There is a rather interesting glitch out there in the original Advance Wars that will allow you to edit any War Room or Campaign map. However, when you do actually get to the editing part, you'll discover the interface is... less than friendly.
It acts like you're trying to battle and design a map at the same time. That's messed up enough. Watch as I mysteriously clear Point Stormy and screw up a campaign mission.
Yes, the sound starts to lag at one point, but that is Windows Movie Maker's fault.
