Naruto Idle Source/Private Server Files

Naruto Idle (Saviour of World / Arashi Adventure / Team Hawk / Triumph of Kage)
Description: I am looking for Source, PS Files, or a walkthrough on Naruto Idle game. I have seen dozens of the same game turned into private servers and I can't find the files for the life of me. I would prefer a walkthrough on how they did it tbh.

Here's a list of all private servers:

1. You must be registered to see links
2. You must be registered to see links
3. You must be registered to see links
4. You must be registered to see links
5. You must be registered to see links
6. You must be registered to see links
7. You must be registered to see links
8. You must be registered to see links
9. You must be registered to see links

The following games are all different versions / different names, but they rotate for safety and receive updates in-game. Can't really tell the real version from the playstore.

Here's a list of all retail (main) games:

1. You must be registered to see links
   (Version 1.2)
2. You must be registered to see links
   (Version 1.2)
3. You must be registered to see links
   Version 1.0.1)
4. You must be registered to see links
   (Version 1.1; can't find playstore link)
