Dance Mission 2 【勁舞團2】

[chrrox]

This game is using the nif file format so once this is extracted anyone can access the nif files.
full installer
ftp://ftp.games.seed.net.tw/pub/games/g ... 1.1.2).exe

Code: Select all

Start of archive 1st 4 bytes magic number 00 00 00 00
next 4 bytes files in archive ( after this file table begins)
begin and end with 00
1st 4 bytes are archive number / something to do with weather its a file or folder / unkown pattern?
2nd 4 bytes are location
Next 4 bytes are un compressed size
next 4 bytes are length of file
Next 4 bytes indicate compression seems to always be 01 00 00 00 ( I don't see any un compressed files :) )
next32 bytes are encrypted file name / file name hash?

here is a scan of the game.

I am guessing it is using md5 for the file names like spike girls did?
Then it uses the default zlib is my guess due to each file starting with 78 9C

Here are the main exe files and some sample pac files.

I have made a quick script here

Thanks so much I found where the file names are stored and I am going to tryy and use your great program to extract the files with their names. Ill post anything I find.
