Star Wars Bounty Hunter PC archive - BUNY extraction script

[enderdrag64]

Hi, I created this extraction script for the archives of the Aspyr PC port of Star Wars Bounty Hunter earlier today, hopefully it's useful to somebody.

 

endian little
idstring "BunyArchTheForge"
get UNKNOWN longlong
get UNKNOWNTWO longlong
get UNKNOWNTHREE longlong
get HEADERSIZE longlong
get FILENAMETABLEADDR longlong
get FILENAMETABLESIZE longlong
get UNKNOWNADDR longlong
get UNKNOWNSIZE longlong
for i = 0 < HEADERSIZE / 40
	get UNKNOWNFOUR longlong
	get UNKNOWNFIVE longlong
	get FILENAMEADDR long
	get FILENAMESIZE long
	get ADDRESS longlong
	get SIZE longlong
	savepos HEADERLOC
	xmath JUMPPTR "FILENAMETABLEADDR + FILENAMEADDR"
	goto JUMPPTR
	get FILENAME string
	goto HEADERLOC
	log FILENAME ADDRESS SIZE
next i

I would've attached it as a file but it seems .bms isn't an approved attachment format. This is my first post on this forum, please let me know if there's a better way to submit these, thanks!

Welcome. There is a download section specifically for BMS scripts and other applications. In here you should only put link to it.. https://reshax.com/forum/28-scripts-or-other-utilities/

Here is a full script to extract buny files.

Script for packing new/modified files to .buny archives (not reimport!). Requires -w option for quickbms.

[JohnLogostini]

So the script unpacks the files, and I can see all of the DDS files are valid. How do I go about getting the game to read the modified files? Do the files need to be packed back into data.buny?

as it appears the game is hard coded to look for data.buny
