"The player can inject .PKM data into the game (e.g. in the storage box) if the firmware is a compatible version. The player can modify their save file if on a custom firmware (thanks to an exploit such as SoundHax)."
I wouldn't say this belongs here. Save editing and memory editing have been around since Gen I, and this would mean we'd have to mentiom Gameshark codes and the like as well, even if it's possible to make the result closer to a legitimate Mew now due to more knowledge of how to correctly modify the data.
