I use Battle Engine Melody and some others for my RPG Maker game. ^-^ So far I've been able to overcome all the problems, until I got to the Active Time Battle. It's been great with the orange haired (default) guy as the hero, but the secondary character I changed, and, well... this will show you what I mean...
EDIT: The same thing happens with the monsters. Don't call me a noob... I have only been using this a day. I've tried looking it up anywhere for three hours!

Huzzah! I don't see anything about Enemy Icons, though :C.
Take a closer look at the article and it tells you to define it using < enemy icon x > in the enemy's respective notebox.
Ah, indeed! One more thing. If I were to say, replace an actor with a new character, how would I go about changing the icon then? After that, I'm done. ^-^
If you're still using the RTP, all you have to do is find that character's face in YF's Iconset and get the ID and add that ID to the hash identifying that Actor. You can use Iconview Melody to do this. YF has all of the RTP monsters and Characters in his default iconset that comes with the Melody Demo, so this shouldn't be a problem.
