I need help to extract building and map from Pokemon US/UM

[Laraja25]

I’m trying to start a project where I need to view the buildings and other structures in 3D from Pokémon Ultra Sun.

So far I’ve managed to dump the game and extract the RomFS, and now I have the folder called “a” with many numbered folders inside it. The problem is that I don’t really know what to do from this point.

All the files I extracted appear as .bin, and Ohana3DS Rebirth can’t open them. Because of that, I’m not sure if I extracted the files correctly or if I’m missing a step.

What I’m trying to do is:

• find the 3D models of buildings and map structures

• open them so I can view or export them

The problem is that I have no idea:

• where the buildings or map models are located

• which files correspond to maps, towns, or objects

• how to properly open the .bin files

If anyone could explain the process step-by-step, or even record a short tutorial video, that would help a lot.

If that’s not possible, I would still really appreciate any advice about:

• what tools I should use

• how to identify the correct files

• where the map/building models are stored in the game

Also, if this isn’t the correct place to ask about this, please let me know where I should post instead.

Thanks in advance to anyone who can help!
