On the subject of the lavender comment:

The original use of this glitch involved Lavender Town, but the version useable at the earliest point in-game is Cerulean. Wherever the first trainer you "evaded" is is where you should go to trigger your fight.



Does this glich work in the Japanese Green verison? - unsigned comment from Jsmith (talkcontribs)

Yes, I just tested it mysself. This glitch does work with Japanese Red and Green. I haven't tested Japanese Blue, but I assume it works as well since it is so similar to the English Red and Blue.--Rby4ever 08:26, 17 September 2006 (UTC)

Fire Red

Does this glitch work in Fire Red Version for GBA? - unsigned comment from Lukario (talkcontribs)

Probably not. - 振霖T 05:22, 13 November 2005 (CST)

New Mew

I found another trainer that bears Mew. The Swimmer♂ in Misty's Gym makes the glitch possible too.Sonic Pikachu RTP|1#fan 16:27, 11 February 2008 (UTC)

Any proof??? --Theryguy512 22:29, 11 February 2008 (UTC)
Um... No, but it does work. Really!Sonic Pikachu RTP|1#fan 18:48, 13 February 2008 (UTC)
Hmm........--Theryguy512 22:49, 13 February 2008 (UTC)
I don't think it should make much of a difference if it's added or not. But if it works then put it in. Just check a couple of times that it works. TESHIGIGAS 22:50, 13 February 2008 (UTC)
Agreed. --Theryguy512 01:08, 14 February 2008 (UTC)

Another way to get Mew.

Instead of going to Lavender Town afterwards you can also go down to Saffron City and before you enter the gate to go toward Lavender Town you encounter him.--Pmddbzaotil 21:29, 5 July 2008 (UTC)

L. 1-7 Mew

I heard once that lowering the Ditto or Trainer Pokémon's Attack modifier lowers the resulting wild Pokémon's level. Like if you use Growl six times on the Youngster's Slowpoke before beating it, the Mew will be L. 1. Since you can't increase its Attack, it can't get any higher than L. 7. If anyone would care to verify, that would be great. --隼也 18:01, 24 August 2008 (UTC)

Yes, that's true. That was first discovered at a speedrunning forum. IIMarckus 18:51, 24 August 2008 (UTC)

3rd Person

Should this be from a third person? ht14 02:12, 18 September 2008 (UTC)

Yeah. I was thinking that we should clean this page up so it doesn't look like a walkthrough. I mean, of course, it pretty much is... but yes. Remove the yous. TTEchidna 02:15, 18 September 2008 (UTC)
It's pretty hard though, that's all. ht14 02:16, 18 September 2008 (UTC)
We shouldn't be using the command form either. That means, no "Go to" or "Do this". That's the second person just as much as "then you do this"; command form implies second person. So just removing the "yous" doesn't work either. So this needs to be cleaned up even more so that just removing the "yous".Satosuke 16:13, 19 October 2008 (UTC)
I changed it all to "the player", so i think it's fine now Leaf Storm 18:58, 15 November 2008 (UTC)

Two Mew Available and the Swimmer at the Gym

Gym trainers are unchallengeable after their Leader has been defeated. Thus, while you can avoid that swimmer and he has the correct stats on his Pokémon, he can't be challenged for the sake of the Mew Trick. Someone didn't do their research. Satosuke 12:51, 19 October 2008 (UTC)

And that someone was me. The swimmer is involved in the first method, which doesn't need cut, so can be done before Misty. Sorry for the commotion. Satosuke 12:58, 19 October 2008 (UTC)
Did you test it? Or am I still the only one to have done it?SonicPikachuThe No.1fan 18:18, 2 November 2008 (UTC)


How about the English Yellow Version? Has anybody tested that? Yeah, it does, I've just done it. I'll work this into the main article.--Ggled 11:09, 16 February 2009 (UTC)

Glitch not working right!

The glitch isn't working right for me. Here's what I did: 1. Caught an Abra. 2. Saved. This part is what I'm supposed to do. I just explained it badly. 3. walked to the Junior Trainer next to the bridge 4. Opened the menu. 5. Teleported. 6. He saw me, but I ended up in Cerulean City. OK, I'm done with the bad explaining. 7. Fought the Youngster with the Slowpoke. 8. Won. 9. Saved. What I did first: 10. Teleported to Cerulean City. 11. Went to the Nugget Bridge. 12. The menu opened itself! 13. I closed it. 14. Mew didn't appear! I read the article, so I soft resetted. After that, I tried this: 10. Walked to Cerulean City. 11. When I left the Route, the menu appeared! 12. I closed it. 13. Mew didn't appear!

