[PC]Mitsurugi Kamui Hikae - .kpk file decompress

[Weinixiong]

Want to get the resources from this game, so I tried the two tricks below and unfortunately all failed:

First, I used the MKPKUnpacker, it's actually the tool mentioned in this topic(Mitsurugi Trial version. kpk package), which is developed by Ekey. It successfully generated some files but all of them are corrupted, filled up with 0.

 

Then, I took the 2nd way. I downloaded 2 bms scripts, one is mitsurugi_BMS.7zand the other is from aluigi(https://www.zenhax.com/viewtopic.php@t=7187.html). But none of them did work.

Wanna know is there anyone knowing how to fix it? THX

BTW, the game version is 1.1.5.1 from steam, and the data0.tbl and Filename.list I used are from (https://reshax.com/files/file/2340-blender249mitsurugikamuihikae1140gogpcw9o2018-01-06zip/).

You'll need to post a file sample, otherwise it's hard to tell.

I've looked at Ekey's tool in ghidra and I can say that the filename hashing function is regular crc32 bzip2

My bad, here is the sampleMitsurugi_steam_1.1.5.1.rar,having only essential files, data0.kpk and mitsurugi.exe, inside. No full game, so no garantie it will be functional according to how MKPKUnpacker works.

Or the official trial version, due to maximum size of uploading, I'll just paste the download page here - (http://www.zenithblue.info/mitsurugi/pc.html). The japanese word "体験版" stands for "Trial". It requires that you run it in japanese as your system language lest #$%&? will pop up. And once you're installing it, it may just stops on the half way, you can just close the installer, no harms, the main game files have already downloaded, game can be executed, only the updates failed to fetch.
