[Info] Script and batch files to extract the pak files

[robhal]

Original post from FluffyQuack


I looked into the PAK format and I realized the "directory offset" is actually part of each PAK file. The BMS script even reads it, but it does nothing with it.

So here's a better way of extracting the PAK files which should be compatible with any PAK files Capcom adds to the game.

New BMS script (create a text file called sf5.bms and copy and paste this into it):# Unreal Engine 4 - Unreal Tournament 4 (script 0.4)
# Modified by FluffyQuack for better SF5 support
# script for QuickBMS http://quickbms.aluigi.org

# set your AES_KEY here as text or C string ("\x11\x22...")
set AES_KEY binary "_aS4mfZK8M5s5KWC2Lz2VsFnGKI7azgl"

goto -0x2c
idstring "\xe1\x12\x6f\x5a" # 0x5a6f12e1
get VERSION long
get OFFSET longlong
get SIZE longlong
getdstring HASH 20

goto OFFSET

#Acquire base name
get NAMESZ signed_long
math NAMESZ -= 9
getdstring DUMMY 9 #Skip the "..\..\..\" part of the filepath
getdstring BASENAME NAMESZ

get FILES long

for i = 0 < FILES
   callfunction GET_NAME 1
   savepos TMP_OFF

   get OFFSET longlong
   get ZSIZE longlong
   get SIZE longlong
   get ZIP long
   if VERSION <= 1
       get TSTAMP longlong
   endif
   getdstring HASH 20
   math CHUNKS = 0
   if VERSION >= 3
       if ZIP != 0
           get CHUNKS long
           for x = 0 < CHUNKS
               get CHUNK_OFFSET longlong
               get CHUNK_END_OFFSET longlong
               putarray 0 x CHUNK_OFFSET
               putarray 1 x CHUNK_END_OFFSET
           next x
       endif
       get ENCRYPTED byte
       get CHUNK_SIZE long

   else
       # the file offset points to an entry containing
       # the "same" OFFSET ZSIZE SIZE ZIP HASH ZERO fields,
       # just an additional backup... so let's skip them
       savepos BASE_OFF
       math BASE_OFF - TMP_OFF
       math OFFSET += BASE_OFF
       if ENCRYPTED != 0
           encryption aes AES_KEY "" 0 32
           math ZSIZE x 32

       clog NAME OFFSET ZSIZE SIZE

Copy and paste this into BAT file to easily extract all PAK files in one go:for %%s in (*.pak) do quickbms -Y sf5.bms %%s out

You'll also need quickbms.exe and all the PAK files in the same directory for this to work.

Alternatively, just download this which has everything set up for extraction: SF5-extract

Click below to see how to use the SF5-extract (from the download link above)

SPOILER: Click to show

1. Obviously, download it first.
2. Then extract that downloaded file to your pak folder and run the "extract-all.bat".
3. Wait until finish and you see inside your pak folder there is new folder named "out",
4. open that folder and move all its contents to SFV root folder (usually \Steam\steamapps\common\StreetFighterV).
5. Wait until finish and you know the rest (move out or delete all pak files then try to run the game first).
