Attention! Via some methods found on /r/pokemonrng, I have been able to cut down the time needed to get a shiny flawless 6iv Faraway Island Mew from 5 weeks to one day using VBA and Battle videos. My newest post has the save file needed for RNG'ing the mew. Based on this info, for legality testing I created a 3gpkm of a special 6x flawless 31iv Shiny Timid Faraway island mew, with the OT data set to the PokePakku Mew's OT Profile, but with the Secret ID set to 31337. Hopefully this can be legality checked to improve your checkers.
Thanks, and have fun!
I hope that this makes the RNG effort for method 1 work better, and that my discovery of the Japanese nickname exploit allows one to make vanity pokemon. If you want a 10 digit nickname on the pkm above, you must set the OT name to "Hadou", or any 5 character or less name, and then trade it onto an RNG'd RS save with the same OT data for name, gender SID, and TID, and then feel free to nickname it in English with 10 letter names.
