Is this the full file?

This script does about 40% before erroring

Yes, it is the complete file. This script was made for the Tenchu Shadow Assassins file, but it doesn't work 100% on Samurai ...

Change the line 8 of the script and see if works:

Code:

get FILES long
get FILES long

for:

Code:

get FILES long
get DUMMY long

It's so weird.
There is a FLAGS field that if equal than 2 or 4 gives some problems since the SIZE doesn't match the size in the archive.
Indeed it can be smaller or larger than the original size but I don't see a real compression used, the content of these files (whatever flag 2 or 4) has often clear content.
I updated the script for dumping these files as-is using the whole size in the archive.

I noticed when using the new version of this script on Way of the Samurai 2, the script
ends abruptly with an error as well, whereas the old version of the script worked fine. Perhaps the
old version will work with Samurai western.

Here's the old version of the script

Code:

# Hakuoki Shinsengumi Kitan / Way of the Samurai 2
#   maybe other games developed by Idea Factory
# script for QuickBMS http://quickbms.aluigi.org

endian big
idstring "\xfa\xde\xba\xbe"
get FILES long
get FILES long
get DATA_OFF long
get DATA_SIZE long
for i = 0 < FILES
    get NAME_HASH long
    get OFFSET long
    get SIZE long
    get ZERO long
    get NAME_OFF long
    get NAMESZ long

    math OFFSET   DATA_OFF
    math NAME_OFF   DATA_OFF

    savepos TMP
    goto NAME_OFF
    getdstring NAME NAMESZ
    goto TMP

    log NAME OFFSET SIZE
next i
