Tip: You can use Lunar Magic's Overworld Layer 3 Editing system to edit or create your own layer 3 images (castle bricks, fish, rocks) and apply unique effects per level via the Layer 3 Bypass in the main editor.
This one replaces the lives system by a health system. That means, you can only die by hurting if you've got no health regardless on your powerup or you mount Yoshi or not and gathering health with this patch is the same as gathering lives in the original game.

Hey, I was thinking if you could add a "record" effect, where when adding or subtracting by x > 1, the counter displayed "slowly" increments by 1 per certain number of frames to show an animation. Mine uses a seperate RAM (display only) that every 4th frame, the counter updates by 1 until it equals to mario's real HP.
Actually, nevermind, I have idea, I post that to the library.
