Advance Sprite Palettes

LOL
Hey, no worries man. As far as I'm concerned, if we can't have fun while doing this shit theres no reason to do it.

Good news everyone!
I found the "43 04 00" in the place you said. And changing that 00 seems to have no effect on Edgar's color palette. XD

Okay, so on a lark, I searched for every instance of "43 04 00" in the rom and replaced it with "43 04 01" to see whether somebody's palette would change, or my ROM would explode. Neither happened. I wonder what I changed?

Hmm. Did you make sure to test from before Edgar was already recruited? If he's already recruited, the palette change won't show as working because it's already been set in the sram.
