Can anyone have a look please here on this archive ? It is from X360 version.

This is the same people who made yakuza.
They use an unkown lzss compression.

[aluigi]

*sorry, my error*

[chrrox]

i get this error
invalid command "while" or arguments -1 at line 37

[michalss]

so is there any chance to unpack/repack/reimport ?

[aluigi]

don't consider the post I deleted, I made confusion with another topic.

I have seen the files and yes they are the same of yakuza 3 viewtopic.php?f=21&t=5061 so there is the problem of the SLLZ compression algorithm.

in the meantime I have created a script based completely on the code made by MrAdults that may help who is working on this format:

Code: Select all

comtype COMPRLIB_RLE3   # wrong algorithm!

math foldNames = 32
math fileNames = hdr_numFolders
math fileNames *= 64
math fileNames += 32

math fileInfos = hdr_filesOfs

for i = 0 < hdr_numFolders
    goto foldInfos

the chosen compression algorithm is NOT the correct one but it's enough close so you can continue your tests.

[michalss]

thx aluigi, but is this can be normally use or we have to wait for some modifications of the script?

[aluigi]

it doesn't work with the compressed files, so it's of no use or maybe partial use.

I have posted it only for giving a chance to extract the uncompressed files and studying the compressed ones, so nothing "stable" because the compression algorithm remains the only problem

I tested many archives and non of them work . Aluigi did u test it on some archive posted by me ?

[aluigi]

here it works with all the files you provided.

are you sure you are not using an old (very old in this case) version of quickbms?

DUMP Shame on me mate sorry for that update it and now it is ok:) thx mate again

[michalss]

all i care about it is archive file call font.par, which can be unpack ok, but its giving some strange DDS files and it cannot be open Any idea anyone pls ?

Code: Select all

[aluigi]

the strange dds files are probably those compressed.
as already said it decompresses them using a wrong algorithm ONLY because who wants to work on the real algorithm can have a starting point.

[michalss]

anyone working on it pls ?

[chrrox]

the problem is its an unkown compression th eonly way to get the compression is to reverse the game on a devkit xbox 360.
there are several files that include compressed and uncompressed versions of the files in yakuza 3 but i dont hink even that would help to much with reversing the compression.
