ZLIB Compression file tutorial, no need to update arcs!!

[Miztah Raza]

Here's a ZLIB compression tutorial. The point of compressing files to ZLIB is so that you don't have to update the arcs. X-PacKer does not support updating the entries for most files other than the wrestler pacs, but, it can open/inject files into 'em. So basically, if we take out the part X-PacKer can't do(which is update the arcs for most non-wrestler pacs), then we basically blow open most of the game :)2

Before starting the tutorial I'd like to give thanks to the following people:

Tekken57 for suggesting to me to use ZLIB and explaining header info.

BrienJ for actually using ZLIB which is what led Tekken57 to telling ME to use it.

THQ for adding ZLIB support in SvR 2010, lol.

Okay, let's begin.

First off, we all know how to uncompress BPE files using X-PacKer, so, just as an example, I'll uncompress 000C.bpe from a wrestler PACH file, this will leave me with 000C.bpe and 000C.pac, X-PacKer can open/edit 000C.pac, so, I inject an edited texture, X-PacKer automatically saves, nothing new here.

Now, download ZDrop application, here:

http://www.mediafire.com/download/1jkog4jan7nimbs/zdrop.exe

(Not my program, I honestly do not remember who made this, but this is NOT my work)

Simply drag and drop the edited 000C.pac into the ZDrop application, a new file will be created in the same directory as the 000C.pac, with a .ZLIB extentsion.

Open the 000C.BPE in a hex editor. Also open the 000C.pac.ZLIB in the hex editor. Copy all the contents from 000C.pac.ZLIB, skip the first line in the 00C.bpe and paste the copied info from the second line onwards(hope that made sense, lol). Be sure to overwrite, not insert. You will notice that there will 'random' bytes from the old BPE that are still there, ZLIB files are almost always smaller than BPEs, that's why. So just fill the remaining bytes with 00s, this is called 'padding' the file, there's a command that automatically does this for you in HxD, it's called 'fill selection'. You simply select the 'left over' bytes from the BPE and use the fill selection command and fill it with zeroes.

Now, we go back to the header. The header still says BPE, well, that's wrong since it's no longer a BPE, so, we simply overwrite BPE with ZLIB0.

Hope you're still with me here, now, highlight ZLIB0 and look at the byte afer the 0x30(which stands for zero in the 'text' part, lol) it probably says 0x01, change that 0x12.

Done :)2

It may seem a little tough at first, but once you get the hang of it, you can compress files like this in no time ;)2

I'm also sorry for not knowing the 'technical' names for some things, so if you have a problem with that, go fk yourself, I tried my best :P2

I'm also sorry for not posting pics, I'm lazy, deal with it.

This also works for WWE '13 :)2

Cheers!

Good tutorial. Thanks for writing this up.

 

If I actually had time to finish coding x-packer 9, I may have implmented support for this

Hmmmm.... if your boss was to get kidnapped and locked away in an asylum for a week in Kazakhstan, would that be enough time for you to finish coding it? Because I think I can make that happen

[tekken57]

If you could make that happen, why only take my boss away for a week? Take her away permanently :D2

[Miztah Raza]

It's a her?

God dammit, my 'guys' are absolute pussies when they're around women.

Sorry dude.

[tekken57]

Yup, but she's like 100 years old

[Miztah Raza]

Yeah, but she's rich. Those assholes would sell me out in a heart-beat if she pays 'em enough.

[UndertakerWLF]

Thanks for posting this Miztah, very interesting stuff you do know your going to attract the 'I want pic crowds' and the 'I want a video crowd' lol

[Miztah Raza]

Yeah, but so far the only crowd I've attracted here is you and tekken :P2

[UndertakerWLF]

Give it time lol.

[bravebird31]

Well it got my attention. 

[nikethebike]

Give me a pic. I want it to be a screen shot of this tutorial nicely resized in MS paint.

[UndertakerWLF]

I would like a step by step video please

[bravebird31]

@UndertakerWLF ...in 3d bluray 1080p  

[tekken57]

Yeah, but she's rich. Those assholes would sell me out in a heart-beat if she pays 'em enough.

 

Excuses, excuses

[tekken57]

Now if only that darn x-packer v9 supported ZLIB files

 

[Miztah Raza]

I need to go change my pants....

[nikethebike]

Aww-wwe-some!

[UndertakerWLF]

Very nice Tekken, thanks for taking the time to work some more on Xpacker

[JBP]

BTW!  This works on WWE 2K14.  I have an xk3y and it doesn't play well with arc mods or file size changes.  I was able to add logos among other things with this and xpacker.

[Miztah Raza]

Great to know, JBP! I actually made a tool that ZLIB compresses the files. I'll release it tomorrow since this works on 2K14! Thanks!

[JBP]

GREAT!! That would be a ton of help!

[Lazarous]

you should make a video tutorial for dumb people like me lol

[IamCrazyPT]

you should make a video tutorial for dumb people like me lol

Why don't you buy X-packer? It's only 10$.
