Well, the original map system was just a common event that would pull up the map image whenever called upon. The new version required way too many images at once though, so I made a mini-script for it that does the same function but with an array of sprites. It draws up the basic map from the original, places a highlight over your current room based on map_id, and manually places down each notation after checking a long list of switches. Was simple enough but tedious due to the time it took to do each one manually. Still, the end effect was worth it.
And by all means, haha. I've been dying to hear someone have an "Oh shit!" moment playing through it. XD
