I've been editing the text in Bank 1, but when I go to save I get a Bank 1 overload message. I'm sure it's from me adding a lot in, so I ask what is probably very obvious: when I add text somewhere, I should take out text from somewhere else, correct? That or make sure it's within the same length or the original message?
There may or may not be a small margin for adding in extra text in a given bank but in general, you'll want to delete stuff to make room for adding stuff. The stuff you delete must also come from the same bank; so, you can't for example add a bunch of text to bank 1 and try to make room for it by taking away from bank 3. As for the amount, it's difficult to measure in terms of the number of letters/characters because the game uses a certain kind of text compression and the editor decompresses/compresses it automatically for you, so just because you deleted 10 letters doesn't mean you have room for 10 letters; you might only have room for 5, or you might have room for 20.
Is there a way to expand the rom to add extra space to the 3 main banks of dialogue?
Not if you want to continue using FF4kster; it doesn't play nice with rom expansion and/or moving data around.
Granted, my overload's probably coming from me editing the chocobo messages from one word to a text box full of stuff... haha.
That would do it ^_^
Right now I'm quite new to romhacking in general. Seeing as I've loved this game since I was 4 years old in the early 90's, and it has a nice editor, I figured I'd start off with a decent spoof text hack for my own enjoyment, maybe share it on here once I get the hang of editing things and I've got funny script that doesn't make my banks not want to explode. I'm aiming for the quality of FF5 Spoof, where there's a lot humor, but it's not completely stupid humor or constant sex/porn references like any Chrono Trigger/FF6 spoof I've come across.
Be sure to read the readme though as there are some things that are stored/programmed very strangely in FF4 and it may not be obvious just from using the editor.
