Chaos Wars .UN2 (Seems very easy)

[Dazz]

I'm looking for a means to ripping the sprites from this game, but so far I've only found a japanese application that will extract the CG artwork, and is hard coded just to do that.

The format seems pretty standard, but I'm a moron when it comes to this stuff.

I'd love something that could just output the sprites in a .png format, with the correct palettes and offsets.

There's a couple files that use this format, they seem pretty much the same in structure - i've uploaded the smallest one here:

From what I gather, it contains the character's attack sprites, and their "basic" weapon above them.

Graphics:
4 bits/pixel
Big Endian
linear

Palettes:
4 bytes/colour
BGR
Big Endian
Tiled 8x2


Any and all help would be greatly appreciated.

I hate to bump, but I've not yet had any assistance on this yet... Any help?

Oh mang, I'm really sorry, I wish I had viewed this thread sooner.

I have no idea about how to convert the sprites to PNG, but luckily the data isn't compressed or encrypted, so I suggest you using TiledGGD.

Here's the script to unpack the UN2 files. Have fun! :

Code: Select all

# Chaos Wars UN2 format unpacker script for Quickbms
# Made by XeroNazoBlaze

ImpType Standard ;
Idstring "UNI2"
Get NULL1 long ;
Get NOFFILES long ;
Get NULL2 long ;
Get FFOM long ;
Math FFOM *= 2048 ;
Set FFOFFSET FFOM ;
GoTo 0x800 ;
For I = 0 < NOFFILES ;
Get NULL3 long ;
Get FOFFSET long ;
Get FSIZE long ;
Get NULL4 long ;
Math FOFFSET *= 2048 ;
Math FOFFSET += FFOM ;
Math FSIZE *= 2048 ;
Log "" FOFFSET FSIZE ;
Next I

Let me know if there's something wrong.
