older kids that could debunk our lore. Internet was almost non-existent where I lived, only some people had it and it wasn't that much used, so we kids never really thought that answers could be on the internet. The answers came always by "that friend of my friend" Gamesharks and cheat were also unheard of where I lived.

.

One time I met this older kid that had learned the Mew Glitch. But it wasn't considered a glitch, more like an in-game ritual you had to execute to summon the legendary mew. He told me this crazy bullshit story on how to catch it then wrote it on a paper with some diagrams. I never saw him again, we were both spending vacation in a hotel with our parents in a faraway island, and I left earlier than him so I never saw him catch Mew, but he gave me the notes on how to catch it.

.

For the next 3 full days or so, as much as I remember, I was trying to follow the steps of the "ritual" to catch mew. The notes were full of orthographic errors and ambiguous steps, so i couldn't do it first time. I remember being puzzled by the mention of the word "abra" which means "open" in my language, and I only figured out later i needed Abra with teleport (he didn't mention Fly). I had my party ready with the strongest pokemons, that could paralyze, leave HP down to 1 etc.. and a gazillion max potions, revives, ultra balls, prepared for the hardest fight of the game. The kid never told me Mew's initial level, only that he was the most powerful and difficult to catch.

.

On the third day, I did all the steps correctly by chance. When the fight song started where there was no grass in Cerulean Town, my heart started beating really fast, and when Mew was on the screen, I almost couldn't breath. I remember being a little disappointed by Mew's level, but didn't stop me from being excited and feeling special (I was the first one to own Mew in my school).

.

I never shared this secret with anyone at my school, I'd just show up with Mew like a hero. I kept perpetuating the "using Strength on the jetski on the Ferry building" myth. And eventually I was selling Mews to my friends for an inflated price (money, snacks, stickers, favours).

.

I would never had lost that Mew's instructions if I knew how much it would feel nostalgic to look at it again.

Good times!


Is there a reason that the Mew’s level is specifically 7 when you encounter it?

Has something to do with the Pokemon's stat buffs being at +0.  If you use Growl on it from say Bulbasaur or Charmander you can get Mew down to level 1 by Growling either Slowpoke or Shelder 6 times.  Then by having it gain xp from a weak pokemon, you can get it directly to level 100 thanks to another glitch.


FYI - this is much easier to do if you use the trainer in the grass west of the nugget bridge as the "long range trainer". This way you can get Mew anytime after beating the nugget bridge. You can also catch Abra for Teleport instead of using Escape Rope or other abilities that are either later in the game or consumes a TM.

Yup, any long range trainer will work :) That one is definitely the easiest/quickest!


I watched a video the other day by PokeTips and he showed that you can use part of this glitch to battle Professor Oak. Pretty cool!

Gutes Video, hab es direkt nachgedacht 👍🏼


Yes its shockingly easy and only requires you to avoid 1 trainer, then come back to him later, teleport when he sees you, then walk up a little bit

Yes. Ive done this same glitch myself many times. I was shown it by a classmate in 5th grade. Not sure how they came across it though.


I would absolutely love for you and liveoverflow to make a video on trading/battling between a Gameboy and an emulator running on a pc


God damn, if someone had known this back in the day, they would have been a GOD.

We had a kid in school that said he’d give you Mew if you gave him money...


I wish the 13 years old me knew you could catch Mew back in 99 !


I think it was that very gamefaqs post that made me try the glitch back in the day. Imagine how surprised I was when it actually worked. I then used it in a fresh save file to complete the PokeDex lol.


you can do the same exact thing on the route 25
the only difference is that you need to do the start thingy with the trainer on the left side of the nugget bridge
then you do the the same with the younster and fly back to verulean and go back on the nugger crudge which will trigger the start and make a wild battle with mew

Yea as mentioned any long range trainer works :)


I love your videos<br>Do you think that is possible to pass SNES Region lock modifiing the game rom? I have a cartridge that has a SD slot where you can put ROM and then flash them to the cartridge. The only way that I found to overcome region block is to install a CIC chip and I think that may be a way to modify the rom of a game as Earthbound to play it on a PAL console but i can't find anyone that has done/try that.

hey, very interesting video! would u consider making a video about how to patch the call of duty 2 executables to remove the Safedisc check and thus make it playable on windows 10? if not: do u have any tipps on how I could do that myself? like what programs I would need, what to look out for ecc. thx!