I think the problem was #9, but I'm not sure. Alakazam 2

"I saw your feat from the grass!"

[[:a:File:Feat.jpg|thumb|right|Visual proof that "feat" is indeed the word. This is true not only in Generation I, but its Generation III remakes as well.]] I can't believe people are still insisting that "feat" is a misspelling of "feet". If anyone even bothered to read a dictionary definition, one can tell that feat is most definitely a word, and as such, can deduce that the Jr. Trainer (Camper in FireRed and LeafGreen) was referring to the act of the player character clearing the Nugget Bridge challenge. In fact, given the barriers across the water, it would make absolutely no sense for the Jr. Trainer to claim he saw the player's feet. In conclusion, the line as given in the game is correct as it is, and any attempt to change the correct "feat" to the incorrect "feet", especially if citing a "spelling error", will result in a warning, and potentially a block if things go too far. --Shiningpikablu252 05:40, 9 November 2009 (UTC)

Lol, funny thing is, I understood when I first played Blue. I was 6. Porygon-Z 05:45, 9 November 2009 (UTC)
Well, he was a Jr. Trainer in tall grass, and the normal length grass itself almost touches the bridge. Also, he sees your feet when you walk up to him. From where he was standing, he couldn't see the bridge anyways, but if it was in FR/LG... this is all confusing to me. --NismoX 02:02, 13 October 2010 (UTC)
See feat, as linked above. He is saying that he saw your battle from the grass. --SnorlaxMonster 01:09, 17 October 2010 (UTC)


"Mew glitch" is a bad name, as it infers that the glitch is centered on Mew, when in fact Mew is simply what many people use this glitch to catch. Rather, I suggest a name like Trainer flee glitch. --SnorlaxMonster. Help here 03:08, 12 December 2009 (UTC)

I'm not sure... I think the Trainer flee glitch as you call it isn't considered canon like Mew glitch... as in known throughout the world... ht14 03:32, 12 December 2009 (UTC)
Well, Mew glitch would stay redirect, but I do see the problem with it being commonly known as the Mew glitch. --SnorlaxMonster. Help here 04:42, 12 December 2009 (UTC)
I think I know. The third method AKA Ditto Trick could become its own article as it involves Ditto, while the other 2 are specifically for catching Mew, and can be left as Mew Glitch. --SnorlaxMonster. Help here 10:43, 12 December 2009 (UTC)
Any thoughts? --SnorlaxMonster 10:39, 28 February 2010 (UTC)
I agree, I never liked the term "Mew Glitch" either. It has absolutely nothing to do with Mew, but can be used to obtain any Pokemon. Likewise, the "methods" in the article should go as well, they're just the same ones copy-pasted all over the net by people who have no idea how the glitch actually work. A proper description of the glitch, how to use it, and what you can do with it is what an article should be about, not the same stupid "follow these steps to catch Mew!!!" crap you see everywhere. Ditto doesn't really have anything to do with the glitch either, he's just a handy way of getting the Pokemon you want out of it, so a proper name should be "Wild Pokemon Manipulation Glitch" or something. Adamant 22:10, 10 March 2010 (UTC)

Make the article on Wild Pokémon manipulation glitch and make the mew glitch one explain just the mew method maybe? Although, this article does actually explain about gettting mew. OwnageMuch 02:59, 11 March 2010 (UTC)

It may not be the 'proper' term for it, but everything I have seen refers to it as the Mew glitch.. even when it's used for getting glitch Pokémon. When it comes to unofficial terms, best go with something that most if not all fans use. ▫▪Ťïňắ 03:03, 11 March 2010 (UTC)
Ignore what I said before, this is right^ OwnageMuch 05:22, 11 March 2010 (UTC)
Yes, but Ditto glitch is another common term (this article even uses it). I suggest a split so that the Ditto glitch is Method 3 and Mew glitch methods 1 and 2. I have the same problem with the Celebi egg glitch, which really only describes how to get Celebi, making a note that it can be used in other situations. --SnorlaxMonster 10:25, 11 March 2010 (UTC)
That actually sounds like it'd be a good idea- put Method 3 on its own page titled Ditto glitch (or even just an entire article with Ditto-related glitches, such a glitchy 'mon).. and keep Methods 1 and 2 on this page. Celebi egg trick also really needs a re-write so it's more neutral instead of being like HEERS HOW 2 GET CEREBI!!!... ▫▪Ťïňắ 21:33, 11 March 2010 (UTC)

