I actually made this a while ago, so this isn't new, I just decided to share it as progress is made with my game(s) whenever I have the time for game dev stuff.
You might have noticed the game will be going off of a lettered route format rather than simple numbers. This is because some of the routes are connected to one another, sometimes with forked or alternate paths depending on how the game's story flows. A few of them are event locations where something big is happens in the story, or a Rare/Legendary Pokémon is supposed to show up.
(As always, this is for my own project, so please don't use it in yours!)
