Somebody help me!

You can see filenames in plaintext, this is not a compressed file. If anything that's a file table with offsets/filesizes.
Do you know how to use QuickBMS, did you try it at all?

Hi, Insanius
Thank you for your interest

I know about use QuickBMS, but i can't make bms script.
I just did offzip, but nothing happened.
I am just a newbie, so i need your help.

A merry Christmas to you!

Ok here's what I figured out, all numbers are in big endian:

4 bytes - Signature
12 bytes - Header Data (unknown)

Begin file table

4 bytes - File Offset (From end of file table)
4 bytes - File Size
4 bytes - Filler
2 bytes - File entry length (M)
2 bytes - Filename length (N)
1 byte - Filler
N bytes - Filename
M-17-N bytes - Filler

One of the numbers in the header should be the file count, you could discover it through trial and error at this point.

I certainly appreciate your helping me out.
I'm very sorry!
I am new at this, and i can't understand what you're reply.

I need some help solving these.

I am not sure where they are getting the start offset from but if there is only one big archive it does not matter.
this will extract that file for you.

Code: Select all

#Quickbms Script
#By chrrox
endian big
goto 0x8
get files short
get unk short
get start short
get null short
savepos tbl
for i = 0 < files
goto tbl
get offset long
math offset + 0x43000
get size long
get FFFF long
get short1 short
get nsize short
get null byte
getdstring name nsize
math tbl + short1
log name offset size
next i

Original script can handle only main game archive (game.arb) due to hardcoded offset. Here is fixed script which should work with all game archives properly.
