Pokemon VC Red/Blue (UE) - Pokemon Bank compatible Mew & shiny Pokemon (8F arbitrary code execution)
1,935This video explains the steps necessary to obtain a Mew in the english versions of Pokemon Red and Blue for the Virtual Console, so that it can be transferred to the Pokemon Bank. It has been discovered that regular Mew obtained, for example, through the Mew glitch, will be labeled as "problematic" and won't be allowed into the Pokemon Bank.
Instead, Mew must have an IDNo. of 22796 and a OT (original trainer) of GF (short for Game Freak), in order to be considered legitimate. Luckily, we can still use arbitrary code execution exploits in Pokemon Red/Blue to give Mew the required information. Arbitrary code execution in these games can be achieved with the glitch item 8F. In addition, we can also abuse 8F to give any Pokemon a certain combination of DVs that would make it shiny once transferred.

Credit to TheZZAZZGlitch for the method to obtain 8F and for the original code to get any item with 8F, credit to Pidgevil2010 for the bootstrap party setup, and credit to SciresM for the Pokemon Bank discoveries (Mew requirements and shiny DVs). Hopefully I got all of them right.

(*1): I forgot to mention in this section of the video that you must be in the exact spot where I am (edge between Celadon City and Route 8, just above the fourth tree from the right). This is completely necessary.
(*2): At 16:25 (just before the third 8F use), I forgot to add that TM18/TM50 must be replaced with TM21. It's reflected in the screen, but not mentioned in the side text, so be careful with that. If you use TM18 or TM50 wrongly instead, simply nothing will happen.
I don't own a 3DS, so I can't test the results achieved by the different methods explained in the video on console or in the Pokemon Bank. However, it's been confirmed by different people that they work as expected:

CAREFUL: When using the Mew method #1, make sure not to save the game between the fourth and fifth 8F use if your name is just one character long. You can still save after the third and last use. However, saving and turning off the game after the fourth use would corrupt your save file due to having an unterminated name. Again, this is only relevant for method #1 if your name is 1 character long.
IMPORTANT: It's been confirmed that the Pokemon bank will NOT accept Mews below level 5, regardless of ID/OT. If you take the path of capturing Mew through 8F, either do it in a route with over level 5 Pokemon, or make sure to level it up to at least level 5.
KEEP IN MIND: When you perform dangerous glitches like 8F and everything that takes obtaining it, there's always a risk. A crash would very rarely destroy your save file but it's a possibility. It's actually much more likely to happen in RBY than in GSC because the former games do not backup save data and spend a lot of time with SRAM opened. Still, a save file corruption will only occur after a crash if another SRAM bank is loaded, which may occur if the game randomly executes code that does it. I can't assure you that your save is 100% safe, only that if you don't make any mistake anywhere save will not be corrupted. But granted, everybody can make mistakes.
PAY SPECIAL ATTENTION: Some people got their save file corrupted due to making a mistake somewhere. The VC Pokemon Red/Blue is more prone to erase your save file upon crashing due to the way it handles invalid opcodes and stops. Consequently, it's actually quite probable that a crash will result in your save becoming corrupted. Most of the reports of corrupted saves where a consequence of an error in the party setup rather than in the item lists, so make sure to pay special attention that your party is exactly like the one shown in the video everytime you use 8F, with the right Pokemon in the right order and with 233 current HP in your Pidgey.
