That moveset update looks interesting. Does it also update what level everything is learned at to be close as possible? I wonder how liberties were taken (such as relearner moves, making up for nonexisting moves, etc.)
I'd put the idea into Fire Red or Emerald, but there are bases nowadays that make most of the whole deal possible already with new moves. (which is one reason why I decided to aim for events of the generation the game took place in instead, no one delves into there much outside of Wish Blissey.
