Hello, everyone. I've only just recently picked up the use of Nightmare to make edits to FE6's relatively unbalanced nature, (yes, I know it's been done many times before,) and I've read through Blazer's guide on how nightmare works (only skipping information about music editing and the like.) I've been strugging to understand how I would go about removing Roy's forced promotion in chapter 21 / 21x and switching it over to chapter 16 / 16x. I assume it would have something to do with the respective chapter's events, but I am not sure how I would go about figuring them out. Of all the things I wanted to do to the game, this is the only block I've stumbled upon that I, as a newbie to the FE-editing scene, cannot figure out.
TLDR: How would I move Roy's promotion in chapter 21/21x to Chapter 16/16x using Nightmare? And, if this is something that cannot be done in Nightmare, what programs do I need?
Thabks in advance, sorry for the text mountain.
