So this is really starting to get on my nerves. Not because I have any big plans for ROM hacks or anything, simply because more than one person has claimed they have done it (and I've seen it in Tyranitar's Extreme Sun Randomizer [How the game has edited starter overworld models for instance]). So that tells me that it is possible.

Now, I have had at least two people attempt to give directions but there was a bit of a language barrier so they aren't exactly specific in the least.

For example, the overworld models/textures are located in the a/0/8/3 garc in Pokemon Moon. However, anytime I attempt to edit anything in this garc, my console either crashing with an arm9 error or it restarts itself completely. I know for a fact it has everything to do with the way I am repacking everything because I unpacked the garc, and the bins, extracted the files, and packed everything back without making any edits and I get the same result.

At this point I can't even determine if my edits are bad or not since my packing method is so obviously the issue. This is what I was vaguely told to do; heavy emphasis on vague.

  • I use PK3DS to unpack the garc file from a/0/8/3.

  • This gives a number of .bin files that correspond to a map location.

  • The "003.bin" file contains models for the Route 1/Outskirts maps.

  • I take the "003.bin" and decompress it using the "(de)compress LZ11" option in PK3DS.
  • This gives me "dec_003.bin".

  • I then take that "dec_003.bin" and drag it to PK3DS. It asks if I want to unpack "sub files" and I say yes.

  • This gives me a folder called "dec_003_AC".

  • Inside here there are 26 folders, and 26 .bin files.

  • The "13_CP" folder contains a "1_CM" folder as well as two .bin files.

  • The "1.*******" file inside the "13_CP" folder is the model w/animations and can be edited. So I open it in Ohana BCH and replace the textures and save it.
  • Then I open the "1_CM" folder and do the same thing for the "0.bin" which is just the model/texures.

  • Now, I take that "13_CP" folder and drag it the garc tools window in Ohana, and it becomes "13.CP"
  • I rename this to the original file in the garc "13.*******"

  • Then I take that "13.*******" file and drag it to Ohana to unpack the sub folder and get the "13_CP" folder back.

  • Then I take the "dec_003_AC" folder and drag that to the "repack" window in PK3DS.
  • It becomes "dec_003.AC"

  • I take this file and compress it with the (de)compress LZ11 option and it becomes the original file "003.bin".

  • Finally, I drag the edited garc to PK3DS to repack it.

I know this is a little long winded, and I apologize but this is driving me absolutely crazy and I would love to know what I'm doing wrong. Or even if I need another version of PK3DS someone could supply. I would be eternally grateful for any assistance.

Even if you haven't tried, if you're seasoned in ROM editing I could use some more heads to try and help me figure this out. When that does happen, I plan to write another tutorial for NPC/Pokemon overworld texture edits. Thanks for taking the time to read and if you can help please do!!

It only works on Citra from what I've heard.
Hmm, I've been able to do building textures, Cutscene NPC textures and Battle NPC textures....... I guess that would make sense but I find it odd that the building textures work just fine and they are "nested" the same as the overworld models....

Thank you very much for the reply. This very well could be the issue, so I might be wasting my time. I'm just now wondering if that's correct, why wasn't I told during the instruction process Lol. It would have helped.

That's why I'm hoping someone else is willing to give it a shot. Otherwise I have no way to know whether; it's not possible on the console, what I'm doing wrong when repacking, or if there is something else I'm overlooking.

it should also workon 3ds

im gonna try to edit over world sprites
Please let me know what you find. @Traiver said he was going to attempt it too so I am still awaiting his report. I just hope we can all get it figured out before UsUmO comes out. It's namely so I can write a tutorial since everyone has been wanting to at least edit the textures since we can't swap the playable character.
I've just been basically trying to figure it out alone for the past several days to no avail.

TyranitarTube paid someone to made the rom, he didn’t do anything
That someone is sure an expert and know how to modify the games, he managed to mod the code inside ORAS to make every change working

I realize this but unless the people used private tools, (which they could have) anyone can do the same thing. Regardless if he paid someone to make it impossible. I'm not trying to "recreate" his randomizer or anything. There is a thread for that already. I'm just curious about the NPC models.

Well I’m not saying you shouldn’t do anything, I was just stating

And double check your folders, maybe that’s why you keep geeting this error

Thanks. I have many many times. I didn't just do it once or twice, more like over 30 times in the past week. Hence my frustration. I've tried many many variables before creating a separate thread. :(

Most of these types of edits do not work on consoles period. The overworld models and NPCs can only be edited to work with Citra.
Not true
I've been tried to play on Citra after packed my ROM
Everything is fine until the 3rd island when no NPC Textures (Even mine) we're popping
Even some of world textures were black
I was Walking on nothing and my character was not even visible.
I repacked my game the same method and it still give me this
And this is not a Citra Issue because when I try to repack the game with a clean A/0/8/3 , textures work perfectly fine