Level 1 Pokémon

A user decided that this section be removed as it works everywhere. Can someone reword the section (not delete) so that it describes how to do it anywhere. --SnorlaxMonster 10:39, 28 February 2010 (UTC)

A user was not lying. He did not put it on the talk page as Bulbapedia kept crashing. All it needs to say is "the opponents attack stage from the battle before being higher or lower causes the Pokémon found's level to be changes, which the article previously said, then just say a level 1 Pokémon (which can be caught with this glitch) with whatever algorithm will level to 100. I'm pretty sure it already says it in the article anyway. OwnageMuch 04:09, 1 March 2010 (UTC)
Alright, another user will put a section on List of minor glitches about the glitch that occurs with level 1 Pokémon which causes them to level up to 100. --SnorlaxMonster 06:46, 1 March 2010 (UTC)
And a lazy user will thank another user very much. OwnageMuch 02:54, 2 March 2010 (UTC)

Special Stats

I know which special stat number corresponds to which Pokemon. Should I make a section for that in the article?- unsigned comment from Raikami (talkcontribs)

Yes, make a chart for it in the space I left. It's just the Hex addresses in decimal though, so it's not too hard to get. SnorlaxMonster 13:52, 30 June 2010 (UTC)
Okay, I tried making a graph... It wouldn't save it or something. I copied and pasted the graph stuff and saved it to my computer, but...
First problem was that it was inside an unclosed comment tag, which was hiding it and breaking the page. The second problem was that a table needs a |- to signal the start of each row. I've fixed both problems. Werdnae (talk) 21:46, 30 June 2010 (UTC)

Global Terminal Connections

I go to the global terminal sometimes and look up Mew on it. All the Mew I see on the page are level 7. I wonder if the people putting up the Mew are getting them from Blue, Red or Yellow somehow (but I don't see how it's possible.), or that there could be a possible Mew Glitch in Generation IV?

Pokemon List

Most of the fights with the Rival or fights against Gym Leaders won't let any pokemon appear. Same goes for some other event trainer fights, like with the Rocket Grunt in Cerulean City who stole the TM28 (Dig). To fight certain trainers sometimes it is required to fight a "dummy" trainer before them, to be able to reach them by using HM moves (i.e. cut, surf, fly etc.) and/or talk to them to trigger the fight when they face a wall or another character. The Pokemon which appears will always be the same, no matter which "dummy" trainer has been fought beforehand.

Pokemons spawned by the Rival may differ depending on which starter you choose. There are several trainers with which you can make this bug occour, with one being on Route 12 and 2 inside the Rock Tunnel (A Pokemon with Dig or Escape Rope are needed though) and probably some more.

Here is a list of Pokemon which i have gathered so far that appear with help of this bug:

(Pokemon Red, Starter: Bulbasaur)

Route 24:










Cerulean Gym:



Route 6:



Blastoise (fight a random trainer and then talk to the boy)

Shellder (fight a random trainer and then talk to the girl)



Route 11:









Mr. Mime


M.S. Anne:

Booth 1:



Booth 2:


Booth 3:


Booth 4:



Booth 5:


Booth 6:


Booth 7:






Booth 8:



Booth 9:





Vermilion Gym:

(fight a random trainer and then use cut to get into the gym)




MISSINGNO. (Gym Leader)

Route 9:










Route 10:

MISSINGNO. (Girl near the PKMN Center)

Next up are the trainers inside the Rock Tunnel, i will update the list, when i continue fighting the other trainers. I've once already did this with all trainers up to Route 10, 12 and 8 and there were several Mew's and Version Exclusive Pokemons aswell as rare and unique ones. (i.e. Lapras and Blastoise)

Probably this glitch allows to catch all 151 Pokemons in the Red/Blue Version, without having to do any trades with other players, yet to prove this all trainers need to be fought first. OMG 17:28, 16 June 2011 (UTC)

