Hacking [How to] Create and Use a LayeredFS plugin

[Funky.Art]

Hey everyone ^^ I've got a problem...
I've made a layeredFS plugin to undub my Retail version of Fire Emblem Fates, but when i boot NTR CFW from the CIA file in Emunand Reinand 11.0E, and then launch my game, i have a green screen for half a second, and it just say that a error occured and it reboot... Trying without the undub files, it does the same thing... How can i fix it ?

Download the NTR Pakckage here:
http://www13.zippyshare.com/v/OG29vyMr/file.html
(Inluded the NTR 3.4 with NTR Viewer)

Be sure to have DevKitPro installed:

Put DecryptedExeFS.bin in workdir.
Rename it exefs.bin
Run BuildLayeredFS.bat.
Enter TitleID.
Enter Nothing.

Create 2 new folders:
- 1 at the root of your SD
- 1 in the plugin folder.

Rename them with your TitleID.
Put the plg file in the TitleID folder (the one in your plugin folder).

For the folder at the root:
TitleID = RomFS
Files in romfs should be in your TitleID folder instead.

I used Pokémon Alpha Sapphire as an example.

Be sure to like the video if that helped you

i have tried downloading the dekit pro but it keeps giving me a 32 bit when i need a 64 and it wont run how do i fix this? the screen shot is for the first screen only ignore the second

Same error here, with Star Sapphire.

One thing I somewhat dislike is these guides that raise more questions for someone like me.
"Put DecryptedExeFS" - okay but how did I make a decrypted ExeFS again..? Is there tools for it? Is there some REALLY simple tools for it or whatever?
and so on. I mean sure I am just an idiot but. Eh whatever.
So instead reading this guide I am using mostly time to just figure out what tools handle dumping and extracting and decrypting the needed files which is by far clearly the larger part of making a plugin than whatever you do after you have DecryptedExeFS

Just use Asia81's Hack Pack to extract the contents of the CIA and then you get multiple parts including the DecryptedExeFS...
it's definitely not difficult...

Um I´m confused, where does the romfs.bin goes to?

Any help with this? I keep getting this and no layeredfs file.

I'm trying to get my mods working again for Smash 3ds but I need a LayeredFS.plg to do so
However when I followed the video I can't get passed the part where you run "build_layeredfs" file because it says the application failed to run properly
And it's the skins that aren't working the custom music works fine
It's the textures that aren't working for some reason
Is there anything I can do to get a LayeredFS.plg file by any other means???

If you want to use Smash mods, use SaltySD instead.

SaltySD isn't working for them since they updated Luma.

SaltySD isn't working for them since they updated Luma.

If it stopped working after updating Luma, the problem is likely that they have the code .bin file in the wrong location.

I did finally realize that and I've PM'd them to continue helping them.

I'm stuck on step 1, running BuildLayeredFS.bat with the DecryptedExeFS renamed to exefs.bin in the workdir folder. I get errors saying "No such file or directory", "The system cannot find the file specified".

When the program first runs, section names are displayed as gibberish (non-English symbols) and afterwards it says "Errror, ExeFS section 0/1/etc. size invalid".

Any idea what the problem could be?

Okay, this time I extracted the decrypted exefs with the older Hacking Tool 3DS, not the newest one. No gibberish this time around, but now I get different results from the OP / video:

Instead of asking me for the TitleID, it asks me for the folder with LayeredFS "file" - I simply wrote down the LayeredFS folder (no clue what the "file" is supposed to be).

Idk if it's going to work now, let's try.

--------------------- MERGED ---------------------------

Nvm, I'm dumb - the OP is getting the same instructions as me and still enters the TitleID.

I seem to have done everything now, but how can I know which of the romfs files I should enter into the folder? All of them? That will take a lot of room (~3 GB).
