I chose Mahogany Town. It remains in the format of Gold and Silver. I could add some more stuff to it, if nessessary. I also used default tiles, because I'm too lazy to make new ones. So it's a little plain.
Oh, and I wasn't sure to put a PokéMart or a Building. I chose a PokéMart, because I wasn't too sure if you were gonna place the Hideout or not.
And I could defidently edit it to fit more into your story. (I'm not too happy about it, I mean, it's kind of boring)