I actually found an image which lists every Trainer in R/B and the Pokémon they give, since you can lose to them on different Pokémon to produce different wild Pokémon. Caution: Ridiculously big image --SnorlaxMonster 02:23, 25 July 2011 (UTC)

I tried this glitch twice( with another trainer, not the same jr. trainer) in red and i got a pinsir. However, when i tried it the 4th time a super nerd fought me, the one to the left of lavender town, who says "you look with pokemon, but how is your chem?" , upon entry to the road. has this occured to anyone else?--User:tinylittlekitty 14:34, 23 Novenber 2011 (UTC)

It's shortened from "chemistry grade", which is a trainer's text. Trainers' text can appear instead of the start menu. OwnageMuch 23:27, 24 November 2011 (UTC)

Yes, i know. But i still needed to battle him. Is there a way of predicting when you would experience this?tinylittlekityy 05:46, 3 December 2011(UTC)

When you reappear on the route which you escaped from the Trainer after getting the ability to use the start menu back, the game loads the last dialogue box in memory (this can be changed by talking to people, reading signs, etc.) If the event data doesn't match/doesn't exist on another Route then it will be different text which partly corresponds somehow to the former text. You might not even get a Pokémon at the end of it. For example, if you used Fly from a Trainer on Route 6, battled a Trainer on Route 11 (the Pokémon you encounter if you get an instant encounter corresponds to the Special stat of their last Pokémon), then decided to talk to the NPC who tells you about pollution and Grimer in Vermillion City when you return to Route 6 the equivalent text happens to be "Who's there? Stop listening in on us!" (one of the Jr. Trainer (M)'s on that Route) or his after battle text "Whisper... whisper..." This results in a 'slow-motion steps' glitch. If you replace this NPC with one of the Town Maps indoors in Vermillion City it results in glitch text and a freeze. An incomplete list of possibilities by glitchuntress can be found here.
IIRC, even having the start menu as the last dialogue box opened might be different text on certain routes, but its often just the same. I can't really remember, but here's a couple of examples to get the 'chemistry grade' text; after doing the Trainer-escape glitch from Route 8 talk to the NPC in Lavender Town who asks if you believe in ghosts as the last dialog box instead of the start menu, or alternatively go to the Lavender Town PokéMart and talk to the shopkeeper before returning to the route. This also spawns a double battle glitch with the Pokémaniac and the same slow motion glitch. --Chickasaurus 15:59, 4 December 2011 (UTC)

New Twist On Ditto Method

I'm new to editing Bulbapedia, so I don't know all the conventions here, but I discovered something myself a few years back regarding the Ditto method of this Mew Glitch. It goes like this:

1. After fleeing from the first trainer go to a PC and press the A button, which should open the PC.
2. Change your current BOX (which saves the game) and then exit the PC and restart your game.
3. The MENU should now open when START is pressed. FLY to INDIGO PLATEAU.
4. Beat the ELITE FOUR. And you must beat them, you can't just lose to LORELEI to save time (I tried).
5. Go find your Ditto and have it transform into whatever Pokemon you want it too, then beat it.
6. Get to the location of the trainer you fled from first and the glitch will end normally.

So the point is: (1) It's possible to access the start menu before you beat another trainer and (2) you can execute this glitch if you have no more "normal" trainers to fight (except for someone to flee from, obviously), so it can be performed over and over to attain whatever the player wants. I just tested this twice on my Blue version and it worked both times, so I assume it would work on Red and Yellow as well. This seems like relevant information to me, so if someone wants to work it into the article that'd be great. Thanks! Mr. Wright 14:36, 8 August 2011 (UTC)

My method

not trying to advertise my video here but this is my method Maresh19 12:58, 3 January 2012 (UTC)

interesting tip

Thought it would be worth mentioning that multiple uses of this glitch caused the snorlax outside of Vermilion to disapear in American Red for me (abused the heck out of the safari zone and strong trainers). Also, maybe a list of which trainers generate what should be made, for example, abusing the Abra and Jr Trainer method after clearing nugget bridge, i encounted a pair of Nidoqueen, a Lapras, a Gengar, and a cubone (i didn't do it for the entire northern section), and of course mew. Also, the Rocker just outside of the Fishing Guru's Brother's house produces a Missingno, while i didn't want my items duplicated, i had a nugget in the slot so i won't say i was displeased. Shadowfox337 13:06, 22 January 2012 (UTC)

