Help with overworld sprite palettes!

[xDaygo]

I've scoured through a number of posts so far, but none seem to help me out. Essentially, all what I want to do is switch Shadow's overworld sprite palette to 1 rather than 4, but I cannot for the life of me figure it out. Hex is extremely foreign to me. And I would definitely appreciate and tips toward the right direction on this one.

According to FFusME: "FF3us, Version: 1.1" and "ROM is header-less: no"

Also, I should mention I currently have HxD (dunno how to use it tbh), FFusME V6.80, and RuneLancer's "palette_locs" document.
