Danke for finding out where the file was. ^ w ^From what I can find, if you can use SecretiveCactus's conversation editor, you can find and edit the text for Lucina's judgement event in romfs\m\E as 021.bin.lz (romfs being the file I named for all the Fire Emblem Awakening files I have). I believe each 0xx.bin.lz in romfs\m\E are files corresponding to the cutscene text, the xx being the chapter number, while E0xx.bin.lz is for Xenologues and X0xx.bin.lz is for Paralogues, then the rest are mostly just files like ウード_フレデリク_親子.bin.lz (ウード being Owain, フレデリク being his father (in this case, it's Fredrick) and 親子 stating that this is a parent, child relationship) which are character support relationships.
I'm pretty sure I was able to edit the conversation successfully. Now, I have 2 versions of the modded game, one with my custom conversation edits for the judgement scene for if I want to pair female Robin with Lucina, and one without for all other pairings with female Robin. It seemed pretty easy after I knew where the file was stored. Danke so much again sweetie. ❤ mgmwah
