Sorry about how long it took. If anyone still needs a second save for anything then here it is.

sav.dat

151 - MEW - E4BE.pk1

Is the mew pk1 file you attached comming from your sav.dat? I'm asking because the one in the sav.dat is a little different, more precisely OT name:

Your sav.dat: 86 85 00 00 00 00 00 50 89 80 82
RupeeClock's: 86 85 50 00 00 00 00 50 89 80 82
scottishdanstfu*: 86 85 50 00 00 00 00 50 89 80 82

*scottishdanstfu kindly shared his savegame with me to check the mew, it's 100% the same as RupeeClock's

@HMM, did you directly dump your savegame with the new entrypoint (soundhax) or did you trade it to your already homebrew enabled 3DS?
I'm gonna see if boxing RupeeClocks's Mew produces this result, I'm kinda puzzled right now.

EDIT: Nevermind, I tested RupeeClock's savegame and boxed the mew: it converted to 86 85 00 00 00 00 00 50 89 80 82 (same as HMM's) so it was really due to boxing.

I guess there's no doubt now about them being all the same (we were pretty much sure anyways).

[RupeeClock]

Huh, I don't think the homebrew method of dumping the save game should make a difference, all will ultimately run a program that decrypts a save file and dumps the contents to the SD card.

Also with thanks to soundhax my cousin might be able to share his save if he finds any time to even play his 3DS.

[suloku]

I went and boxed your mew on my 3DS, got the same as HMM's, so that settles it (I didn't know this happened, I should check how trash bytes are handled in the different games and generations, best case scenario would be that some stadium game erases them completely...).

We have 3 different saves and all 3 mews are the same, alongside the fact that they used savestates (and with it, they were distributing cloned Mews), but still I'm sure someone would appreaciate a 100% confirmation of different distro consoles providing the very same Mew.

Now, when is that pokebank update coming?

 

ps: RupeeClock, I was refering not to the dump method itself, but if he had done another trade before dumping the savegame, as I was thinking that maybe trading again was what changed the trash bytes.

[Guest]

That's weird, so technically the OT changes from "GF" to "GF     " when it gets boxed? 50 is terminator byte isn't it

[RupeeClock]

I guess that pretty much confirms it then, all VC RBY Mews distributed are the same, although trash bytes may change if boxed.

All that's left is to wait for the Pokémon Bank update, how exciting.

Yes, makes no difference visually. I'll test what happens when unboxing tonight.

[Guest]

It may make a difference once transferred to Sun/Moon since OT names seem to be aligned to the right in Summary screen there.

That is, unless the transfer corrects it and removes (hides) trailing 00s on any Pokémon.

 

Thinking about it, it's unlikely that the Pokémon Bank transfer will let you transfer away Party Pokémon, only boxed ones. Therefore the only Mews that will make it to Gen. 7 are those with that first terminator byte zeroed out.

[suloku]

Unboxing keeps it as "86 85 00 00 00 00 00 50 89 80 82". Now I'm wondering if trading over VC will make that 0x50 appear again.

I have a friend's 3DS, so I might as well go ahead and try it.

EDIT: I made some trades between english red and yellow and the terminator from the distribution is gone for good, so misteries... I guess we could find the answer at pokémon red disassemby: https://github.com/pret/pokered

[RupeeClock]

Pokémon Bank update finally dropped!

I got to import my Mew from VC Pokémon Yellow, this required boxing the Mew into the first box.

Upon transferring, it arrived with 31/27/31/31/31/31 IVs and a Timid nature. This is pretty great, as apparently Pokémon imported from Gen I are "guaranteed to have 3 perfect IVs, and a random nature". The Mew already have a perfect spread of 15/15/15/15/15 DVs though, so I'm wondering how they picked an attack IV of 27 when it's attack DV would've been 15.

I extracted my Mew using PKHex if you wanna examine the bytes.

I thought it pretty interesting that it has a generated shiny value too, and a trainer shiny value based on the OT. The GF Mew had a TSV of 1424, I'm interested to see if this is consistent. It might not be shiny locked as a result of this.

Oh yeah and it was also nice that the Bank update gave away free Mewnium Z to Sun/Moon game cards, via mystery gift.

A few other Gen I Pokémon I imported have a TSV of 2512. They also indeed have 3 perfect IVs and random natures, my Rattata got its HA Hustle, my Sandshrew got its HA Sand Rush, my Caterpie got its HA Run Away, and my Mankey got its HA Defiant.

Edit: Turns out SciresM is really on the ball with figuring out how the transfers work, nature is determined by EXP, IVs are purely random, nearly everything always gets its hidden ability, genders are completely random despite how gen II determined them using DVs. Every untrained Mew imported will always be timid, and you can manipulate which nature it will get by getting a specific EXP number.

