Hello, I’am trying to extract the models from this game (https://play.google.com/store/apps/deta ... .puchiguru) , and I think I’ve made some progress
Fist I downloaded the app on nox player
I started the game while capturing the traffic with the Packet capture app for some reason I can’t get past the start screen with the app capturing packets I disabled it only to get pass the start screen. While a video is playing I activate it again and let it download all data

I checked packet capture and got this

I clicked the 39MB one and I got this

That’s a request and a response is far as I know after the first response I got this one

And this looks like and unity asset file I saved it as a *.unity3d file to open in unity studio and I got this. Not a 3d model but is something

Packet capture let me save the entire conversation (requests and responses) as *.pcap file so I downloaded wireshark, opened the file and try to save it as raw but I don’t really know how to use wireshark and I got here

In theory I can save the received data as raw but it saves either the full conversation or all responses together.
So if someone with more knowledge in this can help me to save every response individually in an efficient way (the packet capture app method is one by one) in wire shark or use another technique to get the models it would be great.

Notes: -I got the game from QooApp searching for pokelabo
-The apps for capturing packets is called packet capture avalible in the play store
-I tried with fiddler 4 but it gave me a 403 forbidden error, maybe I’m creating the request in a wrong way

Thanks in advance and sorry for my broken English.

I’m back and found that the models are downloaded when you get them in the gotcha it was tricky because the app don’t allow some things (scouting and login in) while pakect capture is capturing packages, but I was fast activating and deactivating the app and get this model it has all the textures including the multiple faces, this is a progress but that means that I have to get a character to get its model

Here is the request for this model

It seems like a list of the assets so I thing I might be little closer but If I request this and any other file via fiddler I got a 403 forbidden error, so I think the files need a key or the game “authenticates” (not sure if is the correct term) before you can download a file I think that because of the first request and response I got from the packet capture app in the initial download

That’s a login I think before the download starts so how I can emulate this and to get the files I want or I’m doing something wrong in the request to get the a file, here is an example for the model i got using the packet capture app trying to get it using fiddler 4

So if anyone knows what I’m doing wrong it would be helpful

Thanks in advance.
