Yes, though that can be done without even doing this tutorial. It doesn't make for great game design though. :/
Is this tutorial compatible with JPAN's hacked engine? I can't seem to get any Flight Spots to show up in Advance Map (both 1.9.2 and 1.9.5) to work on a ROM that has the patch applied. They still work in-game but I don't really have a convenient way to move the Flight Spots around.
Nevermind, I just can't follow simple instructions. Great tutorial!
