Well, this is Azure Town, the 2nd or 3rd town in my hack and the town of the first Gym.
It's a map from hacking Emerald, as you can see by the graphics.
Well, the tall building is the lighthouse, which is required for beating the game(You get the HM Rock Smash at the top). The beach house is just a fish restaurant, with people(mostly sailors and fishermen) who sometimes give you items when you talk to them(One of which is the Old Rod). The houses are just random houses with generic people in them, some give you advice or items. The gym's type is electric, so that's something fresh from Nintendo's obsession of making the first gym Rock-type. This is my very first map, so it has its bugs in it...