First glitch I ever accomplished was the brock thru walls glitch. And I did it on a Gameboy rom on my phone. So if you guys still wanna try these, just get an old gb rom :D


Do you know if you can transfer the new to newer versions of the game if caught on the 3ds virtual console?


You can actually do this glitch as soon as you get to cerulean city anfrer beating the bridge rocket team member, just head to the left and catch an abra (dont fight the trainer in the grass) save and then proceed to walk down directly to the trainer and open the menu and use teleport as soon as he notices you (you have a few frames to do it right) after that go and fight the trainer and then go back walking to the bridge and mew will appear

You're correct, that is what I thought he was going to explain. Hadn't even heard of this method before.


If you fly to cerulean city efter the slowpoke trainer and Then start Walk up the golden nugget bridge the start menue Will pop aswell and Give you mew encounter

So not sure How the route8CurScript impact :p


Damn it took 17 years to find out how to how to catch Mew without a game genie.

Lord Krythic in 2003 there was tons of rumor and misinformation like mew being under the truck. I’d seen someone catch mew through this method, but they often didn’t show the setup or did not explain how to do it properly. Because it was mixed in with many lies, I thought this glitch was fake for many years. It was much harder to get correct info on the internet back then.

Did you not watch the video? He shows that someone discovered this in 2003. Get yourself checked for being on the spectrum.


I would be curious why they left so many MissingNo's in the hex table...


I honestly think, of gamefreak purposefully recreated this method intentionally in the later games to catch or find rarer pokemon it would gain interest and hype very fast.

They need to embrance the fanbase instead of trying to lock-off certain aspects from the game. Whether it's preventing bugs, crashes, references to rumors and jokes, features returning (and staying) from older games people wanted (like following pokemon, battle tower, etc...) or just adding a failsafe pokemon should missingno appears (like the ??? or glitchy sprites).

They need to embrance it, not pretend it never happened. "Let's go" looked so promissing until they scrapped everything in "sword and shield".

I haven't played any of the newer ones, but I agree: If there was a movable truck that gives me Mew in one of the new games I'd love it, or if you could re-do the MissingNo glitch etc...

But yea, I only played Gen 1 unfortunately so far :)


theres another version of this glitch that can be done purely around cerulean in a very similar way but uses different locations for the same result and i was wondering if it works the same way.<br>as i remember it, you initiate the long range trainer glitch on the lass(?) in the grass left of the nugget bridge, but use an abra to teleport back to the pc in cerulean. then, you fight one of the trainers on route 25 (i believe the same one as for this glitch). then teleport to the pokemon center in cerulean again and when you walk up to the beginning of nugget bridge, the menu glitch happens and triggers the mew fight. i could have little details wrong as its been a while, but this was actually the only way i've ever done the glitch and since its able to be done so much earlier in the game it seems weird to me the way in this video would be the popular method.

@stacksmashing i see, thanks for the info

Yep as said it works with any long range trainer! My script also resets that trainer, so both can be tried in the emulator. I just used this trainer because the 'first' instructions were for it :)


I've always wanted to find a channel that involves code and gaming which actually shows and explains the code they use or modify, great job


I really like the shader you're using, what is it and which emulator it is on?

It's SameBoy, with the "Monochrome LCD display" shader


Noticed that there was another place where you could get a Mew, or a Pinsir. Wonder what the difference is..

@David McGill I certainly did not. I remember catching a random missingno but have no idea how I ran into it. Wasn't any crazy way..

I had always known of it using the guy standing in the grass west of the nugget bridge and one of the trainers in the gym.


I don't know what I did, but years ago I did the glitch got the mew, but it had the move transform, and nothing else!!! Always wondered is that weird? Rare hard to get with this glitch? And could anyone explain how it got the move transform?

Mew learns the move transform at level 10 and should always know the move pound. It learns mega punch at lvl20, metronome at lvl 30, and psychic at lvl 40. It can learn all tms and hms. Edit: not sure why it didn’t know pound, as it is mews starting move. It only learns 4 moves through level up so it shouldn’t be able to be caught without pound.


