Coding Questions and other Quandaries

[Hackwiz]

First code making use of the LR. Infinite health.
Because of where I was at at the time, when I first started fudging around with this game, all I was able to do was give myself infinite health, along with the enemies

Had to use two different checks with LR so the game wouldn't freeze during cutscenes etc.

Has worked fine as far as I have gotten into the game

Let me know if you see any craziness in it.

Specifics:

LR = 0x80073798 During cutscenes/intros
LR = 0x800798E4 When taking damage
