Ah that'd definitely explain things, I didn't even think to see if I was using the wrong codec

First of all, bms2xtl exists so you half of the job is already done for you. The other half of the job is about 20 minutes and a bit of guessing work ;)

Yeah I was using bms2xtl, just thought rebuilding an archive would be the next step if I couldn't figure out how to pick up more streams.

Cheers for the help and testing mate :cool:

Update on Zen Studios ".pxp" archives

Over the last couple days I've been testing "BMS2XTOOL" on ".pxp" archives to try and see if through this method it's possible to both decrypt + expand the compressed streams present within a given ".pxp" archive, to make re-compressing said archives a viable prospect. However I've hit a roadblock unfortunately, as I can get xTool (v0.5.0) to detect some streams, but can't seem to figure out what codec to use, to actually process the majority of said streams.

Currently I'm associating the compressor type, "ZENPXP" with the "zlib" codec for use with "BMS2XTOOL", and combining this with the "reflate" codec in my arc.ini.

For anyone interested, attached below is a sample testing suite, as well as just a copy of BMS2XTOOL, with the appropriate resources to generate your own database for said sample, should anyone be interested in looking at this. I've also tried to see if it's been documented anywhere within QuickBMS the compression algorithm used for a given "comtype" in a QuickBMS script but alas this doesn't seem to be the case

VALORANT: Episode 4 Act 3

srep+lolz

23.5 GB> 7.2GB

okay I am having problems getting this to work what am I doing wrong
I place the wd1.xtl and xcompress in my xtool folder and use

xtool precomp -mwd1 common.dat common.tmp

it runs for a a few seconds and nothing happens it doesn't even make a common.tmp file

sorry I forgot to say this is for Watch dogs 1 using the database method posted here

Hey guys, what's the best method for The Walking Dead Definitive Series? I'm using DiskSpan GUI btw. Thank you.

Telltale game, so all of the ttarch2 files that have headers beginning with ECTT are encrypted using Blowfish encryption.

In this case, DiskspanGUI has nothing to handle those files. I would use cls-ttgd by Shegorat, but that isn't a public tool.

Use this to decrypt the files: https://www.fileforums.com/showthread.php?p=483980

Then, compress with xtool(zlib+reflate)+srep+lolz. You can re-encrypt your decrypted files from earlier using the same tool to get MD5 perfectiom upon installation.

hi guys, i want try to repack Harvest Moon: One World

Seems to use Unity, try XTool or UBT?

precomp xtool doesn't work

Hello everybody! A simple question: does a more powerful PC give better compression results rather then a less powerful one?

No, only the speed is different.

Did I do something wrong? I used the tool you told me and I checked MD5s before and after decryption to make sure the files are decrypted, and they were different so I assumed the decryption was successful.

To assume makes an ass out of u and me :p

Anyways...

Make sure you used the correct key for decrypting the data. Check in hex editor that the decrypted file starts with ZCTT. ECTT will be an encrypted archive, ZCTT means you did it correctly.

Test on a single TTARCH2, decrypt and see if you can inflate it with XTool. If you decrypted it right, you will get correct ZCTT header and XTool will be able to precompress the data.

Harvest Moon: Its probably use SREP and RZ (v1.00) and two LOLZ version (last and older v20d3) compressors used from final packing. And ISDone x64 v0.6.0.2!

This piggy and fbz compressor tell someone something?
