Lol If I can find some of my old Roms I'll show the maps to you.
And whenever I started rom hacking I was really lazy and created a hack that was an obvious edit of ruby. You started in an underwater town for no logical reason, and then when you left the town you appeared in the abandoned boat which was overrun by team aqua grunts with advance text edited text. Until you found a bag that still had mudkip, torchic, and treeko, and then you warped to professor birchs lab disguised as a cave, and that's pretty much were it stopped. XD
