Marvel Mystic Mayhem - .pck files

[boopsnoop]

Is anyone able to help extract the art asset files (sprites, textured2ds) from Netease's latest mobile game? Using AssetStudioGUI out of the box doesn't seem to work.

APK: https://drive.google.com/file/d/1AqAQ3jRVK66fnDIqrByA77LEWNaIMXga/view?usp=drivesdk

Also would love to hire someone on a regular basis for these kind of things, hmu if interested!

specify Unity version 2021.3.41f1 and use an AssetStudio fork that can bypass fake headers (either RazMoth or aelurum).

Not able to get it working. Here's my step by step:

1. extract apk with 7zip
2. open razmoth's version of assetstudio and specify 2021.3.41f1 as the unity version
3. load a file from Marvel MM_com,netease,mmm_1,1,31\split_UnityDataAssetPack\assets\common like ui_image__charactericon_sp.pck

Get the following:

# AssetStudioModGUI v0.18.0.0 [x64] [.NETCoreApp,Version=v6.0]

I probably missed or screwed up a step, any ideas?

How did you do it? I still get "No Unity file can be loaded." when trying
