bz2unpak.exe

===============================================================

DISCLAIMER:

This program is not supported by anybody.
If you choose to run this program you do so AT YOUR OWN RISK!
===============================================================

WARNING:

You will need a *lot* of free disk space to run this.
I dont know what will happen if you try to run it without 
enough disk space.
Read the above disclaimer again, you have been warned.
===============================================================

USAGE:

put bz2upak.exe and the pak file you wish to unpack into the
same directory.
from a DOS prompt in that directory type -

bz2unpak <filename>

where <filename> is the name of your pak file

eg :

bz2unpak data.pak
bz2unpak bumps.pak
bz2unpak smtex.pak
===============================================================

WHAT IT DOES:

Used properly, the program will extract all the files from the
pak file into the same directory.
===============================================================

SOURCE CODE:

As I do not intend to use, support or continue development of
this unpacker, the source code is included here for you to refer
to in the event that you want to write a more friendly unpaker
or windows pak file explorer.

===============================================================
bz2unpak.c
---------------------------------------------------------------
#include <stdlib.h>

//unpacks the BZ2 data.pak
//does not use dircetory names
void main(int argc, char*argv[])
{
	int tot;//number of files
	int fhadr;//file header address
	int fadr;//file address
	int flen;//file length
	int i;
	char fname[255];
	char namlen;
	char *buf;
	FILE *pakfile;
	FILE *output;

	pakfile=fopen(argv[1],"rb");
	//get the number of files
	fseek(pakfile,16,SEEK_SET);
	fread(&tot,sizeof(int),1,pakfile);
	//get the address of the first file name
	fread(&fhadr,sizeof(int),1,pakfile);
	for (i=0;i<tot;i++)
	{
		fseek(pakfile,fhadr,SEEK_SET);
		//get the filename
		fseek(pakfile,4,SEEK_CUR);
		namlen=getc(pakfile);
		fread(&fname,sizeof(char),namlen,pakfile);
		fname[namlen]=0;
		//get the position
		fread(&fadr,sizeof(int),1,pakfile);
		//get size
		fread(&flen,sizeof(int),1,pakfile);
		// read it
		fseek(pakfile,fadr,SEEK_SET);
		
		buf=(char *)malloc(flen);
		fread(buf,sizeof(char),flen,pakfile);
		//write it
		output=fopen(fname,"wb");
		fwrite(buf,sizeof(char),flen,output);
		fclose(output);		
		printf ("%s: %d bytes\n",fname,flen);
		fhadr +=(namlen+17);
		free(buf);
	}
	printf ("%d files written OK!\n",tot,fhadr);
