I guess you are referring to the big files that you have extracted from the original dat archive, like 0000000f.dat from main_rel.dat. it's not the same format, indeed this 0000000f.dat file is a sequence of compressed files and there is no index table inside it. so it's a perfect job for offzip: of...

upload both the original and modified audio file, I want to make some tests to know if I can improve the compression ratio or it's already at its max

in this case you are lucky because you already have the full prototype of the function due to the mangled function name: __thiscall CRxAudio::CRxAudio(void) you are less lucky for the fact that you don't have the structure (the H file) of the CRxAudio audio object, but most depends by what you want ...

would be cool to have a key database in the script. considering that the "encryption" is just a plain xor maybe it's possible to do something even using only the archive without exe debugging. let me know all the vis3 games you encountered and which are unsupported by the script. if you ha...

is it "The Kreed" game of the 2004?
the demo of that old game didn't have pak archives

the bad thing I see there is that your new file is smaller than the original (correct) but its compressed size is bigger. I use lzma with maximum compression so similar things should never happen but are you sure you have not increased the "complexity" of the original file? because for rea...

I have tried with all the dat files you provide and everything works correctly, the size of the output folder is close to the one of the archive so it's ok.

I have not understood the last statement, because: "??0CRxAudio@@QAE@XZ" indeed is "CRxAudio::CRxAudio(void)" you can hook or proxify the exported functions of the dll, I have had experience with both although I have preferred the dll proxy solution but it may be not accepted on ...

this is the script for the dat files:

Code: Select all

for
    get OFFSET long
    if OFFSET == 0
        cleanexit
    endif
    get SIZE long
    log "" OFFSET SIZE
next

xwb is the archive of music files, try unxwb:

aluigi

yes you can reimport the files

I don't remember where I posted the original script anyway download the zip here:
http://aluigi.org/papers/bms/other_bms_scripts.zip
and you will find tenerezza.bms
