So, since progress regarding the ripping of this game was pretty short-lived, to say the least
, I decided to handle this by myself.
Thanks to Yuzu's RomFs dump feature, I was able to get all the files with no trouble.
However, I have found out that they are encrypted in a possibly propietary file format (ranging from .osb to .bfb, .stb, .scb, .ttb and .bfgrp)
Any way to open these?
Google Drive folder with all the dumped files
UPDATE: I decided to extract the files from Bloodstained: Curse of the Moon, Dragon: Marked for Death and Blaster Master Zero 2 as well (also by Inti Creates) and it appears to have the same file format too.
Azure Striker Gunvolt Striker Pack
Bloodstained: CotM
Dragon: Marked for Death
Blaster Master Zero
Blaster Master Zero 2
