Casting Spells Taught by Espers - RESOLVED!

From there I was able to realize I used the wrong CMP. I should have used the C3, not D3, and I corrected it with this line.

You should use an assembler. Not only it is easier to use than remembering opcodes values, such an error cannot happen. You also don't have to rewrite large portions of code each time you forgot something or make a change. There's a maximum of 5 basic and easy things (such as the org instruction or what is a label) for a regular use you have to learn that are not related to actual SNES Hex coding, after that it's basically writing code like it is exactly in the disassembly.
