Well, there's almost nothing in the files that hasn't been uploaded to wiki by now. Except for the avatars. But I didn't bother finding and extracting them. Sooo..

Step 1. Download the game (https://adl.netease.com/d/g/justdance/c/gw_pcclient).

Step 2. Most of game's files are Unity assets files. These are like zip archives. I used Unity Assets Bundle Extractor to open them.

Step 3. Have fun opening random stuff!

The most interesting data is stored on game's servers but I don't know how to get there. Nobody on this wiki knows, except for like 10 people, but they will never say a word about it.
