How can i make custom bosses? No matter how many times i look over the guides for it, i still can't figure out how. right now i'm working on faceade in level 2(in oracle of seasons). I just ripped the tiles from the rom i have. it's attacks are 1) drop 4 spiders, 2) spit up fireballs that randomly fall on you, and 3)creates a trail of pits that follow you around.
