Hi this is my first tutorial I might not be clear so post a comment if you don't understand ^^.

Required:
Braindump
Gimp or some other program with colormap
Hans (Homebrew app, comes w/ Ninjahax 2.5)
HxD (google it)
Pack (extract the rar. with Winwar)
Ohana3ds
GarcTools (install GARCTools and GARC Unpacker)
A REAL COPY OF POKEMON ORAS, DIGITAL OR A CARTRIDGE
Homebrew 2.5

Romfs Location:

OW models = a/0/2/1
In-Battle models = a/1/3/3
Map models = a/0/3/9
Map Textures = a/0/1/4

Steps:
1. Download braindump and put it in the 3ds folder on your SD card. Launch homebrew and run braindump. It should extract the exefs and romfs from Pokemon ORAS. Make sure to have enough space on your SD card. The exefs and romfs take about 2 GB.

2. Once it's done with the extraction, turn off your 3ds and insert your SD card into your computer.

3. You should find the romfs and exefs files, which should be in this 18 character folder at the root of the SD card.

4. Now with the pack go to Pack English v3.6--->Pack Hack--->RomFS extractor. It should take some time for it to extract it. You probably want to move the 18 character folder with the exefs and the romfs bin from your SD card to your computer if you have no more space.

5. Once that's done a "romfs_" folder should have been created in the 18 character folder. Open up GARC Unpacker and extract whatever your editing, in this case the OW models. So click "Open" and go to a/0/2/1 and extract. The "Auto Extract on DragDrop" and "Only Un/Decompressed Files" should be ticked off. Then press "Go" and wait.

6. There should be a folder now in a/0/2/1 that was created "1". Open up Ohana3ds, click "Open" and go select a bin file in it. Press the left and right arrow keys to move to another file in the same folder.

Note: (ORAS) There are two May/Brendan models that have a snorkeler mask. It is suggested to use main characters seen throughout the story.
171/314: May
172/315: Brendan
173: Contest May
174: Contest Brendan
316: Bicycle May
317: Bicycle Brendan

Recolor:
Once you found the Brendan/May model go to Textures and extract all.Open up your Gimp or program with colormap. In gimp open up the extracted images and go to Image-->Mode--->Indexed. Then just click Convert with "Generate Optimum palette". Colors-->Map-->Set colormap. Then just edit the colors. Make sure you have 255 colors in the end product of the texture. In Ohana3ds, click import and import the new recolored texture and click save.

Model Swap:
Just find the file you want to play as. For example, Wally which would be file 181. I would just go to the "1" folder in a/0/2/1 and find file 181 and change its number to 172 to overwrite the Brendan file.

7. Once you are done editing, go to GARCTool. Click "Open Folder" and got to a/0/2/1. Then click "Process". #_.garc should have been created. Delete the file that has the same # as #_.garc and rename #_.garc to #. So 3._garc would be renamed to 3 replacing the old one

8. Once thats done, go to the pack-->pack hack-->RomFS Builder. Open up and find the romfs_ folder and press go.

9. Bare with me, it's almost done! Now open up HxD and open the romfs file that was rebuilt. On the left side it should say "Offset (h)". Scroll down till you see FF0 under the "Offset (h)". Highlight that row and highlight till you reach the top, 000. Delete all those offsets. Save the romfs. Make a "hans" folder in the root of the SD card. Place the new romfs file there. Rename you rom based off the 8 characters on the right side of the 18 character folder. Must be all caps.

Then remove your SD card from your computer and put it in your 3ds.

10. Run homebrew and click hans. Run the Pokemon ORAS app.
Region, Language, FW, Clock are optional
Code -> SD: NO
Romfs -> SD: YES
Save configuration: Optional

Click OK and volia you are playing a romhack.

Does this not work with a pirated version of ORAS? I have digital AS on my clean N3DS and pirated OR on my A9LH N3DS, and I plan to do it on my A9LH N3DS

It should work, as HBL can target digital titles

EDIT;

Hmmmm. I probably did something wrong, but I extracted the DecryptedRomfs.bin that showed up when I extracted the CXI file. I then dragged the extracted romfs file into GARC Unpacker and an error pops up saying it's not the correct format and such

When I open a .bin file in "1", it always give me an error saying it's not a model file. When I open it in Ohana3DS Rebirth, everything loads but it doesn't import file. Can someone explain to me what to do?