This has already been known for a long time ago, and the Change Box/Elite Four trick as mentioned above but just nobody has got around to adding it to the article yet. Trainer-Fly/Escape glitch does cause overworld Pokémon to disappear. The Pokémon depends on the Special stat last loaded into memory, and it's level the opponent's attack stage (1-7), 7=neutral before you return to the route. In R/G/B Trainers IIRC have minimum DVs and 0 stat experience by default, this means that every Pokémon at the same level yields the same Special value, for instance the Youngster's Slowpoke happens to have a Special stat of 21 (corresponding to Mew's index number).
This is also why the Ditto glitch can be used to obtain any Pokémon excluding glitch Pokémon which freeze the game and those which are automatically managed as Trainers (Special 200 and up). You don't necessarily have to beat the Trainers and you can just faint on them to get their Pokémon's Special stats loaded into memory. [[::User:Wwwxxyy|Wwwxxyy]] ([[::User talk:Wwwxxyy|talk]] · [[::Special:Contributions/Wwwxxyy|contribs]]) who used to post on the temporary Glitch City Laboratories forums made a large guide of every Trainer and their associated Special stats. It was first posted on an imageboards a long time ago, but he reposted it back in 2011. It can be found here. --Chickasaurus 13:48, 22 January 2012 (UTC)

Generation 2 Hexadecimal-to-Special Conversions

I understand that, through the Johto Guard Glitch being used in conjunction with the Mew Glitch, you can obtain many Generation II Pokemon within a Generation I game. I am trying to find a trainer that would give me the glitch-equivalent of Celebi, however I do not know what Special rating corresponds with Celebi, or if one even exists that can semi-safely be stored on a Generation I game (meaning it does not destroy the save data or instantly freeze the game) and successfully transferred to Generation II. If you can provide both the corresponding hex/Special value as well as prospective trainers to perform the glitch on, I would be grateful. However, an answer of whether or not it is realistically possible to obtain Celebi through these two glitches would be appreciated as well. I was weighing this against the Celebi Egg Glitch, as I am not as familiar with that one. TapeWillFixIt 21:02, 22 January 2012 (UTC)

Use the Big List on Glitch City Laboratories (when it's up). OwnageMuch 00:06, 24 January 2012 (UTC)

Trading Generation I glitch Pokémon into to a Generation II game hasn't really been investigated yet. Typically it just results in a message that your friend's Pokémon "appears to be abormal", and the direct cause of that message isn't fully understood. I have heard of Paco81 taking advantage of the Pokémon merge glitch to do something like this. I believe he made the donor one Pokémon, and the recipient another Pokémon so that when you take the Pokémon into the Generation II daycare centre, it transforms.
The general idea of the Johto guard glitch is that you first obtain a bad clone (?????) Pokémon, convert it into the 0xFF kind and then use its 'cloaking' abilities to trade your Generation II Pokémon into Generation I as glitch Pokémon, provided they still don't have Generation II exclusive moves and not the other way round, so there is no need for the Mew glitch or any encounter glitches in Generation I in performing the Johto guard glitch, although unfortunately it can be difficult to obtain a bad clone without Pokémon Stadium 2. There is a problem with conversion, which means Generation II Pokémon with index numbers greater than 250 don't turn into the same Generation I Pokémon all of the time.
The table for equivalent Generation II Pokémon is stored this way. Look up the first value, regard it as "01" (Rhydon's Generation I index number) and it corresponds to Rhydon's Generation II index number of 70h (112). The invalid Pokémon (Missingno.'s and post 0xBE [190] glitch Pokémon) up to 250 happen to be generated automatically in Pokédex order starting from #212 Scizor, with Missingno. 0x34 and Ho-Oh as the only exception. For instance, Missingno. 0x32 is Heracross (#214), and Missingno. 0x38 is Sneasel (#215), though this isn't beta data. The problem is that the game seems to stop reading from #251-#255, and the Pokémon you get no longer directly depends on the species anymore (see these three examples). --Chickasaurus 01:10, 25 January 2012 (UTC)
Also, I'd like to note that there are some Pokémon which simply can't be obtained with the Mew glitch, when you use Specials of modulo 200 and above, a Trainer class is returned by the game (index number-200) instead of the equivalent glitch Pokémon. These glitch Pokémon can be obtained with certain Japanese-only select button glitches, like the fossil conversion glitch or the Johto guard glitch itself (except the attainability of index numbers 252-255 in Generation I haven't been confirmed with Johto guard glitch for the reason stated above). I hope this helps. --Chickasaurus 01:15, 25 January 2012 (UTC)
It was a tremendous help. I had been hoping that I was reading the current hexlists wrong when I saw the trainers towards the end, or that the hexlists were out of date. Thanks for information! --TapeWillFixIt 01:33, 25 January 2012 (UTC)

