Maps and genaral ideas involing them

[stormfront]

before I get to the point of this thread I just want to say I know nothing about programming games so my logic may be flawed

Now i have seen a lot of comments all over the forum about how thing x or thing y should show on the map or that we should be able to draw on our maps,,

now on the subject of drawing on the maps I figure has anyone considered the idea of getting a LoZ: spirit tracks rom

ripping out said map doodling code and altering it to work as a mod for DS

(now I figure its not quite a take this and cram it there type of thing but I bet something could be Frankensteined using it at least as a base)

side subject how useful would it actually be?
