Nitroplus Blasterz: Heroines Infinite Duel (PS3/PC) - extracting graphic resources

[Lucas Hood]

Hello everyone. This is my first time to this forum. I came to this place as a replacement for the previous Zenhax. So long story short, I am working to rip/extract the graphic resources from a fighting game called Nitroplus Blasterz Heroines Infinite Duel, such as the character portraits, the game event CG/artworks, and the movies of characters showing their special moves (if possible). For months I've went to various places and asked everyone that I know but to no avail, they have no idea how to decrypt the files or extract them, and I don't know any tools that can assist me with this task. The game has some kind of in-house engine, making the reverse engine process even more tedious. For information, this game has PS3, PS4, and PC format, each has different type of encryption. The files in PC version are all named in such a complex manner that I have no idea what type of files they are nor do I know what they contain. You can see them in this screenshot.

The PS3 version, on the other hand, has a better view where I can read the names of the files, although I'm still uncertain which files contain the aforementioned character portraits and the event CGs. Here is a screenshot of the PS3 folder.

I've been dying to get those beautiful assets but so far I got zero luck, hence I sincerely hope I can get some help from everyone here. I'll be forever grateful to anyone who can help me extracting/ripping those resources.

Here is the folder which contains several example files, both in PS3 and PC version. Regarding the PC version, since I don't know which file has what I need so I just uploaded the largest files from the game. Please let me know if you guys need more files or more information about this game. Thanks for reading and much appreciated.

The character portraits in particular are like this. They are commonly used in the story cut-scenes of the game.

As for the event CGs, they are these. Do note that the CG album that the OP posted are just screenshots, they are not actual images ripped from the game.

Edit: Please don't suggest Ninja Ripper for this game, my goal is to get the graphic assets in their original quality, not capturing frames/textures one-by-one. Regards.
