I've made a program that does the all of that for you. It asks you for information about attires, IDs, etc. and produces the hex bytes for you! You simply have to copy them and paste them at the correct offset. I'd highly suggest reading the tutorial once though so you know what you're doing

So have fun, you lazy cats.
