"Step by step guide on how to obtain a Pokebank-compatible Mew in Red/Blue UE, with working 8F ACE setup"

u/TransgenderPride had the idea first, so credit where credit is due. His original post is here: http://ift.tt/2kxKWfC, there were some issues in the proposed 8F code. So I rewrote it, also using bag items to spell out the code, and tried my best to optimize the whole thing.STEP 0: The goalRegular Mew cannot be transferred from RBY to the Pokemon Bank. Instead, its ID Number must be 22796, and its OT name must be "GF". This means that a Mew obtained through the Mew glitch (also known as Trainer-Fly glitch or Trainer Escape glitch) won't be directly compatible to be sent to Gen 7. We're going to use arbitrary code execution with Red/Blue glitch item 8F to turn our Mew into a "legitimate" Mew.STEP 1: Obtain MewGet a Mew, through the Mew glitch. I assume that nearly everyone with Pokemon Red or Blue in the VC knows how it works, but otherwise, here's a video: https://www.youtube.com/watch?v=E757YbGVWooDeposit the caught Mew in the first position of Box 1 in the PC.STEP 2: Obtain 8FVideo-tutorial by TheZZAZZGlitch: https://www.youtube.com/watch?v=98_azamLeh4Easiest method to obtain 8F known to date, and I don't think it'll be beaten any time soon.STEP 3: BootstrapingThis step is meant to redirect program execution to the third bag item, upon using 8F. Requires the following party setup:Exactly 5 Pokémon in the partyPidgey as the first PokémonParasect as the second PokémonOnix as the third PokémonTentacool as the fourth PokémonKangaskhan as the fifth PokémonFirst Pokémon's current HP has to be exactly 233Credit to Pidgevil2010 for this setup.STEP 4: 8F code to execute / item listI've tried my best to make the item list setup as accessible as possible, and in the end I thought that the best way to accomplish it was to separate the process in different 8F uses, one for each byte that needs to be written.Item list corresponding to each 8F use: http://ift.tt/2kxNkis five different item setups are required in total, the item lists are very similar.To obtain more than 99 of a given item, item duplication with MissingNo. or 'M must be used, so the Old Man glitch is required (there are other methods to trigger a MissingNo. encounter, but this is probably the easiest). Remember that encountering MissingNo. or 'M increases the quantity of your sixth by 128, provided it is lower than 128. Be careful with this, as you won't want to alter the quantity of items that can't be tossed.It should be added that there is always the possibility of just changing your ID number and player name if you want to send more than a single Mew. This way, all the Mew you obtain can be directly transferred. It would require a different 8F setup though.BONUS: Shiny Mew!If you're willing to work a little harder, you can also modify your Mew's DVs so that it becomes shiny when transferred. Two additional 8F uses are needed: http://ift.tt/2kxKzln may also swap the position of your Mew in the PC at this point with any other Pokemon, and have that other Pokemon get "shiny DVs" instead (or do the trick for multiple Pokemon).Final resultAfter doing everything, your Mew in Box 1 should look something like this: http://ift.tt/2kxKoTd that the DVs were changed to match shininess, and as a consequence the Max HP stat changed, resulting on a corrupted HP bar. If that happens, withdraw Mew and heal it in a Pokemon Center, then store it back in Box 1.VERY IMPORTANTIt still has not been confirmed whether an OT name of "GF#" (where # is the string terminator) is enough to ensure that Mew can be transferred. OT names in RBY are 11 bytes long, so the last 8 bytes of "GF#abcdefgh" and "GF#########" are different, even though the game displays them in the same way. This guide only covers changing the first three bytes, and although I'm nearly 100% sure that it will be enough, I can't guarantee it. EDIT: Some people have confirmed it works in the comments, so it should be fine. via /r/pokemon http://ift.tt/2kv0qkT
