For anybody that wants to work on this game, I made a helper lua script some time ago. I have not made any attempts to update it for recent BizHawk changes, but it's simple enough that it should still be compatible. It was originally intended to show hitboxes, but the hitboxes are determined by unique subroutines per enemy, thus being a pain in the ass. It still displays HP and damage values of attacks, which should be pretty helpful. It also does some strange calculations against a semicircle around your character, which I can only imagine is your shield.
