Changing which monsters come from eggs

[Odal]

I'm working on a monster-based patch and I'm curious if there is a way to make monsters breed any other monster eggs outside of their own monster class.  The way this I want this to work is to remove the family aspect of the monsters.  The only thing that binds this together that I can see is that monster number 1, for example, is going to lay eggs for only monster number 1, 2, or 3 and monster number 4 lays eggs for monster 4, 5, or 6 etc.  I'd like if any monster egg can hatch any other monster 1-48. 

And if this is not possible, is it possible to remove egg laying entirely?  I'll be glad to leave it to taming them to get more if I have to.

You need to ASM hack it.

Here's the starting place:

http://ffhacktics.com/wiki/Create_Monster_Egg

The first function calls the second. I think the second tries to add the egg to the party, and the first actually decides the ID of the monster.

I don't remember who made this hack, but this disables monsters laying eggs:

Thank you for the responses.

I'm really not sure where to even start with this.  I'll probably just use:

Also, another somewhat related question.  Is there a way to change monsters' UNIT.BIN resolutions?  Some monsters use the typical 24 x 40 while others use 48 x 48.  I could possibly work around this if I were using all 24 x 40 sprites, but I'm using sprites which would need the 48 x 48.  So, for example, I'll need to replace the goblin UNIT.BIN file with something which is 48 x 48, but fftevgrp won't allow me a resolution different than what is native to goblin (24 x 40).  Can this be changed?