What does the EngagedTrainerCls represent in the first fight? The ID of the trainer or the ID of the slowpoke?

It’s the second byte of the special stat of the slowpoke!


that isnt the only trainer you can  fly away from or the only person you can use to spawn mew, if you catch an abra go to the rout you found your second trainer on and go left at the top of the bridge, there is a long range trainer rite there and you can use the second trainer in mistys gym to spaw a mew. one of the other trainers in here gym will spawn missingno this way and if you do it all rite tou can have 2 mew and use the missingno to dupe infinate rare candies all before the third gym.

Yea as mentioned any long range trainer works :)


finding glitch is one thing u explain it by code like nothing.... u too good at coding man


Isn't there an easier way to do this with a ditto to force stats?

Anothr To yes, but this vid was an explanation for the original method. A lot of people know how to do it but there’s conflicting info on how it works


It's not the Trainer class that determines which Pokemon appears, it is the Special stat value of the last enemy Pokemon, in this case Slowpoke's Special of 21. The value can also be set by wild Pokemon Special stat as long as a Trainer is battled beforehand to reset the Trainer flag.

Yea I also just added a short text about it to the description - could've been more clear on that. A lesson learned for the next video! :)

@stacksmashing I misunderstood then, sorry. Still, I couldn't pick up on the mention of the Special stat. I'll have to re-watch more carefully.

That’s what im saying in the video. The special stat of slowpoke gets copied into a memory that is LATER, as we go back to route 8, interpreted as “trainer class”, which will cause the encounter with Mew.

This is because the code starts a Pokémon encounter if said value is under 200, and if it’s over 200 it will start a trainer encounter.

As we go back to route 8, the engage trainer code will run and that will cause the encounter with Mew.


1:50 the user Ratster boldy says the coding has been examined and there is no trace of Mew


Im at the SS Anne and am yet to find a working missingno via the LTR glitch


I remember a mew/missingo glitch only for blue <br>Remember downloading it on a school computer and printing it

If only we had the Internet when this game was first out 😭

It wouldn't matter regardless because the glitch was only found pretty late in the lifespan of gen1. That is also why it is not patched in yellow.

maltese 84 that is mostly true, but have you ever watched a long ass show just to find out how garbage it gets, after starting great? Like Lost, the 4400, or even the Chilling adventures of Sabrina more recently. The internet is one of the greatest invention in human history, right behind soap and penicillin.


Can someone please tell ne how to change the order of an opponent's party? A possible mew is hiding in the party as a machop, but it is 2nd out of 4 pokemon. How do I make it so that Machop is the last pokemon to defeat? Whirlwind does not work in gen 1.


How could I <b>not</b> catch it? Childhood me would be super mad!

How could I *not* catch it? Childhood me would be super mad!


I've seen a few videos on here. Mew " glitch" above level 100 " glitch" your playing the creators. Etc. The Japanese lavander town one.


Are there other trainers who use slowpoke that this would work with?

It uses the enemy Pokemon's special stat to determine what spawns when you return, you can actually get Ditto to turn into one of your Pokemon with special of 21 to have Mew appear. (Be sure to have an unbattled trainer walk up to you before fighting a Ditto or else this won't work)


Wait that car movement from the start of the video how does that work? I have tried that as a kid by using strengh and there didn't happen anything.

@stacksmashing Ah ic and I thought that I have missed something xD

I made a ROM hack that made it possible! Made a video about it here: https://www.youtube.com/watch?v=dQLp5i8oS3Y


When doing this glitch why if you growl at the slowpoke 6 times the mew will be at lv.1

Ironically, the same thing still exists in Gen2 despite fans figuring out it just takes a few extra checks in the sourcecode to fix it.

It's an underflow glitch and only happens to Pokemon with a parabolic growth rate.  L2 is the lowest level you can encounter normally because the programmers clearly caught this problem in QA testing.

If you split the exp it levels up to 100 because the exp under flows because 3 is the lowest level possible


I didn't understand a thing but still find it fascinating.


So... you can exchange the battle with Youngster Joey with pushing a boulder and having yourself a Special 21 pokémon and then battling Ditto. So you don't lose trainers.

