help with Berserk Musou sound files

Hello everybody.
I'm completely new to the world of extracting videogame files and recently i've found myself needing to obtain the sound effects from Berserk Musou (Berserk and The Band of the Hawk) and after hours of searching, i've come up completely dry, the "linkdata" (which have .A, .B, .C and .D file extensions) files i managed to unpack using quickbms and the omega force script, however it just gives me a bunch of .dat files that when checked using TrIDScan, all come up as unknown, as opposed to the .dat files in the 'RES' folder of the game, these files do not play when i view them in VLC, the ones in 'RES' are cutscene videos that I can play normally, but these aren't. A lot of the files are 0kb so I'm thinking maybe I used the wrong script? I don't really know.

I also tried searching online to see if anybody had already extracted the sound files, and I couldn't find anything, only someone who managed to rip the models and I've shot them a message, but I haven't many hopes of getting a reply back. If anybody knows, please do help!! again, I apologize for my lack of knowledge.

let me know if i should send any files or anything and i appreciate any and all forms of help. thank you!
