How do I change the points on the world map where the player's head appears? I already used AdvanceMap to change the route data, but the player's head still appears in the old location.
On this map, Acacia City was made where Rustboro City was. The map data is changed, but the player's head is still where Rustboro City used to be.
Also, how do I change where the "dungeons" are located on the worldmap? For instance, Petalburg Woods is still in its old spot, and I don't know how to change it.
From the Pokedex (Zigzagoon's entry):
The route data seems to work fine in the Pokedex, but the dungeons are wrong. I can't find any guides for this aspect of world map hacking, and I'm at a loss as to where to start.
