.pb file from persona 5 pachinko apps.

[aaaaaa]

It made by SegaSammy 777 Town.

It seens had LZSS footer at the end of the file.

 There's are the apk and the .pb files.

I  just asked many more time about this in different discord server.

But no one can extract it.

I used Fiddler to download assets and discovered something about SEGA Sammy Pachinko apps. 

The file index is at:
https://download.777town-sp.net/125/1/data/index.txt.

They download parts of a file as follows:

https://download.777town-sp.net/125/1/data/snfs22_aa.zip  
https://download.777town-sp.net/125/1/data/snfs22_ab.zip  
https://download.777town-sp.net/125/1/data/snfs22_ac.zip  
https://download.777town-sp.net/125/1/data/snfs22_ad.zip

Finally, they combine the ZIP files into a 'pb' using a key URL? likely for decryption:

https://portal.777town-sp.net/pDbg?key=net.sp777town.portal.b.j%23g%3A27&file=snfs22_aa

That's all I know. I hope someone can help me.
