ROM Hack [WIP] Fire Emblem Fates Support Editor

supports for an existing character and adding a new one

Spoiler: my dilemma

View attachment 56488

Yeah, that's a little odd. When you select your GameData.bin, that prompter at the top should change from "Please Select GameData.bin" to "GameData.bin Loaded." It looks like something got messed up during that process - it's definitely a bug. I'm actually having trouble reproducing it though. Do you remember what you did before you encountered the bug? Everything shows up correctly for me when simply opening a GameData.bin and clicking on a character.

Alternatively, it could be an issue with your Supports.xml, as I've already found some odd behaviors with that file. You could try replacing your Supports.xml with the one that came with the download and see if that fixes the issue.

Could I see the GameData.bin that you're using?

knock yourself out

Well, there's your issue - you haven't decompressed your GameData.bin, so the program cannot read it correctly. You'll need to use something like BatchLZ77 to get the file into a format that this program can read.

But looking back at it, there's some serious issues with how my program's reading support tables - it's not quite reading your GameData.bin correctly. I know what the issue is, and I can fix it in the next version, but if you want to get around it right now I'd suggest using the GameData.bin that comes with the Gay Fates hack, as there aren't issues with that version. Sorry about the issue.

i see. do you have a link to BatchLZ77 ?

You can get it here.

Open the file in a hex editor and delete the first four bytes, then try to decompress it.

 

[MsMidnight]

alright

it works! do i compress as normal once im finished with my edits?

I think that you'll have to do some extra steps. Check out step 12 in this guide for instructions on how to compress the file correctly.

EDIT: Nevermind, fixed the issue.

Is it possible to add more support space for an existing character?

also how do i use the nightmare modules ? its confusing me

This can be done, all you have to do is repoint the character's support table to a location with more space. I can try and walk you through that process if you want me to.

What part of the modules are you having trouble with?

 

[Juelz Proasheck]

Yes! I'd greatly appreciate the help.

everything. im tryingto load .nmm

Alright, it's not a very difficult thing to do, but it could be a little intimidating if you aren't used to hex editing.

1. Open your GameData.bin in a hex editor and navigate to 0xADF0. This is the pointer table used for every support table in the game.
2. In order to find the support table we need to move, you'll have to locate the pointer to it in the table. Each set of 4 bytes after the first set is a pointer (the first 4 just indicate table size). The first list in this guide is the order of characters in the table. So for example, the bytes at 0xADF4 point to Ryoma's table, the bytes at 0xADF8 point to Male Corrin's table, etc.
3. Before we go to the table, you should record the offset where you found the pointer, because we are going to have to change that pointer later. Once you've done that, navigate to the offset indicated by the pointer (flip the bytes around, so if the bytes are D7 2F 03 00, you navigate to 0x32FD7). When you get there, move two lines down and you should be at the table. You have to move two lines down as everything in GameData.bin is offset by 0x20.
4. Copy every byte from this table and move it to your new location. Make sure that when you move the table, you overwrite existing bytes, DO NOT paste insert. Paste inserting will break other pointers in the game, and likely prevent your game from launching correctly.
5. Go to the start of the table at the new location, and move two lines up. Note this offset, and flip it around so that you can get the pointer for it. So if my new table is two lines below 0x23B10, the pointer would be 10 3B 02 00.
6. Go back to the table at 0xADF0 and find the pointer that you followed to the original table. Change it to the pointer to your new table.
7. You now have space for new supports!

I'm not sure that I'm following you. You just have to open your decompressed GameData.bin, then the Character.nmm file that comes with RainThunder's nightmare modules.

What locations in GameData can be overwritten?

 

[thane98]

What locations in GameData can be overwritten?

Anywhere with a bunch of empty bytes (if you see a lot of 0xFF bytes and nothing else, that's probably an empty space that can be overwritten). If you can't find any of those, you'll have to expand I could also show you how to expand GameData.bin so that you have more space for tables.
