I think Peeky Chew was being a bit rash. The only things on that map that he "created" are the desert and ice palettes, and the palettes on the grey cave and that orange tree. The rest is just ripped from HGSS and modified to be big by me. He didn't really have any right to do that.
Anyway, the reason I said that is 'cause the city and whirlpool markers are still clearly my scaled-up ones, just with a few minor changes. Is all. I could help you with those icons, if you fancy.
