Can anyone walk me through how to edit Units' personal skills and a Class' weapon access (e.g. Nohr Noble gets access to bows). I've got the Good Guy Garon patch installed and would like to keep that working side by side with these modifications. Thank you very much!

Easily done with Nightmare. Open your GameData.bin.lz tht is located in the romfs\gamedata folder (NOT the one in the "m" folder) with Nightmare. Use the character module to change personal skills (changing what each skill does requires actual coding. crack open the code.bin if you know assembly).

Class weapon access is changed in the Class module, though the animations might be funny depending on what classes you give what weapons. To choose which animation a class uses for a weapon type you'll need the AID editor, which can be found in the discord channel. Without the AID editor the game will use the default animation for the weapon type, which for bows are the archer animations iirc.

This should be fully compatible with good guy garon.

Thank you for taking the time to reply! Am I supposed to dump the gamedata.bin.lz file? If so would you be able to briefly explain how I can do that? I made an imgur album with the romfs folder that I found; although I'm not sure if its the correct gamedata.bin.lz file I need to edit.

EDIT: Turns out I can't send links as a noob poster - I'll pm it to you

Hello, I'm using Thane16's randomizer, I have all the DLC files, and I would to love to know how I could add those dlc files to my folder so I can then add it to the Luma folder to use in game, using the FEAT/Randomizer tool. Thankyou mates, and I'll leave a screenshot of what it looks like currently,
do gyazo(.)com(slash) fe13689f4024f4320e30f6ab8052d6e2 for the picture
thanks ;)

I've never done so myself, but I found these instructions which look quite simple if you have the required tools working: https://github.com/citra-emu/citra/wiki/Dumping-Game-Cartridges.

The GameData.bin.lz in the gamedata folder is the one you want to edit - see pic. The other GameData.bin.lz is in the m folder which you do not want to edit.

I tried mounting the CXI to a drive via Godmode9, but could not paste the modified gamedata file to it. Is there a way I can edit it on my computer itself?

Nightmare runs on your pc. If you have the gamedata file on your pc already you don't need to dump it.

Hey, bit of a dumb question but how would one change a character's name in FE fates, through editing? I'm not talking about the Avatar. Also I'm having difficulties using the support editor, I'm trying to open the gamedata.bin in my game data folder, but it says it's an invalid gamedata.bin even though it works with the nightmare editor.

To change a character's name you have to edit their name label which should be in the Gamedata.bin.lz text file in the m/ folder. You can just use FEAT to decompress it into a txt file and tinker with that. The labels names are formatted has MPID_(japanese name of character here). After the label should be the name, just replace it with what you want and drag the txt file back into FEAT. As for supports, I have heard the support editor is broken in the latest version, so try some older versions to see if that works.

Hi! Forgive me if this is a dumb question, but I was curious: is there any way to view all of a character's quotes (such as what they say at the Ore Mine), without having to play for hours? I've looked on the Fandom site, and they don't have anywhere *near* all of the quotes, though it seems like thy're working on it.

Possible yes. All text is stored in the GameData.bin.lz file saved in the romfs\m\@E folder. You will need to extract it with FEAT (https://gbatemp.net/threads/feat-fire-emblem-archive-tool.391685/) and can then view it as a text file.

In order to get the gamedata file you will either need to dump a fates rom and unpack it (use https://gbatemp.net/threads/release-net-3ds-toolkit-extract-and-repack-3ds-roms-and-cias.444427/ to do that) or use one of the modified versions of the file that some hacks provide (such as the gay hack, good guy garon might as well), though this will have the obvious issue of being different in some ways from the base game.

So, I got FEAT, and I got one of the hacks, but FEAT won't extract the GameData.bin.lz file. When I open the file in FEAT, it simply doesn't do anything. What could I be doing wrong?

Wondering how to edit character aids and make weapons usable on characters that can't use them.
(EX. Axes can be used by Snipers and Personal weapons can be used by everyone.)

So I've started a Fire Emblem Fates randomizer run and I want to try and either get supports back for characters who have lost them (such as people who replaced the amiibo units in hero battles) or just unlock all the child paralogues. The first is preferable, but I'm good with either. Unfortunately, the only hacks I can find for this modify the gamedata.bin, meaning that they would ruin the randomizer modifications. Is there a way to fix my supports/unlock my paralogues without scrapping the current run? I'm using Citra if that means anything, since a lot of the instructions for using hacks I find are based on using NTR or Lumi or other programs I know nothing about to modify the 3DS.
