job done and I have even improved the script allowing it to work with more games and different versions (like all the builds of pCars):

send me a pm with the x360 executable (or whatever platform it is)

2 suggestions:
- "writed" -> "written"
- "\x50\x41\x43\x4B" -> "PACK", it helps to find the script on google

if the dat was inside those you extracted with the script it's a file and so not for me

md5 is an hashing algorithm, not an encryption one.

I have noticed the 8bytes alignment so I think to blowfish

for the BfPk files I have an experimental script. translated: it works for extracting some files, then something with the offset becomes wrong. endian big idstring "BfPk" get DUMMY short get OFFSET short get FILES short get DUMMY byte get DUMMY short math OFFSET += 1 math OFFSET *= 0x800 f...

anyway it's just a sequence of zlib compressed files (offzip job).
there is no header or index table

I have some doubts and/or suggestions: the domain pcgamingwiki.com has been created the 09 Feb 2012 and has a validity of only one year. I understand the automatic renewal but it's rare to see a website with a long-term vision setting the minimum time for the domain moreover if there is a community ...

is this spam or what?

probably not, it was just the post to have been written in a form used often by spammers here on the forum
sorry for the misunderstanding

do you have a small sample to write a script on the fly?

the algorithm is different.
the correct decompression algorithm is in quickbms\src\yuke_bpe.c
I don't have the compression one.

I'm really curious to know what Microsoft Excel has to do with the binary editing of an executable or a raw files.
I didn't know it became a magic tool to do anything in the world...

I have fixed the original script so that now it's a lot faster and uses less resources (I forgot the classical "putvarchr MEMORY_FILE4 TMP 0").

if you want the temporary file solution:

fixed, was exactly that thing: ZIP field and DUMMY
oh well, I had 50/50 of success :)
