Has anyone given "PC Building Simulator" a try? Tried compressing with msc + srep + lolz but unfortunately got a "-1" FreeArc archive corruption error at around 1.2% into attempted installation. Not sure if there's a trick to these Unity titles but it seems I'm yet to figure them out.

I'm not sure as to what is causing issues as I was able to get from 26gb to ~4gb so I'm certain the files can't already be compressed. Whats stranger is similar methods with the title "Outward" gave me similar final ratios, however "Outward" was able to decompress properly. My guess is that this might be an engine version issue, or with how Unity creates its packed files, but I'm honestly at a loss.

PC Building Simulator is just srep+lolz. Not sure why you're using msc.

L33THAK0R: This error message used Arc.exe from decompression?? Its probably used bad arc/cls.ini configuration or/and missing/wrong external exe/dll files these unpacking process.

Game Hierarchy Thanks to Fitgirl.

Textures that are TGA aka Targa files use lz4 compression that means that we need lz4 precompressor made to decompress TGA files
She has unpacked them all and made Xdelta patches

MSC+SREP+lolz

Models*.pak > srep+lolzi

Executables srep+lzma.

If Targa files can be precompressed it's possible to make this game as low as 11 GB

Can we know what methods are used just from the .bin/.arc file?

Hi all, I hate to always ask the most silly questions but could anyone who's been able to successfully compress and decompress "PC Building Simulator" share the options/arguments/commands that they used for srep & lolz? My initial attempt with msc + srep + lolz (msc because of the .mp3 OST files incl.) failed to decompress with an UnArc.dll error of "-1". I re-attempted with just srep + lolz as per the advice of the forum user "Masquerade" and saw a significant (80mb) reduction in the final output, however decompression still failed, with the same error code (-1) as the first attempt given.

Yo, i ain't that good but that happened to me recently, and the reason behind these were:

The .dll used for compression and decompression must be same.
The external compressor in arc.ini must be configured correctly.
Try setting the same arguments used in packcmd for unpackcmd.
Try some other scripts just for experimental purpose.

In my case, it was FIFA 20 and the issue for the error was the oo2core_6_win64.dll.

The one used for compression was around 1,061 KB
And the one used for decompression was something 1,041 KB
So i just replaced the .dll and boom it worked.

As for your case, it must be something like CLS-MSC.dll and so on.

Also, if you compressed it using DiskSpan then make sure the .dll matches since there are different versions of DiskSpan.

Please let me know if it helped .

What srep are you using for decompression?

cls-srep, srepinside or srep.exe? Use cls-srep.

For the mp3 soundtrack, use a mask (arc.groups)

arc.groups file (next to arc.exe

$mp3
*.mp3

-msrep+lolz/$mp3=mpz

mpz is mpeg audio compressor.