I did the unthinkable

I was messing around with the glitch, doing the method involving the Juggler outside of Lavender and the Youngster that owns a Slowpoke. When the menu opened, just to see what happened, I saved, thinking it would get me to Mew more quickly if I KO'd it. When I closed the menu: nothing. when I restarted it, the menu automatically opened, but nothing happened. I feel that this information's relevant, but don't know where to add it. Jdrawer 22:55, 5 March 2012 (UTC)

Special 248 to 250 and 253

On the page are the Special Stats 1 to 247. 251, 252, 254 and 255 triggers ZZAZZ glitch. But what about 248, 249, 250 and 253? Well i tried 249, and this glitch trainer wanted to fight: As you can see on the video, the trainer sended out 8, and after trying to attack the emulator crashes. I think something about these special stats should be added to the page. LuichoX 22:46, 11 April 2012 (UTC)

Additional POKéMON list

So I recently performed Method #1 multiple times, the second time around I encountered a Nidoqueen. The third time I encountered a Cubone (all L7 by the way). So it seems that it may change based on the trainer you fight, or it changes based on subsequent uses of the glitch. Is there a place to find a comprehensive list? -Ix (talk) 12:25, 17 November 2012 (UTC)

Hi there, the Hex ID of the Pokémon encountered corresponds to the special stat of the last Pokémon that you battled with. Mew corresponds to 21, Nidoqueen to 16 and Cubone to 17. The level is generally 7, however it does correspond to the attack stage (not stat) of the last Pokémon encountered. So, for example, if you used growl in the previous battle, you would encounter a level 6.
For a full table of special stats and their equivalent Hex ID's, refer to the table listed under Ditto glitch. OwnageMuch (talk) 04:41, 19 November 2012 (UTC)

This article in general

I'd like to put forward for consideration the idea of moving this page to "escape glitch" and offering a broader explanation of the workings of the glitch, rather than having an article that's essentially just a tutorial explaining how to get Mew. I would expect that a section on the use to find Mew would be highly notable, however. OwnageMuch (talk) 07:23, 17 July 2013 (UTC)

Conversation window popped up

Something odd happened while I was doing the mew glitch. I was using method 1: Went to route 24, went down and teleported to Cerulean City. Went to Cerulean Gym, defeated the swimmer. I wasn't sure how many Poké Balls I had, so I opened my menu and saw that I only had 1 left. Went to the Poké Mart, bought some Poké Balls and went to the Nugget Bridge. When I walked onto the Nugget Bridge, the menu didn't appear however, but a conversation window that said: "With your ability, you could become a top leader in TEAM ROCKET!" It obviously belonged to the Team Rocket Grunt at the end of the bridge. After I closed it, Mew appeared, but I shut down my Gameboy because I was afraid that the conversation window popping up instead of the menu might cause any damage to my Save File. I remember that after defeating the grunt, I didn't talk to him. So when I restarted, I first talked to the grunt and then saved before walking down towards the Youngster on route 24 again. I repeated the teleporting to Cerulean city and defeating the Swimmer in the Cerulean Gym. Then I remembered that I would have to buy Poké Balls again and to make sure, I opened the menu again to confirm that I only had 1 Poké Ball left. Went to the Poké Mart again, bought Poké Balls, and went to the Nugget Bridge again. The conversation window popped up again, however. I realized that it might have something to do with opening the menu while performing the glitch, so I shut down my game again and when I restarted it, the first thing I did was buy some pokéballs. After doing so I repeated the whole glitch and when I entered the nugget bridge, the menu popped up instead of the conversation window just like it was supposed to. After I closed it, Mew appeared. Conclusion: Don't open your menu in the middle of a glitch. I just thought I'd let you guys know. Hikari The Language Nerd (talk) 14:08, 31 August 2013 (UTC)

The glitch can cause programmed messages from that route to appear instead of the menu, for example "You look good at Pokémon, but how's your chem"(istry grade), or the one you mentioned. It won't affect your save file. I can't remember the exact cause of it, but someone at glitchcity forums should be able to answer it for you if you want a full explanation.

