I am new to hacking, so forgive me if these are basic questions that I have. I have looked through some tutorials and have a very basic grasp on what some of the more important programs do (Event Assembler, Nightmare, FEditor, etc.), but there's something I don't quite get: It's stressed that ROMs are illegal to send and not to do it, yet all that I have seen regarding making edits to FE7 involve altering a ROM of the desired game. Is there a way to compile these edits into a patch? So far, I have seen nothing that says/shows how to do this.
Second: As I understand it, pointers refer to specific resources within the game's data (Character portraits/descriptions, conversation images, etc.) and therefore to change say, the background when Lyn is talking to you in the FE7 prologue, you change the pointer from the tent background to whatever you want it to be. My question: Is there a way to view a coherent/indexed list of pointers and what they refer to? How do I know to change the pointer in Event Assembler from 0x00 to 0x18 in order to have Lyn speak against the backdrop of a castle garden instead of her tent?
Any help with these two questions would be most appreciated!