Ah, good to know that the Mews originally come with 15/15/15/15/15/15 in RBY... that confirms that legitimate shiny Mews can't exist. (As was the case with the original gen 1 Mew distributions, back in the day.)

Well, I can still think of 2 methods to get a shiny Mew, legit. Both in gen 3.

1: Use that glitch to get any Pokemon as an egg and do Mew. Then, use my favorite tool of all time. Triggers PC to scan all the eggs for a shiny match with one of your saves. 

2: Just use a Japanese save and the Mystery Gift Tool to get a working ticket. Then just go do the run-away method to shiny hunt for a Mew.

The only shiny Mews that can happen, are the legit VC ones that are distributed, with their IVs changed, via glitch or arbitrary code execution glitches, or hacks.

So considering PokeTransporter checks for Mews with the OT ゲーフリ or GF and the TID 22796, then any other English VC Mews would have to be identical to the UK one. At least that makes it easy for people to make their own VC Mew saves (which I did just now).

EDIT: Looking through the topic and seeing they used a special version of the game with Restore Points, it might be able to be replicated in the normal games (patch in the Restore Points and the GF option on the Name Select, then play normally until getting the Pokedex, then inject or trade for the Mew and make a restore point in front of the Cable Club). Since the Mews are identical anyway, it'd have the same effect.

Question came up, whether the terminators were checked as well..
I'm going to check soon.

Edit:
Right now, it appears the terminators aren't really checked.
I've had a few different ones, unnicknamed, retyped the OT, and it passed. odd.

Mew's nickname is completely not checked,
OT without the terminators still pass.

So you can literally gen one that easily, that's hilarious. Now is it possible to mod Restore Points into a Gen 1 CIA so we can send infinite Mews like they did at the Japan and UK events?

Well, I would think if you use the old VC injections, you'll get the Restore Point Function.
Now, just inject rom, and let the title ID be the same as one of the official ones, and I'll imagine it'll work.

However, I'm not sure the old VC injections allow the trading patches they worked into the present VC model RBYG uses.

Well, there's only one way to find out! I'll try it later (if someone doesn't beat me to it), I need to get some sleep.

[theSLAYER]

Just for lols, I previously switched out Pokemon Yellow's rom with Debug Yellow ASM rom,
and I'm now documenting how A Certain Mythical Mew got across through the deep recesses of time and space.

Spoiler

I've changed my TID and OT (TID can't be seen here, tho)

Debug Item

This calls Mew as wild battle when menu is totally closed.


Changes it's level to 50


In Battle


Captured


Swapped out game still recognized (cause using same Title ID as original)

See, it's accepted

 

[RupeeClock]

What's most hilarious is that Poké Transporter is accepting a modified Pokémon Yellow as a save source.

It logically follows that it just checks for a matching title ID, and looks at the save contents matching that title, but still hilarious.

Of course I reckon it's probably just easier to clone/inject as many Mews as you please, like if you want Gen 1 TM moves of varying natures.

Moves like Softboiled and Whirlwind are probably the most interesting as Mew lacks access to Recover or Roar, or similar moves. Actually I think this might be the only way to get that legal Softboiled Mew that the Smogon sets use.

I find it hilarious too.
Yup, it just checks Title ID, and Save isn't corrupt, then proceeds to read save.

Also, they didn't bother to language lock, too,
Since Japanese 3DS shouldn't have English Pokemon, if I'm not mistaken.

Yeah, it'll be fun to clone a bunch of Mews, get access to unique movesets and all.
I purchased my Pokemon Bank subscription right before it came online

[RupeeClock]

Yup, I'll definitely be making the effort to get my own Softboiled Mew after this, despite actually having already transferred my Mew.

That's what JKSM is for though!

[HaxAras]

You can just get a gen 3 softboiled Mew. I found this list online of supposedly all the gen 1 transfer moves. I wish it was of more use to me but I don't really know which moves are good or worth transferring.

Yeah, well the images was more of proof of concept that if your TID and OT matches, glitch mew will transfer.
Except I didn't feel like doing the entire glitch

[suloku]

Wait, so they added the OT extra bytes for nothing? They don't check the full string? Does this apply to the JAP mew too?
They really messed up, even the Gen 1 original events had those extra bytes in OT to prevent nicknaming.

That means that IF the transporter shiny DV spread is possible (that damn GB RNG...), it would technically be possible to get a shiny mew via the glitch that can be transported. Of course, it would still be from the glitch, so not really legit but...

ps: I'm pretty sure HaxAras was referring that the only shiny legit mew is the JAP one from Emerald's Old Sea Map event.

Yup, for both the Japanese and English event they don't check the full string.

It seems like it's just there to prevent nicknaming, but doesn't stop Mew from going through Bank.

Nickname was totally ignored, IVs ignored, only OT (without terms) and TID was checked.
