Hello!

A friend and I have been trying to get into the main archive of Yo-kai Sangokushi for Nintendo 3DS for a while now.
The file types are completely different from the other Yo-kai Watch games because this game was developed by Koei Tecmo. I've modified the files in Busters/Busters 2 before and I'm familiar with Level-5's .fa format, but Sangokushi uses KT's .BIN compression format for it's main archive

I can't for the life of me figure out how to get into the file, so could anyone here potentially help me out here/guide me in the right direction on how to extract and repack this file? I'm not very code savvy, but any help would be greatly appreciated.

LINKDATA_A.BIN file: https://drive.google.com/file/d/1It2yy8rYCYldFGnDuRVHeMlS_Gti5HGp/view

Have you already tried this script?
http://aluigi.org/bms/arslan.bms

Another alternative, in case that doesn't work, is http://aluigi.org/bms/dynasty_warriors_4.bms

Tried out both scripts. I had to modify them slightly and remove the line for IDX files because this game doesn't have one.
arslan didn't do anything and stopped before anything could be extracted, and the DS4 script extracted a little bit before it stopped due to not being able to read after a certain offset (the coverage was at about 1%)

All of the .dat files it pulled don't work, but a few .dc5 and .fnc files did get pulled out, but I have no idea what to do with them.
I also got a few .txt files, but they were all garbled and unreadable.

I've tried other scripts for KT games in the past but none of them work because I'm pretty sure each game is unique in the way it stores and compresses things, which makes it impossible to get into the files unless you write a script specifically for the game you want to get into. :\

Worked like a charm! Thanks!!

Hello sorry for the bump, but this is the only script I've found for Koei's Linkdata BIN files without the IDX pair. I'm looking to extract the Pirate Warriors 4 BIN files, they contain the texts from the game, I used the script and got some files but there are sectors that seem unintelligible, I don't know if it's because the script isn't compatible or the encoding of the file.

G... I'm so dumb, never noticed I deleted the file, here it is again, sorry for making you lose your time.
