Braindump makes it very simple just select the game you wish to dump then congrats, however this doesn't work with most eShop exclusive games or at all with 9.6 crypto games.

Decrypt9 if you want to go down the route of just finding the rom online and decrypting it to dump. (If you can't be arsed to dump and convert the game to cia yourself or an eShop exclusive/9.6 crypto game which requires a certain files to decrypt)

Now once you have the ROMFS/EXEFS/CXI(Braindump) decrypted .CIA(Decrypt9) open up CMD.exe enter CD path to romfs/exefs/cxi/cia folder press enter, once there you have various command lines to use.

Braindump(Pre-release)

ctrtool --intype=romfs --romfsdir=romfsdir romfs.bin

ctrtool --intype=exefs --exefsdir=exefsdir --decompresscode exefs.bin

I use the pre-release version of Braindump so I just get the romfs & exefs instead of CXI, but I assume the way to dump the romfs/exefs from CXI is the same as CIA.

Decrypt9

ctrtool --contents=contents RomName.cia

You'll get one or two files with this contents.xxxx.xxxxxxxx the larger one should be the romfs so replace contents.xxxx.xxxxxxxx with that file name.

ctrtool -p --exefs=exefs.bin contents.xxxx.xxxxxxxx

ctrtool -p --romfs=romfs.bin contents.xxxx.xxxxxxxx

Common formats compatible with Ohana3ds Rebirth

BCH
CGFX
BCRES
BCMDL

There may be some versions of these formats that may not work, and some may be in custom container which would require opening the file in a hex editor and removing the container if it's not already supported or compressed.

for more info https://gbatemp.net/threads/wip-ohana3ds-tool.392576/

I'll use Persona Q as an example:

Delete everything above "CGFX" there also may be some QuickBMS scripts that will help, same applies for the other formats mentioned above.

Some may be compressed which you'd have to figure out what compression was used, I believe there also may be some QuickBMS scripts to do this.

Now with all that out of the way, I'll be using a Pokemon model as an example.

Open the file in Ohana3ds Rebirth

Export it as DAE or SMD. OBJ doesn't support rigging.
Export Textures as well only exported as PNG
Now open the model in your preferred software, and grab the origin to make sure everything is weighted also check to see if some of the bones are pulling the wrong vertex's

This one doesn't seem to have any issues, but if you do encounter any weighting issues it's a simple fix with Neosis.(I do this with most things regardless, I suggest you do to as if you don't sometimes the weights will be broken in other software)



Open Neosis, find the file, right click export, and export it to FBX, then back to the original format to fix these issues most of the time. (I've only had a few models where this method doesn't work)
Now repeat the first step and if the weighting is still broken you may need to fix it yourself or find another method.


Now for textures, this is mostly just for Pokemon textures, but may apply to other games. (Pokemon is currently the only game I rip from that requires this amount of editing, most other textures work out of the box or require the texture be mirrored on X/Y)

Apply the textures and it'll more than likely look broken like this:
Open the texture in your preferred image editing software. I'll be using Paintdotnet.

For the body and similar textures.


Copy the texture CTRL+A then CTRL+C

Double the canvas size horizontally
Add a new layer paste the texture and flip it horizontally, or make a new image and flip the texture horizontally.
The eye textures are a similar process, I don't know how ones with pupils work, so if someone who does wants to speak up please do.

Make a new image with double the width and one the same exact size as the original.
Select, and copy the first side of the eyes, then paste it into the same size blank copy and flip it horizontally.
Now paste it into the image with double the width and move it into place, make sure to be pixel perfect, do the same with the eyes on the right, then repeat until it looks like the final image on the right.

The Eye's normal maps are simple, just increase the canvas size to match the final eye textures, then copy the texture in all the blank spots as such.
Then repeat all this for the shiny textures and any similar textures.
RTB's Explanation might be better.
Eye UVs:
for Blender select the eye mesh's UVs and open the UV tab then press X and -192, that should be the perfect number to fix those UVs. This might not be necessary all the time.

This will only be for exporting in Blender

Press A in the viewport to select everything, make sure to deselect anything that isn't the mesh and armature, then go to File > Export Collada (Default) .dae.

Blender doesn't seem to like exporting from SMD sometimes, so the weighting my not work when importing the .dae to fix this repeat this with the newly exported .dae (this issue mostly occurs with Pokemon & Stella Glow models, and rarely I've found anything else)

Open it in blender again, make sure it works, apply textures, and delete any extra armatures that Neosis may have created then export again.

Check if everything works again then open the .DAE up in your preferred text editor and remove all instances of file paths.
If you want to include an FBX version use neosis to export the dae/smd to FBX with the flip UVs option enabled. (might not be necessary, but the UVs have always been broken when exporting to FBX without flipping UVs)

Make sure everything works correctly, then render icons with transparency 148x125 & 750x650