I watched a video about the Mew glitch a little while ago, so I sort of know why the menu appears there and stuff, and my guess is that because I opened the menu after defeating that swimmer, the menu at route 24 had to be replaced by something and that for some reason the game chose that conversation window. I thought it was the perfect opening for a creepy pasta xD "With your ability, you could become a top leader in TEAM ROCKET!"

Wild Mew appeared!

Hikari The Language Nerd (talk) 12:13, 2 September 2013 (UTC)

The cause is actually because the last menu loaded was the PokéMart menu. If you opened the start menu again before returning then you'd get the start menu to open up normally. When the game opens a text box or the start menu, its 'message number' is written to memory address CF13. When you return to the route to finish the Trainer-Fly glitch, the game loads the equivalent message as stored in CF13 for that route, which should be different. The only exception is if the last message/box was the start menu, which should always make the start menu pop up because its message ID is universally 00 regardless of the map. The way this works is also the cause of error codes that are sometimes loaded for invalid message IDs, so say a map only has a certain number of message IDs and the game tries to load an ID+1, then an error code may appear.
In your example, the message for the PokéMart shopkeeper has a text ID of 01. This shares the same ID for the Rocket at the end of Nugget Bridge. --Chickasaurus (talk) 19:31, 3 September 2013 (UTC)

Details on removable object side effect

I couldn't find these details elsewhere, but I'm not really sure where they belong in the article as it is currently organized (it seems wrong to put it all under the Snorlax glitch heading), so I'm leaving them here instead for anyone who cares. I should note that I've only actually gone through the motions to verify the side effect for the Route 25 method. Everything about the Route 8 method is conjecture based on a quick look at the lists for those areas, so someone should make sure it holds up during gameplay.

The article mentions a list of removable objects that gets updated whenever you move between areas. This list is located at memory address D5CE. Its elements are two bytes apiece, and it is always terminated by a special element that begins with "FF". The list is only rewritten up to the first byte of terminal element when it is updated, so the second byte of the terminal element comes from the last area you visited that has at least one more object than the current area. This part of memory persists through a save, but it is zeroed out for a new game.

After a special encounter, the second byte of the terminal element is used as an index into the removable object visibility bit field (located nearby, starting at memory address D5A6). The corresponding bit is set, which makes an object disappear from the world, if it was visible before. Aside: it follows that the code that updates the object list should have a special case to write the second byte of the terminal element when entering an area with a one-time encounter, although I did not verify this.

So, what all does this mean for the two methods for capturing Mew mentioned in the article?

The first method, which has you returning to Route 8, has different outcomes depending on how you get there. If you fly to Fuchsia City right after fighting the youngster, then the TM19 nearby disappears. That's because Route 8 and Fuchsia City both have zero removable objects, which leaves all but the very first byte of the list from Route 25 in memory. Flying to Fuchsia City from other areas has different results. If you walk through Saffron City instead, then the Rocket in front of Copycat's house goes away.

The second method, which has you returning to Route 25 from Cerulean City, has only one outcome. When you first arrive in Cerulean City, there is a policeman guarding the door to a house that has been broken into. If you talk to Bill, this policeman is hidden to let you through the door, and an identical policeman (who had been hidden from the start of the game) shows up one tile to the east. After you fight Mew, this second policeman is hidden once more, leaving no one by the door. This side effect can be avoided entirely by fighting Mew before talking to Bill.

Not battling another Trainer

This page is really bad IMO, in that it focuses too much on one specific way of executing the glitch, when it should be discussing it in general (with the current focus of the article instead being examples).