Not sure why but pushing a boulder it makes the same "trigger" as the trainer walking up to you (Boulders count as a NPC being moved), then you can use the Ditto transformed into your "Special 21" pokémon in the place of that "Special 21" Slowpoke from the Youngster.

Yeah. A few extras steps.


I learned what pokemon u have to encounter to find arcanine gengar and a lapras


Does this glitch have any implications for other games

Well, you could have traded Mew to G/S/C as a consequence I guess.


gen1 is literally held together by ductape and bubblegum

"Gen0"(What I like to call the first two japanese games) is basically just held together by the fact that they expected players to only do stuff that was intended. Seriously, that one is the most broken gamerelease of all time. People calling Sonic 06 that ain't know shit.

I'd say it's held together using school gluesticks and hope.

@Mason Farnsworth and even that is giving it too much credit, lol. The amount of errors and broken content in Red/Blue is staggering! They must of had like 0 testing before they rushed it out to capitalize on the US Pokémon craze.


But I still do not understand why mew was added in the first place if it was never intended to be catched or even used.

The special events happened in Japan. They just never got around to doing it across the pond

Mew was intended to be a special thing, only being obtainable at sanctioned Pokémon events.


" pallet town" well you know me with my art pallet.


My personal fav glitch is getting a level 100 nidoking in viridian forest


Would you please make a video to debug artMoney (dot ru) Searcher Editor? I think it have some nasty things inside but im not sure about it (checking with IDA).


Why did they create mew tho if it wasn't meant to be in the game?


please talk about Arbitrary Code Execution in pokemon gen1


I fucked up my girlfriend's yellow version in high-school by doing the glitch wrong and ended up saving. On route 8 the game would run really really slow and couldn't talk to anyone


So would it be possible to just have mew show up in the MissingNo. area?

@LPFan completely misunderstood your comment 🤣🤣

@Corey Scolaro Obviously anything and everything in a game needs a reference. What I meant is that there is no value in the context of the glitch that matches mew's.

@LPFan mew definitely has an ingame index value (hex) Any gameshark cheat to make him appear utilizes that value.

I don't know for sure that the old man glitch can make a mew appear but I did find this , https://youtu.be/Bt_YeoOjf-o there are many other glitch methods to getting mew either way, and all of them exploit his index value I'm pretty sure

@Corey Scolaro I thought there was no value matching mew tho.

Yeah but it’s more fun to catch the fossil pokemon as fossils

Yes. The wild pokemon data on  'missingno' strip off cinnabar comes directly from you're trainer name. So if you look up values and make your name have a value matching mew,  he will pop up there during the missingno glitch


as good as ever, but sadly as late as ever(except wcry part2)


I didnt hear about this mew glitch til around 2004

I just found out about this glitch right now. I wish I had my red copy with 150 pokemon still. :(


thats cool and all, but a level 61 charmander?


Am I the only one who hates all the random battles?


You can catch mew without ever leaving Cerulean City, all you have to do is walk over to the left side and catch an abra, then you can use that guy that's in the grass to use the long range trainer glitch.

@stacksmashing My bad didn't see it, still cool video.

This is also explained in the description, however wanted to show the “first” way it was done - any long range trainer will work :)


Ur next video should explain the glitch of a Marill changing genders when it evolves

I thought that was less of a glitch and more of them just not doublechecking which values they put in.


No wonder people have been sending Shawn Pokemon roms ,

Please do a normie civilian like me a favor,  show the world and online that there are good feds,
I've seen so many bad feds,  but I know deep down there are good ones,

Or at least people who can see through the live action role play,

If we have the capacity to see through your larp , tell us what the shot is.

I know they weed out people who second guess things,  but,
People won't second guess things if they know what the shot is .

The most I've gotten from someone is, "yes, this is all fake, acting,  larping, whatever , just don't go full 'Quinn Michaels timephone hack' on us" which is clearly a generic answer and doesn't tell me what the shot is.

Sometimes , these people judge a person by their online activity they are monitoring, and get it WRONG , but they never just talk to the person ,  which could easily dispel a TON of their false positives.

