I'll send a PM for the first part. As for the latter question, you'd just be "reverse-engineering" my tree-cut procedure. You can find it tacked on at the beginning of each tree's event data in AdvanceMap 1.92. Note that you'd have to apply it to every tree in the game since you'd be assigning each tree its own flag.
Oh, okay. I'll definitely be using this patch for my hack. By the way, I suggest we talk about all the music-related stuff (should you want to participate) back in gogojjtech's thread. Thanks again!
