FileForums - Best Compression Methods for 'Specific' Games. Q&A

Download the decryption tool from the attachment below (credits to atom0s & Gabriel Dehan). This EXE is specific to game version v1.1.5.5.
Drop the EXE into the game's root folder.
Open CMD prompt here.
Run the following command:

Code:

for /r %f in (*.pak) do Pak_Decrypt "%f" "%~df%~pf%~nf.zip"
Once the above command completes, run the next command:

Code:

for /r %f in (*.zip) do del "%~df%~pf%~nf.pak"
Once the above command completes, run the next command:

Code:

for /r %f in (*.zip) do ren "%f" "%~nf.pak"

Now you have a fully decrypted game.

Step 2: Compression

Make 2 archives.
Archive 2 will contain "Sounds_MISC.pak" and "Sounds_WEM.pak".
Archive 1 will contain everything else.

Start Size: 33.6GB

Method for archive 1:

Code:

xzlib+srep+lolz

Method for archive 2:

Code:

srep+lz4:l12

Final Compressed Size: 13.6GB

Couldn't find the answer through search. What compression method do I use for pdf files?
I think if we have a sticky thread about a general compression method for specific types of files, it would greatly help newbies like us.

This BMF compressor not repleceable using the BIM compressor usage the MSC/FreeArc? Newest or patched/fixed versions, from fix freezing DDS compression its available? (Win7 x64) Found BMP only fixed v2.01 copy from FreeArc usages. (v1.1 its very old.) This v2.0 its totally lost from net?

This BIM v0.03 version, support only 24bit BMP, TGA and PNM/PPM images. (No available more info this compression rate difference than BMF.)

MotoGP 22

Code:

xzlib+srep+lolz/$mp4=srep+lz4:l12

29.2GB ---> 16.6GB

I have stopped using zstd for videos and prefer lz4 instead because it is faster.

CLS-LZ4 library used by Shegorat.

Masquerade: Some code's contains ...lz4:l12 switches. This FreeArc 0.67 internal switches from lz4 algo?? Tested in Arc.exe with -mlz4:l12 don't work. Pure lz4 or lz4:h32m or lz4:h32m:b8m its ok.

I am using cls-lz4 plugin by Shegorat. I have amended my post to reflect this.

ZenStudios Pinball FX3 ".pxp" archives

1 Attachment(s)

Anyone given the ZenStudio's "Pinball FX" series a shot? Can't seem to find any information about the engine or the archives it uses. It (as well as all other ZenStudio titles) use a "*.pxp" archive format (File signature of 50 58 1A CD, decodes to "PX.Í"), and using the zlib codec under xtool picks up ~3 streams but crashes with a general decompression error after trying to parse them. Attached is a sample if anyone wants to have a look. Only mention I can find of this series/engine is this post, but cant find anything else online. There seems to be a QuickBMS script for decompressing these archives but unfortunately it doesn't seem to support the current iteration of ZenStudio's archive-type, introduced archives pertaining to more recent DLC.

There is a decompression tool by Ekey, but i think you need to be a member to download it.

I didn't include Ekey's unpacking tool as it serves the same purpose as the QuickBMS script, however its a tad more outdated and is less compatible with the more current iterations of the ".pxp" archive. For anyone interested I've attached the aforementioned tool, as well as the source code for Ekey's decompression library.