Sorry this is kind of off topic,  maybe isn't for some people Reddit space  ,

Like if they don't want anyone to talk about the LARP stuff...
Tell me what the shot is, then I'll know what I can and can't talk about.


all this is great but why is that charmander level 61 let that boy grow


lol 24 in game hours with a pokemon in the day care? <br>Tell that to the Arcanine I left in there for 3 years because I couldn't afford to get it out

lol 24 in game hours with a pokemon in the day care?
Tell that to the Arcanine I left in there for 3 years because I couldn't afford to get it out


I’m pretty sure it is dependent on the stats of the slowpoke. If you use a stat altering move to change the right stat, you can change the level. There is a way to encounter a lvl 100 nidoking in viridian forest with this glitch. I’m sure someone has taken the time to figure out how to manipulate it.

I would like to know, too. As it turns out, if you watch the video, the slowpoke he encounters in the trainer battle is level 17. Might have something to do with it.


So if i want to catch all pokemon with this trick, i need 2 trainers for every pokemon? One to start the glitch and thee second to fight against?

You can use this guy every time since you never actually fight him.


I wonder... who the fuck discovered this.


Nice shaders. Glad its no hqx2/3/4 bullshit


Pokemon but everyone is Social Distancing


But what if i dont have a sav file cuz im playing on virtualconsole on wii i have a different file


Imagine being a game dev in Japan and you learn your slipshod work from 24 years ago is being dunked on by people thousands of miles away :D

A game dev in Japan would think about it in kilometers


My non existing brain just exploded from the words i dont know and the things i dont undertstand jesus all those info


Messing around with the game out of boredom. I stumbled on this by spamming start as a kid in 1999, ended up encountering a Gyarados on land, thought. "huh.. odd" and never thought about it again until youtube was a thing.


Is it still possible to trade Pokemon from the old gbc games over to gba and then over to Nintendo DS

It should be. It takes third party-stuff tho because there is no built-in transferfunction.


I remember when money was black and white. And didn't have any numbers other than what it was.


1:32 - Why are you using incognito mode? It's not like you're looking up porn or anything, lol.

I have to admit, I don't like the filter you put over the GameBoy footage.

That’s fair! I asked a couple of people and with Filter won, but I can see how some don’t like it!


Oh you have a clear gameboy...  Hmmm..... But why is the " boards" green?

Green is an ultra common circuit board color for consumer electronics. Not really a deliberate choice by Nintendo.


I know. Their playing monopoly. All 6 colors.

The missing no. Based on the movie. People find chickoritas totodiles cyndaquils


I don't know what this engaged trainer class business is.  The code calls the Pokemon ID from the Special stat of the last encountered Pokemon, and the level from its attack stat modifier.

That’s exactly what’s said in the video - the slowpoke stat is two bytes long, the second byte is, when going back to route 8, used as “engaged trainer class” . Basically when you go back to route 8 the game tries to engage the “trainer” that should be stored in engaged trainer class.

But, that trainer class was overwritten by slowpoke.

So the game basically (back on route 8) tries to start a fight with the trainer class that came from slowpoke’s special stat.

As the value is under 200, the game decides it’s a fight against a Pokémon, and the Pokémon ID comes from that byte that is both engaged trainer class AND special stat - depending on where you are in the code.


is that the new trend rn? warming up glitch videos of 20 yrs old games who are already plenty available of? Also everyone knows that already thats basic knowledge

Found it interesting and I couldn't find a video that gets all the details right - if you find a great one let me know!


You got a part of it wrong. The reason that it got mew is because of the SPECIAL of the slowpoke. The special stats value determine which Pokémon you get. Hell, you could change a trainer pokemons(and their lvl/stats) and you will see a different Pokémon. Why? Because special stats.

Trainer class has NOTHING to do with the glitch. You could do the « Trainer fly glitch »(as it known in the glitch community) with a different long trainer(below saffron city) AND a trainer that have a Pokémon with the same special value of mew(other than the youngster with the slowpoke) and it will give you a mew as well.

In the video I'm explaining that the special stat of the pokemon is copied into the memory that is also used as "EngagedTrainerClass", which is the reason the glitch works in the first place. It doesn't have to do with the trainer class of the youngster, but as we go back to route 8 the trainer engagement will load the value in engaged trainer class (which was set by the special of slowpoke).