Anyway, in VC Yellow, I tried the wild encounter blackout method (in Viridian Forest), then returned to Viridian Forest without battling a Trainer in-between. As soon as I returned and the Start menu opened, the Trainer that I was supposed to encounter battled me. This doesn't appear to be currently noted on the article, and the messy state of it makes it difficult for me to work out how to add it. --SnorlaxMonster 10:16, 27 February 2016 (UTC)

SnorlaxMonster, that also occurs if you lose to a Trainer and return without flashing the Start menu. Anyways, I would encourage trying to add it to the Sub-Glitches for now until a discussion about the future state of the article can be brought up. --Super goku (talk) 03:09, 1 March 2016 (UTC)

Alternate method for the Mew glitch

After picking up the VC version for Blue and completing Cerulean Gym, I went after Nugget Bridge and remembered the Trainer Warp glitch, then decided "why not" and went to catch me an Abra and test if I could do it. Upon getting it on the first try, I looked up the method and then wondered how I would do it since I had already cleared Cerulean Gym, and that I wouldn't have access to a "quicker" path until I could get to Saffron City.

On a complete notion of randomness, I went back up to Nugget Bridge and was surprised when no menu opened up. I continued on as normal, walking up and battling a trainer before battling the trainer with the Slowpoke. After defeating that trainer, I warped back with Teleport and once again returned to Nugget Bridge, where the menu opened up as normal. I closed the menu and Mew popped out.

So for those who are wanting to use this glitch to get Mew, know that by doing this method, you can get two Mews before even leaving Cerulean City since the trainer you use to warp can be re-used as many times as you want as long as you don't actually battle them. --Zoen (talk) 19:39, 28 February 2016 (UTC)

I thought that was already known about, since that it how I have done it recently, but you are correct that the article fails to note it in order to provide examples. I might be able to fit it in somewhere, but thank you for mentioning this. --Super goku (talk) 03:16, 1 March 2016 (UTC)

"Trainer-Fly glitch" vs "Long-range Trainer glitch"

They're different names for the same glitch. Why is one declared a subglitch of the other?

Also, there was a reason for the previous layout that started with a specific application and then delved into extensions. The Mew glitch is by far the most common known name and the most common application, and it takes into account the historical aspects of the glitch (a specific application was discovered first, then successive extensions were discovered). In the article's current state (particularly with the suggested rename), the article overwhelms the reader with explanations of pieces of mechanics before they even figure out what the glitch is supposed to do. The order [Summary of effect (to draw the reader in to why the glitch is important)] -> [Method/Steps to perform] -> [Explanation] -> [Extensions] works best. Blueapple128 (talk) 04:11, 20 March 2016 (UTC)

It's been 2 weeks with no reply; if no one posts an objection I will reorganize the article back to its previous layout. Blueapple128 (talk) 02:07, 3 April 2016 (UTC)

Someone's problem

NOTE!: If you do the: Long range trainer glitch, and after you have fly/teleport or other moves used, than go to a trainer and black out in that battle, than go to the area where the longe range trainer is, fight the pokemon you encounter, and than you notice that the longe range trainer you have used, no langer battelbale is, this means that that trainer no longer can be used for the glitch (I dont know WHY this happens) (please feel free to correct what i have written, I am just an 12 jears old boy from the Netherlands and discoverd it by coincidence)

(Originally by ZyxwvuD on the main article. I've just copied it here since it doesn't really belong there like that, but I can't tell if there's a "real" issue in there that needs correcting on the page... If anyone can identify a particular error, please fix it.) Tiddlywinks (talk) 00:01, 2 May 2016 (UTC)

removed object from normal mew glitch

im using method 2, with the jr. trainer at route 24 and the youngster at route 25 using teleport. after capturing mew, the police officer outside the robbed house disappear. however, after defeating the rocket grunt that gives u dig tm, the police officer will return. not sure if this is the object for the "Snorlax skip glitch" but i'm reporting what i observed. hope someone can confirm this too -Pokeant (talk) 03:47, 24 May 2017 (UTC)

Apparent {{delete}} tag?

For some reason this page is in the category Pages to be deleted, but there is no {{delete}} tag in this article. Can someone investigate this? - unsigned comment from Marshtompert (talkcontribs)

It is not; the unneeded redirect "Mew Glitch" is. Nescientist (talk) 17:55, 5 July 2017 (UTC)

Aah. I get it. But it appears in grey and italics.- unsigned comment from Marshtompert (talkcontribs)

Return to "Mew glitch" page.
