Working on a lua script, for displaying some useful info, like where hit boxes are.
Green means the hitbox is okay to hit.
Yellow means you should proceed through that hitbox with caution.
Red means you end up dead by hitting it.
The top number, if displayed, means HPs for that Hit box.
The bottom number, if displayed, is a timer related to what that sprite does.
Most of the bosses have specific handlers, to only show relevant info.
For Cleo, The attack color being used is shown. (not everyone can tell red/green apart.)
For Seahorse Turret, What turret will fire next, is shown by a yellow instead of a read hitbox, along with a counter counting number of frames left before it fires. (If you watch Sivak's latest video showing the challenge runs, in the commentary, he tells exactly how the next one is determined.)

Edit: Barring any bugs, the script should be complete.
Edit: Now shows hit boxes of timmy's shots. Also detects Demo from Version 1.1. Should work on Version 1.0, but can't confirm that, since there isn't a dump of 1.0 out there.
